Hey after updating Android Studio to 3.1 Stable version i am getting following error to all my projects. Any help will be appreciated.
Could not download kotlin-reflect.jar (org.jetbrains.kotlin:kotlin-reflect:1.1.3-2): No cached version available for offline mode
I guess its Kotlin version related issue.
First try to update your kotling version. I guess latest version is 1.2.31
The version of Kotlin to use is usually defined as the kotlin_version property:
buildscript {
ext.kotlin_version = '1.2.31'
repositories {
mavenCentral()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
For details: https://kotlinlang.org/docs/reference/using-gradle.html
I have answered a similar question here . One of the key is to update the kotlin plugin from settings in android studio.
try this
Android studio -> File -> Invalidate Caches
Sorry, Silly Mistake figure out just Uncheck Offline checkbox from Gradle settings. :) Download all dependencies by build gradle online.

I'm having the following error message when trying to do refactor -> migrate to AndroidX
The gradle plugin version in your project build.gradle file needs to
be set to at least com.android.tools.build:gradle:3.2.0 in order to
migrate to AndroidX
Although I have version higher specified in build.gradle...
app/android/build.gradle
buildscript {
dependencies {
classpath 'com.android.tools.build:gradle:3.4.2'
I have another app/android/app/build.gradle.
I solved it by changing version to 3.4.1 and back to 3.4.2.
now error is gone..
in my case,
apply
classpath("com.android.tools.build:gradle:4.0.1")
instead of
classpath("com.android.tools.build:gradle:${version.gralde}") -> even version.gralde is 4.0.1
:thinking :) maybe android studio can't identity the plugin version if it references to an external value
Only change gradle version of a project may be not enough. Please also check gadle versions of the dependies. Make sure every gradle version of a depency is beyond 3.2.0. Have a try, please.
I just updated to Android Studio 3.0 and I'm getting this error with an existing project:
Kotlin not configured
When I go to Tools>Kotlin>Configure Kotlin in Project, I get an error saying "no configurators available". Also get the error below with the red java:
I've also tried:
Restarting
Clean and Rebuild
Invalidate caches/restart.
I first tried with invalidate cache/ restart option but it doesn't help me.
When I updated Kotlin to 1.1.60 in project's gradle file, problem is solved.
Also, use this in app's gradle for stdlib
implementation "org.jetbrains.kotlin:kotlin-stdlib:1.1.60"
instead of
implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:1.1.60"
In Android Studio, click on File -> Invalidate Caches / Restart... , then select "Invalidated and Restart". This solved my problem.
This error also occurs if you have the mavenCentral() repository missing in allprojects.
Your build.gradle (:app) should contain at least this:
allprojects {
repositories {
google()
mavenCentral()
}
}
jcenter() would work as well (for now), but that repository reached end-of-life and shouldn't be used any more.
Closing and restarting Android Studio works for me in that case. Important is that there are no other projects opened in Android Studio before you close it. I suspect that closing Android Studio with multiple opened project windows sometimes messes up the configuration especially after plugin upgrades etc.
Important Update
You should check JDK version before setting config
Kotlin gradle config page has detailed information about this.
Step 1
Check kotlin version in project level gradle file.
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
For kotlin_version '1.2.x' Use jdk NOT jre
Step 2
Check JDK version in File > Project Structure
Or check in build.gradle
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
If no JDK version is set in Project Structure, then choose by Android Studio version
JDK version is 1.7 for Android Studio Version < 2.2.1
JDK version is 1.8 for Android Studio Version < 2.2.1
Because Android Studio is bundled with jdk 1.8 since 2.2.1 version.
You have 3 options of kotlin stdlib, choose according JDK version
implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version" //jdk_version == 1.8
implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version" //jdk_version == 1.7
implementation"org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" // jdk_version is < 1.7
if kotlin version is'1.1.x' Use jre NOT jdk
implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" // or jre8
Update Kotlin Version?
You can update Kotlin version from Tools > Kotlin > Configure Kotlin Updates
Kotlin-stdlib-jre7 is deprecated since 1.2.0 and should be replaced with kotlin-stdlib-jdk7
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
I have faced this issue recently... when I updated to Android Studio 3.1 .
I did a few things to fix this.
First I updated the Kotlin version in my app gradle file and added
implementation "org.jetbrains.kotlin:kotlin-stdlib:1.2.31"
in my app gradle file. But this alone didn't fix it.
Then uninstalled the kotlin plugin from settings, restarted Android Studio and installed it again.
