Unity Game error after adding new plugins

Question

Im trying to implement GameAnalytics Plugin into my game. Also, im using AdInCube plugin, which works fine, but now i get an error every time during build. I received exactly the same error when i tried to implement Google Play Services plugin. Problems occur just after the import new package, without any changes in code. I tried to use AndroidManifests from both plugins, but i got this error anyway.

Error:

CommandInvokationFailure: Gradle build failed. 
C:/Program Files/Java/jdk1.8.0_191\bin\java.exe -classpath "C:\Program Files\Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-4.2.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx2048m" "assembleRelease"

stderr[

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':transformClassesWithJarMergingForRelease'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/auth/api/signin/GoogleSignInAccount.class

I discovered that Unity creates two the same folders during building and therefore doesnt know which one to use. I cant just delete one of them, because it will be created anew immediately. I have no idea which files you need to help me, so ill add this for now.
