Cannot create library: javac-api of unknown type: j2se
I also see a similar for messages for jaxb, MySQLDriver, PostgressSQLDriver at start up.
this may be related to issue 156658... If there is link between the this and 156658, please let me know.
I was able to reproduce this with a recently pulled build.
I was able to make these messages 'go away' by removing the ergonomics code (by right-click 'Clean' on the project) from
the built IDE.
This message appears because ide cluster has runtime dependencies on java cluster which is not enabled. E.g. it
registers java libraries which are only handled when the java cluster is enabled. The message is correct and harmless
(lowering priority). The behaviour is OK, as soon as you enable Java cluster: as such I suggest "won't fix".
