Sonar-erlang verion 1.4 is not compatible with sonarqube developer version 9.6

[sisihlia]

Hello

I am trying to work with sonar-erlang version 1.4 The version of sonarqube installed is developer 9.6. I’ve downloaded the jar and put it in $SONARQUBE_HOME/extensions/plugins. But the sonarqube failed to start as below error

Is there compatibility issue it is stated that the plugin has been tested to work with SonarQube Community Version 8.9.0 ?
