org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:transformClassesWithDexForDebug'

Due to 65K error in my project I need it to migrate to Android Studio . While running

> ./gradlew assembleDebug

I am getting the error:

Execution failed for task ':app:transformClassesWithDexForDebug'.
com.android.build.api.transform.TransformException:
com.android.ide.common.process.ProcessException:
java.util.concurrent.ExecutionException: 
com.android.ide.common.process.ProcessException: 
org.gradle.process.internal.ExecException: 
Process 'command '/opt/jdk/jdk1.8.0_45/bin/java'' finished with non-zero exit value 1

I know this is very common error which all get while migrating an Eclipse project to Android Studio.

I tried every solution, I tried to add .jar files one by one in my project, I used only those Google-services packages which are getting used in my project, I even added multidex jar.But nothing helps me

Where am I going wrong?

Check build.gradle(Module: Android) fixed problem for me.

Modify it to workable version.

android {
    buildToolsVersion '23.0.1'
}

Just a simple solution is here...it worked for me:

1. Clean Project
2. Rebuild project
3. Sync project with gradle file

the steps I followed are:

1. close Android Studio (or IntelliJ IDEA)
2. in your project's directory:
3. delete .idea directory
4. delete .gradle directory
5. delete all .iml files

• find . | grep -e .iml$ | xargs rm

1. use Android Studio to re-open the directory as a project

Terminal commands:

# close Android Studio
cd "your project's directory"
rm -rf ./.idea
rm -rf ./.gradle
find . | grep -e .iml$ | xargs rm
# use Android Studio to re-open the directory as a project

I had the same issue and I could solve it like this:

1. If your minSdkVersion is set to 21 or a higher value, the only thing you need to do is to set multiDexEnabled in your build.gradle file at the module level, as shown below:

   android { defaultConfig { ... minSdkVersion 21 targetSdkVersion 28 multiDexEnabled true } ... }

2. However, if your minSdkVersion is set to 20 or less, you should use the MultiDex compatibility library, as follows:

2.1) Modify the module-level build.gradle file to enable MultiDex and add the MultiDex library as dependency, as shown below

android {
    defaultConfig {
        ...
        minSdkVersion 15 
        targetSdkVersion 28
        multiDexEnabled true
    }
    ...
}

dependencies {
  implementation 'com.android.support:multidex:1.0.3'
}

2.2) According to the Application class or not, do one of the following actions:

2.2.1) If you do not cancel the Application class, modify your manifest file to set android: name in the <application> tag as shown below:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapp">
    <application
            android:name="android.support.multidex.MultiDexApplication" >
        ...
    </application>
</manifest>

2.2.2) If you cancel the Application class, you must change it to extend MultiDexApplication (if possible) as shown below:

public class MyApplication extends MultiDexApplication { ... }

2.2.3) Also, if you override the Application class and can not change the base class, alternatively you can override the attachBaseContext () method and invoke MultiDex.install (this) to enable MultiDex:

public class MyApplication extends SomeOtherApplication {
  @Override
  protected void attachBaseContext(Context base) {
     super.attachBaseContext(base);
     MultiDex.install(this);
  }
}

Please use this link, it was really useful for me!

Try to move:

apply plugin: 'com.google.gms.google-services'

just below:

apply plugin: 'com.android.application'

In your module Gradle file, then make sure all Google service's have the version 9.0.0.

Make sure that only this build tools is used:

classpath 'com.android.tools.build:gradle:2.1.0'

Make sure in gradle-wrapper.properties:

distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip

After all above is correct, then make menu File -> Invalidate caches and restart.

I have been struggling with this problem for 2 days. And tried all options. Finally noticed that after updating my android studio, it was not showing me the compile errors like @v.d. wrote above. My problem was, In my build files, I was using compile(which should be replaced with implementation or api) and testcompile(which also replaced by testimplementation). Notice that I have changed in whole build files(android, app and others - in my case I also had folding-cell library)

for example instead of this

compile project(path: ':folding-cell')

write this

implementation project(path: ':folding-cell')

your manifest application name should contain application class name. Like

<application
        android:name="your package name.MyApplication"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:theme="@style/AppTheme"> 

for me it was just a little compile error and sadly Android Studio doesn't show it . please search manually . trying to enable work offline and clean&rebuild may help you more

Its Just Simple the Compiler Did not accept the last changes you've made so go to the last file that you've made a change It will show the error just change it and recompile.

Just remove this line from build.gradle(Project folder)

apply plugin: 'com.google.gms.google-services'

Now rebuild the application. works fine Happy coding

Apply in ProGuard-rules

-ignorewarnings

My Simple Answer is and only solution...

Please Check The layout files, which you added lastly there MUST be a error in the .xml file for sure.

We may simply copy and pasting .xml file from other project and something missing in the xml file..

Error in the .xml file would be some of the below....

1. Something missing in Drawable folder or String.xml Or Dimen.xml...

After Placing all the available code in the respected folders do not forget to CLEAN The Project...

I have disabled Instant Run feature from the preferences and the issue was solved.

delete intermediates folder from app\build\intermediates. then rebuild the project. it will work

For me the only thing that works is to add to repositories

maven {
        url "https://maven.google.com"
    }

It should look like this:

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }

For my case, I follow the steps from Firebase and by mistake I pated it in a wrong file.

Then, I returned to the project from Project to Android. Once in the Android view I pasted the file /projectname/app/YOUR-FILE-HERE and now, you have to compile again.

you just change import android.support.v7.app.ActionBarActivity; to import android.support.v7.app.AppCompatActivity;

and extends AppCompatActivity

Well in my case i was accessing an static array of a class by reference of that class, but as we know we can directly access static member via class name. So when I replaced reference with class name where I was accessing that array. It fixed this error.

Add multiDexEnabled true to your app-level Gradle, like this:

defaultConfig {
    multiDexEnabled true
    ...
}

Migrate to androidX library

With Android Studio 3.2 and higher, you can migrate an existing project to AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar.

Source: https://developer.android.com/jetpack/androidx/migrate

clear project and then run. it will work

If anyone is facing a similar type of error while adding ShimmerRecyclerView Loader, make sure to add: maven { url "https://jitpack.io" } under allprojects in your app-level Gradle, like below:

allprojects {
    repositories {
        google()
        jcenter()
        // Add it here
        maven { url "https://jitpack.io" }
    }
}

In my case, I am also facing this types of error while run the project in Android Studio. It may be facing this types of error due to dependencies need to be upgrade with higher evrsion.

I have used below dependencies

> implementation 'jp.wasabeef:glide-transformations:3.3.0'

Now changed with upgraded version as below

> implementation 'jp.wasabeef:glide-transformations:4.3.0' > Now sync the build.gradle then run the app is successfully.

for me, it was the missing Manifest file that was to blame. I created a new module and forgot to add Manifest

first you remove this thing in your project .. its is in build.gradle(module:app) then build your app now you project show the actual error and you find what is your actual problem is .. and after you find actual problem again paste it where its is belong to

allprojects { gradle.projectsEvaluated {

    tasks.withType(JavaCompile)

{ options.encoding = 'UTF-8'

        options.compilerArgs

<< "-Xlint:unchecked" << "-Xlint:deprecation"}]}}
