I would like to have the javadoc comments contained in a jar file show

  • 0

I would like to have the javadoc comments contained in a jar file show in eclipse when I hover over a class.

For example, after downloading JODA-2.0, three jars are obtained:

In eclipse, [right click project -> Properties -> Java Build Path -> Libraries -> ADD JARs…] includes the binary in the project (can reference those classes) for joda-time-2.0.jar.

But how can I link in the sources/javadoc comments contained in the other two jar files so that when I hover over those classes I see the javadocs?

Adding the other two jars (joda-time-2.0-javadoc.jar and joda-time-2.0-sources.jar) to the build path does not link the javadocs or the source.

    You can try to CTRL + click on a class that has no source attached (do that in editor). When it shows you some info about the class you’ll see the button that guides to attach source dialog. Click it and in dialog that pops up pick the source/javadoc location for your class.

    You can also do that from project build path settings you are mentioning: pick libraries tab, expand the library (jar) you want and you’ll be offered to pick: source attachment, javadoc attachment, native library location, etc. You just pick whatever you want and edit its current settings.

    Or you can do as @JB Nizet said…