EDIT :
This is my project gradle file
buildscript {
ext.kotlin_version = '1.2.31'
repositories {
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.1'
classpath 'com.google.gms:google-services:3.1.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.31"
}
}
allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" }
google()
}
}
And this is my app gradle file
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
android {
compileSdkVersion 27
buildToolsVersion '27.0.3'
defaultConfig {
...
}
buildTypes {
...
}
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
kapt { generateStubs = true }
}
repositories {
...
}
dependencies {
...
...
implementation "org.jetbrains.kotlin:kotlin-stdlib:1.2.31"
...
...
}
apply plugin: 'com.google.gms.google-services'
just delete .idea folder from project,and run android studio again, it will resolve KOTLIN NOT CONFIGURED issue.
A common reason of the "Kotlin Not Configured" message is an internal Android Studio exception due to a bad plugin.
In order to fix that you should disable the bad plugin.
When such plugin crash occurs, on the "Wellcome screen" you'll see a small notification (see illustration image) where you can click it and disable the bad plugin:
None of the other solutions solved my problem. I ended up figuring out that the problem lied in the google services version. Just update it to the latest.
Top level gradle at dependencies:
classpath 'com.google.gms:google-services:4.1.0'
In my case, after the update of Android Studio and plugins, I could create new projects, but my old projects were having "Gradle Sync Issues".
The solution was in File/Project Structure.../App/Dependencies:
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
And then I just updated the Kotlin version in my project build.gradle:
From:
ext.kotlin_version = '1.2.30'
To:
ext.kotlin_version = '1.3.21'
Then I tried Sync again.
Obs: You can check your Kotlin version in Tools/Kotlin/Configure Kotlin Plugin Updates
I have tried all above solutions but non of them works for me.
Then finally I got success with below solution, so it may helpful for some one like me.
Delele all .iml files (in root project, libraries and modules)
Rebuild project
In my case I had to update Android studio from version 3.4.1. to 3.5 and it resolved the kotlin not configured error.
Delete .AndroidStudio3.6 folder in C:\Users\Username and re-open Android studio works for me
The only fix for me was adding
apply plugin: 'kotlin-android-extensions'
in build.gradle (:app)
One other point to check is version of your Gradle in gradle-wrapper.properties, if you use one.
Make sure that
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip
Has version 4.1 or higher.
You may also have the following in your build.gradle:
task wrapper(type: Wrapper) {
gradleVersion = '4.1'
distributionUrl = "https://services.gradle.org/distributions/gradle-$gradleVersion-all.zip"
}
Where Gradle version is lower that 4.1
Though I see that the question already has answers that work, one might also try the following solution.
Right click on the file name (Main.kt) -> Run 'Main.kt'.
This will download a gradle file from the gradle.org website.
Wait for it to unzip. The errors were cleared.
In my case, it was a broken update of one of the plugins I've used. Check your error logs from Android Studio this will lead you to what is the problem.
Simply Create a new Activity and select its language to kotlin Android studio Automatically configured kotlin for you.
I have the Android studio 3.0 Canary preview and am able to build fine there. When I try to build on jenkins with gradlew I receive
Could not find com.android.databinding:baseLibrary:3.0.0-alpha8.
I thought maybe the google() repo wasn't working but you'd think that would error out itself so I replaced
google()
with
maven { url 'https://maven.google.com' }
and I still get the same error. The only reference that I have in my build.gradle for databinding is
android {
dataBinding.enabled = true
}
my gradle wrapper has a distribution url of
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-milestone-1-all.zip
does anyone have an Idea of what I'm doing wrong or let me know if you need more information.
Same error here.
It's because you use Android Studio Canary Version.
Build Tools are include in package directly:
android-studio\gradle\m2repository\com\android\tools\build\gradle\3.0.0-alpha9
Are you sure that version exists? Looking here it seems like it doesn't.
Keep in mind that 3.0.0-alpha8 (alpha9 as of now) is for classpath 'com.android.tools.build:gradle', and not necessarily other dependencies
You can use the local gradle like this:
I was syncing fine and then suddenly when I tried to run a test on a device from Android Studio I started getting the error:
Error:(1, 0) Plugin is too old, please update to a more recent version, or set ANDROID_DAILY_OVERRIDE environment variable ...
I've looked around and I found from the gradle website that the latest version is 2.10, I tried adding that to my dependencies with no luck. I've tried various version numbers with various errors like the following:
Could not find com.android.tools.build:gradle:2.1
Searched in the following locations ...
