sonarqube restart failed after install the plugin

[daikaixian]

It's sonarqube-6.2.
And I put the jar in the $SONARQUBE_HOME/extensions/plugins directory
then Copy run-sonar.sh somewhere in my PATH
but Restart the SonarQube server FAILED!!!

No log show the reason, just tell me that Process[es] is stopping,Process[web] failed to start,Process[es] is stopped.

Anyone know how to fix?
THX.

same problem! I'm using sonarqube-6.1.
I've tried many times, sonar start will permanently fail, as long as I put jar under $SONARQUBE_HOME/extensions/plugins, I'll have to reinstall sonarqube again.

@BevisssLiu I know the problem .
It's because the newest sonar-objective-c.jar not support sonarqube-6.x.
Only 5.x and other older version sonarqube was supported.

is there any objective c plugin that works with sonarQube 7.0?
