How to solve the problem with converting Java classes into dex format, Unity - GPG Plugin?

Question

Java

Hello, I'm trying to connect the GooglePlayGames Plugin, but getting rid of one problem knocks out another. Now it does not allow compiling the apk and knocks out such errors:
The code is identical.

id-sdk\tools" -Dfile.encoding=UTF8 -jar "C:\Program Files\Unity\Editor\Data\PlaybackEngines\AndroidPlayer/Tools\sdktools.jar" -

stderr[

Help, how to be in this situation, what could I do wrong?

You have a duplicate method. somewhere in the project there is another plugin/library with the same method. Something for GSM, push some.
As an option to the extreme (if there are no ideas what else Google services can partially contain) - delete jar files one at a time until the culprit is found