I understand from all the searching I've done that its clearly a wrong version of gradle - but what IS the current version label I should be using, and how do I know it is installed on my machine ? I've always kept Android Studio updated.
So I currently have in the build.gradle:
dependencies {
classpath 'com.android.tools.build:gradle:2.0.0-alpha1'
}
UPDATED (28/03/2017):
2.4.0-alpha3 is the latest release
classpath 'com.android.tools.build:gradle:2.4.0-alpha3'
Check https://bintray.com/android/android-tools/com.android.tools.build.gradle/view for the latest gradle versions.
2.0.0-alpha1 is on the Canary channel and apparently these releases come with an expiry date. 2.0.0-alpha3 is the latest release. Switch to
classpath 'com.android.tools.build:gradle:2.0.0-alpha3'
and you should be fine. Keep checking http://tools.android.com/tech-docs/new-build-system to know the latest releases.
You might run into some Dex error. I had to do Build > Clean Project once to get it to work.
Change your existing configuration with this
In your project view, select Gradle Scripts
Open gradle-wrapper.properties
Change this line:
distributionUrl=https\://services.gradle.org/distributions/gradle-2.4-all.zip
with
distributionUrl=https\://services.gradle.org/distributions/gradle-2.8-all.zip
Go to build.gradle (Project: your_app_name)
Change this line
classpath 'com.android.tools.build:gradle:2.0.0-alpha1'
to this
classpath 'com.android.tools.build:gradle:1.5.0'
Don't click Sync Now
From menu choose File -> Invalidate Caches/Restart...
Choose first option: Invalidate and Restart
Android Studio would restart. After this, it should work normally
Hope it help
Now com.android.tools.build:gradle:2.0.0-alpha3 is old
use this
com.android.tools.build:gradle:2.0.0-beta2
If your having trouble getting the plugin to resolve. Check that your including jcenter() (Jcenter) in your repositories for the buildscript. Google does not publish the plugin to mavenCentral() (Maven Central).
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.0.0-alpha3'
}
}
As others have mentioned the latest ATM is 2.0.0-alpha3 but that could change at any time. Here is the source of truth on the latest available version:
https://jcenter.bintray.com/com/android/tools/build/gradle
As for the actual error here is the best answer is in is link. TLDR, undocumented feature of the non release plugins is they expire and you have to update.

Just solved by doing the following steps:
1 - Open gradle-wrapper.properties
Replace
distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip
with
distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip
2 - Open build.gradle (Project: app_name)
Replace
classpath 'com.android.tools.build:gradle:2.2.0-alpha3'
with
classpath 'com.android.tools.build:gradle:2.2.1'
I updated the Android Studio version 2.0 and was using normally. When I created a new project today, it is displaying the error Plugin is too old, please update to a more recent version, or set ANDROID_DAILY_OVERRIDE environment variable to
I realized that this problem occurs only when I create a new project. In previous projects developed, the problem does not occur and I realized that gradle is different
classpath 'com.android.tools.build:gradle:1.3.0'.
I have to update with the same set of old projects?

UH OH, Google Notice: "This website no longer provides downloads for Android Studio."
(Old 'channel' links no longer work. Links in this answer have been updated to the new formats, make sure to change your bookmarks if you were using them)
You need to update the version of the gradle tools you are building with. This can be found inside the dependencies section of your build.gradle. You have 3 options you can update to:
The latest stable version referenced in the release channel as of 2nd March, 2017 is
classpath 'com.android.tools.build:gradle:2.3.0'
Or the latest beta version via preview channel as of 15th February, 2017 is
classpath 'com.android.tools.build:gradle:2.3.0-beta4'
And the latest alpha version also from the preview channel as of 21st March, 2017 gives you the option to use
classpath 'com.android.tools.build:gradle:2.4.0-alpha3'
Updating requires you to also upgrade the gradle wrapper. As of 20th February '17, the newest is:
distributionUrl=https\://services.gradle.org/distributions/gradle-3.4-all.zip
On android studio you can find your wrapper by changing to the project view and looking in gradle/wrapper/gradle-wrapper.properties
Sometimes after changing wrapper the project will fail to compile with an error like “Minimum supported Gradle version is 2.14.1. Current version is 2.10. Try changing Gradle distribution version to...” despite already having the correct version in gradle-wrapper.properties. If that happens try the following:
Go to Settings > Build, Execution, Deployment > Gradle
Under Project-level settings ensure that Use default gradle wrapper (recommended) is the selected option, then re-build your project.
