re-sync Gradle using Command line

Im building script that will change some info in gradle flavors dynamic and then build apk Using gradlew assemble' + $UsableProjectName + 'Release
Now my problem is the new flavor i have added is not seen by gradle yet or in the project index files, so i need to click on gradle sync to be able to recognise it and run successful build.
I have tried :
gradlew --recompile-scripts
and
gradlew assemble
But after running both of them i still cant see the new flavor until i do manual sync from the android studio.
Is there away to sync the gradle using command line ?

It shall work without doing gradle sync.
do run command 'gradlew tasks' to see list of 'Build Tasks'; new flavor shall be listed as 'assembleflavor1' or 'assembleflavor2'.

Configure Bamboo for Android Gradle based Project

I am trying to setup Bamboo for my Gradle build system based Android Project.
I have done the following setup on Bamboo.I'm done with rest of all setup upto project repository path.
I want to run the following tasks using gradlew for android
clean assembleDebug LintDebug
For that I have created new task called Gradle Wrapper.
Below is the Gradle Wrapper Configuration
When I am executing gradle wrapper task, I am getting the following error.
Caused by: java.lang.IllegalStateException: Cannot find executable 'D:\AndroidDemo\gradle-2.10\bin\gradlew.bat'
Note :- Standalone Gradle is working fine on local machine with all the tasks(clean assembleDebug LintDebug)
Gradle_Home = D:\AndroidDemo\gradle-2.10\bin(Local machine)
Can anyone suggest a solution for the same?

I also had some initial difficulties to set up Bamboo to build an Android project using Gradle.
First of all, make sure that you have the Gradle wrapper (gradlew) in your repo. (Seemingly that's the situation in your case). It seems to me, however the Gradle wrapper ignores the system default Gradle distribution (set by the GRADLE_HOME env var), and always downloads a Gradle version mandated by the Android Build tools.
Also make sure, that the Android SDK root environment variable (ANDROID_HOME or ANDROID_SDK_ROOT) is pointing to the SDK's root directory (e.g. $ export ANDROID_HOME="/opt/android-sdk/")[1].
Restart Bamboo after applying the environment variable changes.
In Bamboo, in the build tasks lists, add a new Script task. The interpreter should be '/bin/sh or cmd.exe', the script location should be 'inline', and the script body should contain the call for the parametrized Gradle wrapper, e.g.
gradlew clean build
Point the working subdirectory to the Gradle wrapper's relative location (to the repo root), if necessary.
[Sample Bamboo Android Gradle build script]
After these steps, Bamboo should execute the Gradle wrapper, which in fact should perform the actual build steps.

android studio use sync project with gradle files action

I want to use sync project with gradle file in command line but I dont know how to do
like this :
It besides do ./gradlew build also do other things
For example, in a file is written to a local library name android-test
than in settings.gradle read this file and call include ":${android-test}" .if I use AS sync project with gradle files button，AS can load
module to project , but when I run ./gradlew build, it doesn't work.
But I have developed a plugins, and I want to use this action, so how to call this function ?

Building and syncing from the command line is really simple. In the root of your project you can invoke the gradle wrapper's build command with
./gradlew build
To get a list of all available build tasks for your project:
./gradlew tasks

"./gradlew build" and "./gradlew tasks" in the path of your project.
more commands and steps here:https://developer.android.com/studio/build/building-cmdline.html

The action id is Android.SyncProject, so you can call it in your plugin:
ActionManager.getInstance().getAction("Android.SyncProject").actionPerformed(e);
You can find it in android-plugin.xml, maybe line 161.
Also in SyncProjectAction.java, line 36 you can find its text.

Building Android Studio project on Jenkins? android.compileSdkVersion is missing

I'm trying to set up my first Android project to build on Jenkins.
I'm running Jenkins 1.6.2 with version 1.24 of the Gradle plugin. Running on Windows 7 Professional SP1.
I've installed Android Studio and the Java7 JDK on my build machine, and a checked-out version of the software builds just fine, through Android Studio or when running gradlew.bat from the command line. But I can't get the Invoke Gradle script build task to work, within my Jenkins job.
There is a pair of radio buttons, on the configure project page:
Invoke Gradle
Use Gradle Wrapper
If I select "Invoke Gradle", I'm asked to select a "Gradle Version", which is something I setup in Configure System.
I created a gradle installation with GRADLE_HOME set to "D:\Program Files\Android Studio\gradle\gradle-2.2.1". That gives me a warning that "D:\Program Files\Android Studio\gradle\gradle-2.2.1 is not a directory on the Jenkins master...."
And when I run a build, I get an error "Can't retrieve the Gradle executable".
Which is probably related to the gradle plugin complaining about the directory. But the directory is correct. I've tried it with '/' instead of '\', and it made no difference.
Since that didn't work, I tried the alternative, "Use Gradle Wrapper". There's a checkbox: "From Root Build Script Dir". Whether I check it, or not, I get "java.lang.IllegalArgumentException: android.compileSdkVersion is missing!"
I've set both JAVA_HOME and ANDROID_HOME, so that's not the issue.
Any ideas?
As a followup, I delete the gradle task, and added an Execute Windows batch command task:
SET ANDROID_HOME=d:\Program Files\Android\sdk
SET JAVA_HOME=d:\Program Files\Java\jdk1.7.0_79
.\gradlew.bat clean
When I run that, I still get that error.
But when I run those commands from a command line on the build machine, they work just fine.
What could be different, when running gradlew.bat from Jenkins, than when running it from the command line? The Jenkins service is configured to use the same user as I'm logged in as, when I'm running from the command line. I've tried explicitly setting each and every environment variable I have set in the command line, in the Jenkins task, and I'm still seeing the error.
Any ideas?

