Failed to resolve: com.android.databinding:library:3.1.2

After updating android studio 3.1.2 my existing project gives error at
dataBinding.enabled = true
error is as follows-
Failed to resolve: com.android.databinding:library:3.1.2
Failed to resolve: com.android.databinding:adapters:3.1.2
my gradle dependency are as follows-
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:25.1.0'
implementation 'com.android.support:recyclerview-v7:25.1.0'
implementation 'com.android.support:preference-v7:25.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.0-beta3'
implementation 'com.firebase:firebase-jobdispatcher:0.5.0'
// Instrumentation dependencies use androidTestCompile
// (as opposed to testCompile for local unit tests run in the JVM)
androidTestImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support:support-annotations:25.1.0'
androidTestImplementation 'com.android.support.test:runner:0.5'
androidTestImplementation 'com.android.support.test:rules:0.5'
}
I also tried
android.databinding.enableV2=true
but its also not working
When I tried to update build tool version to 4.4 then I found this error. I f I do not update the build tool version then its working fine.

check it this below code in your project level gradle file ..
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

According to the Android Team answer you had to add
google()
too all repositories
and priority is important. so other repositories must be added after google()

Downgrade to 3.1.0 in project level build.gradle file, then rebuild the project.
dependencies {
classpath 'com.android.tools.build:gradle:3.1.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
I hope this helps

I also has the same issue I ensured that I added google() to all repositories and also I downgraded gradle to 3.1.0 from 3.1.4 and my project was successfully build.
Another TIP: We can also add the below code to our build.gradle(project) which takes cares of libraries conflicts with new dependencies
configurations.all {
resolutionStrategy {
force"com.android.support:supportannotations:$androidSupportVersion"
force "com.android.support:support-v4:$androidSupportVersion"
force "com.android.support:appcompat-v7:$androidSupportVersion"
force "com.android.support:design:$androidSupportVersion"
force "com.android.support:recyclerview-v7:$androidSupportVersion"
}
}
And you can keep your libraries in a separate file such as libraries.gradle and include them in build.gradle(project)
buildscript
{
apply from: "./libraries.gradle"
}

I added Data-Binding to my project and the next time I build project, I faced the same issue, more specifically logcat displayed this message:
Failed to resolve: com.android.databinding:library:3.1.2
Failed to resolve: com.android.databinding:adapters:3.1.2
As per accepted answer, I checked my Project Level Gradle File to see whether it was missing google() in its repositories, but it was already there.
Build multiple times, but all in vain.
Then I did what my Android Master once told me to do, just in case when everything fails.
File -> Invalidate Caches/Restart.
Next time the project opened it build successfully.

gradle dsl method not found 'compile()' Error:(10,0)

I want to use Gson and Retrofit to interact with an API. According to the documentations, I add theses lines into the build.gradle of my project:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
mavenCentral() //this line
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
compile 'com.google.code.gson:gson:2.7' //this line
compile 'com.squareup.retrofit:retrofit:1.9.0' //this line
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
mavenCentral() //and this line
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
but I have these errors :
Error:(10, 0) Gradle DSL method not found: 'compile()' Possible
causes:The project 'TempoEDF' may be using a version of the
Android Gradle plug-in that does not contain the method (e.g.
'testCompile' was added in 1.1.0). Upgrade
plugin to version 2.3.3 and sync projectThe project
'TempoEDF' may be using a version of Gradle that does not contain the
method. Open Gradle wrapper
fileThe build file may be missing a Gradle plugin. Apply Gradle plugin
So I used the Gradle plugin like my IDE wants to:
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
apply plugin: 'gradle'
compile 'com.google.code.gson:gson:2.7'
compile 'com.squareup.retrofit:retrofit:1.9.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
but I have this error :
Error:(10, 0) Plugin with id 'gradle' not found. Open
File
What did I do wrong?

so according to the documentations i add theses lines into the build.gradle of my project
Please note the comments in that file:
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
I do not know what "documentations" that you read that told you to put these things in the project-level build.gradle file. Please consider providing links, so that we can get that material fixed.
To get past this problem, remove the changes that you made to this file. Then, add those dependencies to the module's build.gradle file (e.g., app/build.gradle in a typical Android Studio project).

how to add a project level dependency in gradle

I have an app and an android library in my application, in development env i would like to provide a project level dependency i.e. dependency in the
(Project:XXX) build.gradle file.
This is how my project level build.gradle looks (partial view)
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'
compile 'io.reactivex:rxandroid:1.1.0'
// Because RxAndroid releases are few and far between, it is recommended you also
// explicitly depend on RxJava's latest version for bug fixes and new features.
compile 'io.reactivex:rxjava:1.1.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
I get an error Gradle DSL method not found : compile().
Is there a way in android to provide common project level dependency.