(Additional Note: With regards to the alpha and beta versions - there is not always a newer build than the stable version when I check, in those cases I've just given values for the previous version. This allows you to roll back to that version if you experience issues with the released version)
In new project change this part:
dependencies {
classpath 'com.android.tools.build:gradle:2.0.0-alpha1'
with
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'.
If you're not experienced user, please stick with Android Studio's Updates Stable Channel. I suppose you got Android Studio from Canary Channel.
Note that:
The Canary Channel for Android Studio delivers the bleeding edge updates on a roughly weekly basis. While these builds do get tested,
they are still subject to bugs, as we want people to see what's new as
soon as possible.
From: http://tools.android.com/download/studio/canary
You don't need to change dependencies of your older projects. They should run normally on the latest version.
Same problem on update.
this Fixed it for me:[build.gradle]
classpath 'com.android.tools.build:gradle:2.0.0-alpha3'
or
classpath 'com.android.tools.build:gradle:2.0.0-beta2'
Just in Advanced System Settings in Windows Properties, add a new environment variable with the name ANDROID_DAILY_OVERRIDE and the given value in error message. Restart android studio and you will be ready to go
As of April 5, 2016 this worked for me:
classpath 'com.android.tools.build:gradle:2.0.0-rc3'
gradle version you need became
classpath 'com.android.tools.build:gradle:2.0.0-beta7'
Which requires you to use the gradle wrapper for 2.10 if you were still using previous version
distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip
On android studio you can find your wrapper by changing to the project view and looking in gradle/wrapper/gradle-wrapper.properties
classpath: com.android.tools.build:gradle:+
This will solve the problem by updating gradle to latest one.
However it is dangerous(will code in alpha stage) & will also give warnings.
If you are using Android Studio 2.0 Preview I can suggest using 'beta' updates channel instead of 'stable'. It will allow you to receive latest gradle configuration changes. You can change updates channel in Settings - Appearance & Behavior - System Settings - Updates. Select Automatically check updates for [Beta Channel]
In order to know actual version of gradle classpath and distributionUrl (check Nick Caroso's answer) you can create new empty project and see these values there.
You need to change your gradle-wrapper.properties file in gradle/wrapper folder of your app, change your distributionUrl as this:
distributionUrl=http\://services.gradle.org/distributions/gradle-2.8-all.zip
Use http: or https:\ as per your requirement.
Then just clean your project and you are done!!!
Side Note :
classpath 'com.android.tools.build:gradle:2.0.0-alpha3'
is available now, if you want to use latest version.
Also you can take advantage of instant run feature of android studio using this, which is not available in gradle version below 2.0.0
Android Studio 2.0 has an update project to use instant-run. For those like me with little brains:
http://tools.android.com/tech-docs/instant-run
The current version of Android Studio 2.0 is Beta 6.
try update gradle to 2.10
for mac, tha path is Android Studio > Preferences > Builds,Execution,Deployment > Build Tools > Gradle
of course you must download gradle 2.10 before
I got the same error on 04/07/2016 with
'com.android.tools.build:gradle:2.2.0-alpha2' and gradle wrapper 2.10
then, I just changed to
'com.android.tools.build:gradle:2.2.0-alpha3'
now I have no problems.
Hope this help peple.
I have resolved this way.
Steps:
Open gradle-wrapper.properties file and change distributionUrl to https\://services.gradle.org/distributions/gradle-2.14.1-all.zip.
Open root level build.gradle and change classpath to com.android.tools.build:gradle:2.2.2.
Sync your Android studio project.
Reference screen shot:
Done.
just change
classpath 'com.android.tools.build:gradle:2.0.0-alpha '
or
classpath 'com.android.tools.build:gradle:2.1.0'
I change my classpath from 'com.android.tools.build:gradle:2.2.0-alpha4'
to classpath 'com.android.tools.build:gradle:2.2.0-alpha5'
and clicked "try_again" when the warning appears "unable to find cached classpath" you just click "sync", this worked like a breeze.
This problem occures generally when the IDE(android studio) in which project is build and the project are not in compatible gradle plug in. Please check the link below
http://tools.android.com/tech-docs/new-build-system/version-compatibility
In my case i had created a project using AS 1.0/2.0 version, and later imported in studio version new it gave me error then I opened project in older version of AS it worked.
you can also check http://tools.android.com/tech-docs/new-build-system
File -> Project Structure -> Project -> Android Plugin version = 2.2.3
Working fine of Android Studio 2.2.3