Your local.properties file must contain:
sdk.dir="path to your android sdk"

I'm also using jenkins for building my apps and had a similar problem.
I fixed it by executing the gradle wrapper via jenkins without using the jenkins gradle plugin.
cd $WORKSPACE
./gradlew assembleRelease
And if you want lint add a second shell exec with
cd $WORKSPACE
./gradlew lint
Note that these commands are for a linux system but they will work just fine on windows (had a windows build server some time ago and did the same thing)

I met this problem too, but I don't know whether my solution suit for you.
My situation is below, in my project build.gradle file:
apply plugin: 'com.android.library'
apply from: 'maven_push.gradle'
dependencies {
......
}
android {
compileSdkVersion 19
buildToolsVersion "21.1.0"
......
}
When i run: gradle clean build, error message show:
* Where:
Script 'C:\xxxxxx\Project\maven_push.gradle' line: 32
* What went wrong:
A problem occurred evaluating script.
> android.compileSdkVersion is missing!
My solution is change the position of this script apply from: 'maven_push.gradle' to the bottom in build.gradle file, and BUILD SUCCESSFUL!:
apply plugin: 'com.android.library'
dependencies {
......
}
android {
compileSdkVersion 19
buildToolsVersion "21.1.0"
......
}
apply from: 'maven_push.gradle'
I think you should pay attention to the "Where" message in the error command line.

I can't be sure it's gonna solve your issue, but maybe you can consider using the sdk-manager-plugin which downloads and installs the android sdk directly from gradle.
If it works, it probably won't tell you why your current configuration is not working, but at least you won't be stuck anymore.

Android Studio how to run gradle sync manually?

I'm debugging Gradle issues in Android Studio and see references to "Run gradle sync", but I'm not sure how to run this command.
How do I run "Gradle sync" from Android studio or Mac terminal?

Android studio should have this button in the toolbar marked "Sync project with Gradle Files"
EDIT: I don't know when it was changed but it now looks like this:
EDIT: This is what it looks like on 3.3.1
OR by going to File -> Sync Project with Gradle Files from the menubar.

WARNING: --recompile-scripts command has been deprecated since gradle's version 5.0.
To check your gradle version, run gradle -v.
./gradlew --recompile-scripts
it will do a sync without building anything.
Alternatively, with command line in your root project
./gradlew build
It will sync and build your app, and take longer than just a Gradle sync
To see all available gradle task, use ./gradlew tasks

In Android Studio 3.3 it is here:
According to the answer https://stackoverflow.com/a/49576954/2914140 in Android Studio 3.1 it is here:
This command is moved to File > Sync Project with Gradle Files.

Keyboard shortcut lovers can add a shortcut for running gradle sync manually by going to File -> Settings -> Keymap -> Plugins -> Android Support -> Sync Project with gradle files (Right click on it to add keyboard shortcut) -> Apply -> OK and you are done. Choose any convenient key as your gradle sync shortcut which doesnot conflict with any other shortcut key, (I have choosen Shift + 5 as my gradle sync key), so next when you want to run gradle sync manually just press this keyboard shortcut key.

I presume it is referring to Tools > Android > "Sync Project with Gradle Files" from the Android Studio main menu.

gradle --recompile-scripts
seems to do a sync without building anything.
you can enable automatic building by
gradle --recompile-scripts --continuous
Please refer the docs for more info:
https://docs.gradle.org/current/userguide/gradle_command_line.html

Shortcut (Ubuntu, Windows):
Ctrl + F5
Will sync the project with Gradle files.

I think ./gradlew tasks is same with Android studio sync. Why? I will explain it.
I meet a problem when I test jacoco coverage report. When I run ./gradlew clean :Test:testDebugUnitTest in command line directly , error appear.
Error opening zip file or JAR manifest missing : build/tmp/expandedArchives/org.jacoco.agent-0.8.2.jar_5bdiis3s7lm1rcnv0gawjjfxc/jacocoagent.jar
However, if I click android studio sync firstly , it runs OK. Because the build/../jacocoagent.jar appear naturally.
I dont know why, maybe there is bug in jacoco plugin. Unit I find running .gradlew tasks makes the jar appear as well. So I can get the same result in gralde script.
Besides, gradle --recompile-scripts does not work for the problem.

I have a trouble may proof gradlew clean is not equal to ADT build clean. And Now I am struggling to get it fixed.
Here is what I got:
I set a configProductID=11111 from my gradle.properties, from my build.gradle, I add
resValue "string", "ProductID", configProductID
If I do a build clean from ADT, the resource R.string.ProductID can be generated. Then I can do bellow command successfully.
gradlew assembleDebug
But, as I am trying to setup build server, I don't want help from ADT IDE, so I need to avoid using ADT build clean. Here comes my problem.
Now I change my resource name from "ProductID" to "myProductID", I do:
gradlew clean
I get error
PS D:\work\wctposdemo> .\gradlew.bat clean
FAILURE: Build failed with an exception.
* Where:
Build file 'D:\work\wctposdemo\app\build.gradle'
* What went wrong:
Could not compile build file 'D:\work\wctposdemo\app\build.gradle'.
> startup failed:
General error during semantic analysis: Unsupported class file major version 57
If I try with:
.\gradlew.bat --recompile-scripts
I just get error of
Unknown command-line option '--recompile-scripts'.

Anyone wants to use command line to sync projects with gradle files, please note:
Since Gradle 5.0,
The --recompile-scripts command-line option has been removed.

From terminal:
gradle prepareKotlinBuildScriptModel
NOTE: you can see what android studio is doing by inspecting the "Build" tab. There will be difference windows inside there. One should be "Sync"