You can't add dependencies to any other scope except of classpath in the buildscript block.
Here's how you declare a project dependency (in another project, not in buildscript):
dependencies {
compile project(':shared')
}

You are using the dependencies block inside the buildscript. It is wrong.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'
}
}
dependencies {
compile 'io.reactivex:rxandroid:1.1.0'
compile 'io.reactivex:rxjava:1.1.0'
}

gradle DSL method not found: 'compile()' persisting error

This is what my gradle file looks like http://codeshare.io/RWMpl , its throwing a small error saying:
gradle DSL method not found: 'compile()' .
My gradle file :
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.2.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
compile 'org.ektorp:org.ektorp:1.4.2'
}
allprojects {
repositories {
jcenter()
}
}
I followed the advice on THIS thread(see the accepted answer) , but i still get the following error:
gradle DSL method not found: 'compile()'.
Why ?

Usually, there is a Project build.gradle and a Module build.gradle.
The screenshot that you shared was of your Module build.gradle.
This error seems to me as, you have an android block in your Project build.gradle file.
Remove android block from Project build.gradle and the app will compile fine..

You using a wrong gradle file. Check for build.gradle(Module:yourmodulename), this is where you have to update.

Gradle errors while adding dependencies in build.gradle

I've tried to included cards library in my project using the below code in my build.gradle file.
buildscript {
repositories {
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.1.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
dependencies {
//Core card library
compile 'com.github.gabrielemariotti.cards:cardslib-core:2.0.1'
//Optional for built-in cards
compile 'com.github.gabrielemariotti.cards:cardslib-cards:2.0.1'
//Optional for RecyclerView
compile 'com.github.gabrielemariotti.cards:cardslib-recyclerview:2.0.1'
//Optional for staggered grid view support
compile 'com.github.gabrielemariotti.cards:cardslib-extra-staggeredgrid:2.0.1'
//Optional for drag and drop support
compile 'com.github.gabrielemariotti.cards:cardslib-extra-dragdrop:2.0.1'
//Optional for twowayview support (coming soon)
//compile 'com.github.gabrielemariotti.cards:cardslib-extra-twoway:2.0.1'
}
}
allprojects {
repositories {
jcenter()
mavenCentral()
}
}
But when compiling, android studio is throwing up errors as below.
Error:(23, 0) Gradle DSL method not found: 'compile()'
Possible causes:The project 'cardslib_1' may be using a version of Gradle that does not contain the method.
Open Gradle wrapper fileThe build file may be missing a Gradle plugin.
Apply Gradle plugin
I'm guessing the reason to be gradle version, which is lower in libraries I'm including.
How to know the gradle version my dependencies are using and how to adjust them to my project.
When I thought to add the libraries, maven has repositories in aar file which I don't think will let you know the gradle version.
Thanks for any help in this regards.

You're adding the dependencies in the wrong place. They should be outside of the buildscript section and in the modules/applications build.gradle.
Parent build.gradle. This should be in the root directory of your project
buildscript {
repositories {
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.1.0'
}
}
allprojects {
repositories {
jcenter()
mavenCentral()
}
}
Module build.gradle. This should be in the folder of the module you're trying to add the dependencies to.
apply plugin: 'com.android.application'
android {
// Android related settings go here
}
dependencies {
compile 'com.github.gabrielemariotti.cards:cardslib-core:2.0.1'
compile 'com.github.gabrielemariotti.cards:cardslib-cards:2.0.1'
compile 'com.github.gabrielemariotti.cards:cardslib-recyclerview:2.0.1'
compile 'com.github.gabrielemariotti.cards:cardslib-extra-staggeredgrid:2.0.1'
compile 'com.github.gabrielemariotti.cards:cardslib-extra-dragdrop:2.0.1'
}
This assumes that the structure of your project is something like
Project
|___build.gradle
|___Module
|____build.gradle
