Access source bundles for unpacked plugins with a code-jar [message #1689858] Tue, 24 March 2015 09:56 Go to next message

I'm integrating PyDev into an RCP product and hence am frequently accessing PyDev's classes. I do have source bundles generated by tycho for PyDev and they are part of the target platform but unfortunately Eclipse does not pick them up automatically like it does for other plugins (like the eclipse base plugins for rcp apps).

The PyDev plugins are a little special in that they are set to be unpacked when installed into an Eclipse instance (and this works fine) since they contain python source code that is being accessed when using PyDev by a python process. At the same time these plugins have all their actual java class files inside another jar thats placed inside the plugin jar. Again there's no issue using or loading this when using the final product or starting a launch config, but I think this somehow breaks Eclipse source-lookup feature.

I'm wondering wether there's something in the plugins metadata or a setting in Eclipse to help it figure out that the source bundles are meant to be set as source-location for the jar's inside the PyDev plugins?

I don't know about the underlying details of the mapping (I'd suggest opening a bug against PDE), but you can explicitly set the source location for a jar from its properties:



  1. Open the project
  2. Navigate to the jar (e.g., Plug-in Dependencies)
  3. Right click and choose Properties and go to the Java Source Attachment

Yeah thats my workaround for now, but its quite tedious to do this on multiple machines and for multiple plugins. Not to mention that we do update the plugins from time to time which means the mapping is gone again.

Given the lack of reply on another PDE bug I filed I thought I'd try here first in the hope that the forum has a bigger crowd of knowledgable people than the people reading PDE bugreports.

What's the bug number?

The bug I filed is also related to the PyDev plugins and the way they are packaged, PDE does not seem to fully unpack the plugin when launching an RCP application from inside Eclipse:
