IDEA not finding JavaDoc
Answered
For some reason, I can't get IDEA to display JavaDoc for some libraries. I have IDEA configured to download JavaDocs and as you can see on the screenshot below, they are indeed downloaded. However, when I press Shift+F1 on a class from spark-sql, nothing happens. For some other libraries it works fine and it opens the docs in my browser.
Any ideas what could be the reason why JavaDoc is not working for spark?

Look inside the jar and compare it to the other working jars. It could be the the jar is packaged incorrectly or is missing some files. In this case you should contact the library vendor so that they can fix it and upload the new version to the Maven repository.
Looking into the JAR file, I see that it's not in the typical layout used by Java projects, but the one that Scala docs use. So I guess that's the problem. Is there any plugin that I could install to get support for Scala docs?
I'm not aware of that. I guess all the Maven jar libraries should follow JavaDoc standard.
