SonarQube 9.0 fails to load sonar-groovy with NoClassDefFoundError: org/sonar/api/profiles/ProfileDefinition

After upgrading to SonarQube 9.0 i had to remove the sonar-groovy plugin because of the following error during startup:

Had version 1.6 installed and also tried it with 1.7. Let me know if I can help..?

Saw in the changelog that they removed many deprecated classes, so I'm not really surprised...

@boardend Do you want to try a test build from #67? That change seems to fix the issue...

With sonar-groovy-plugin-1.8-SNAPSHOT.jar from Github SonarQube 9.0 is able to start again. Thank you!

@boardend Thanks. I'll try to get a release out sometimes soon!
