@JBL_SonarSource Thanks for your quick reply.
I’ll check the class path again, but I already did so (and a colleague has the same problem).
We’re currently still using Java 8 for development purposes, so there should be no Java 11 compiler or runtime yet involved. Using the IntelliJ version that has Java 11 included seemed to be ok, as it is only used by IntelliJ internally.
Concerning the plugins: Our Sonar server does not offer the update any newer ones (I recently updated the plugins and checked again today), especially not the update of the plugin version supporting Java 11. I suppose this is due to the fact that the Sonar server version we’re currently using does not support newer plugins, or do I miss something here?
We’d definitely like to upgrade to the current version, but as this requires migrating the database from MySQL to most probably Postgress, this will take some time.
Thanks for your help and Sonar as a great tool.
