Running Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'

Question

Running Error Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'
So I'm continuously receiving a gradle build error upon trying to run my project. I have searched for other solutions and some say that adding:

packagingOptions {
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE' // will not include LICENSE file
    // as noted by @Vishnuvathsan you may also need to include
    // variations on the file name. It depends on your dependencies.
    // Some other common variations on notice and license file names
    exclude 'META-INF/notice'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license'
    exclude 'META-INF/license.txt'
}

But it doesn't work for me.The Error as below: Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.

com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/rxjava.properties

**File1: E:\Workspace_Android\TravelStory\app\build\intermediates\exploded-aar\cn.bmob.android\bmob-sdk\3.5.0\jars\classes.jar

I try to delete the File2 but after compile/gradle the file created again.
studio version is 2.2.3
gradle version is 2.2.3

My gradle file content as below:

Answer 1

Your not excluding the file the error is warning about.

com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/rxjava.properties

Here the complaint is META-INF/rxjava.properties so just update your packageOptions block to exclude this file explicitly.

packagingOptions {
    exclude 'META-INF/rxjava.properties'
    // ... and any other excludes go here
}

Answer 2

Update your gradle with this code:

packagingOptions {
        exclude 'META-INF/DEPENDENCIES.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
    }

This happens when there is a duplication of libraries
