When using maven convention, a library is bundled as ‘group.artifact.version.jar’ for binary, ‘group.artifact.version-sources.jar’ for source code and ‘group.artifact.version-javadoc.jar’ for docs. If you don’t see the javadoc, then it means that the ‘-javadoc.jar’ for that artifact is not pulled to local, in your case for the akka artifact. If you right click on the library, you should find an option to download javadoc under ‘Maven’ option. Once you download, you can see the javadoc.
