REST Android Client using Spring and OAuth2 Error DexArchiveMergerException: Unable to merge dex

I have a server running and I want to connect an android client to the server with spring's oauth2. I use Android Studio. My problem is related to the gradle configurations, which I don't know how it should be.
Problem: When I run the app, I get this error:
Error:Execution failed for task':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.> com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex
I have seen many other questions with the same problem, I tried the solutions (like adding multiDexEnabled true, clean and rebuild the project etc.) but none of them worked. I think that the problem is caused because these two dependencies:
implementation 'org.springframework.security.oauth:spring-security-oauth2:2.2.0.RELEASE'
implementation 'org.springframework.android:spring-android-rest-template:1.0.1.RELEASE'
might have some common jars or something. Any help would be appreciated.

Try this it should work for your cause. Go through this link to understand why we should add this line of code multiDexEnabled true

I finally solved the problem. There were two modules that were duplicate, so I had to exclude them from the Module build.gradle file. What I had to do was:
compile('org.springframework.android:spring-android-rest-template:2.0.0.M3') {
exclude module: 'spring-android-core'
}
compile('org.springframework.security.oauth:spring-security-oauth2:2.3.0.RC1'){
exclude module: 'spring-web'
}

app:transformClassesWithJarMergingForDebug'. > com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry

Please need your help...
this my app build.gradle

How I can remove this error ?

You should add this in your build.gradle section
META-INF directory are recognized and interpreted by the Java 2
Platform to configure applications, extensions;
packagingOptions {
exclude 'META-INF/DEPENDENCIES'
exclude 'META-INF/NOTICE'
exclude 'META-INF/LICENSE'
}
Then Clean-Rebuild-Run
