hi all,
since i imported the SDKBOX Plugin (and installed iap) i can’t make gradle update or install the libraries.
it says:
proj.android-studio xxx$ gradle install
FAILURE: Build failed with an exception.
* Where:
Build file '/Users/xxx/cocos2d/cocos/platform/android/java/libs/gps/build.gradle' line: 1
* What went wrong:
A problem occurred evaluating project ':gps'.
> Could not create plugin of type 'LibraryPlugin'.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED
do you know how to fix it? i’m using cocos2dx v3.11. i did not touch any property files or even the manifest so the project has no modifications from my side. updating the SDKBOX did not work. please help since i hate copy-paste libraries i want to use 
thanks!
