[ https://issues.jboss.org/browse/JBIDE-16743?page=com.atlassian.jira.plugi... ] Fred Bricon commented on JBIDE-16743: ------------------------------------- I believe this is caused by https://github.com/jbosstools/jbosstools-central/commit/dcd07cb8ca0b716fd... (see JBIDE-14990, fixed in 4.1.0) Basically, if it's a Maven project, we ignore source lookup to let m2e do its thing, so as to not have 2 competing source lookup mechanisms for the same file. On top of my head, I'd say we need a more fine-grained solution, where we check if it's a jar from the Maven Library. I haven't debugged the problem, so I'm probably missing something. -- This message is automatically generated by JIRA.
