How to add additional classpaths / libraries?

[LuFlo]

Is there a possibility to add additional classpaths, for example if I want to use external libraries? I now someone asked a similar question and the issue was closed, because we should ask the language server guys. But it should exist a possibility to forward arguments to the actual server from within the UI (not only JVM arguments). Also it would be awesome to set different classpaths for different projects :-)

Any ideas? :-)

Maybe adding in the .classpath file

Indeed it was able to do it by altering the .classpath file. However it would be still awesome if there was a way to do it inside the IDE (similar to Netbeans, etc...)
