NullPointerException for org.codehaus.gmaven:groovy-maven-plugin:2.1

Hello everyone! I have an issue with library I think, it happens after I try to do mvn package. I already tried to delete everything from .m2 folder, Invalidate caches in Idea and install everything again

That's an error: [ERROR] Failed to execute goal org.codehaus.gmaven:groovy-maven-plugin:2.1:execute (default) on project RacetracMobileTFA: Execution default of goal org.codehaus.gmaven:groovy-maven-plugin:2.1:execute failed.: NullPointerException -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch. [ERROR] Re-run Maven using the -X switch to enable full debug logging. [ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/PluginExecutionException

And that's pom file:

            </plugin>
