FAILURE: Build failed with an exception.

- What went wrong:  
Execution failed for task ':plugins-lang-groovy:compileTestGroovy'.  
Cause: Forked groovyc returned error code: 1

- Try:  
Run with --stacktrace option to get the stack trace. Run with --info  
or --debug option to get more log output.

BUILD FAILED

can anyone suggest me how to overcome those exceptions

Thanq
