Extending source lookup [message #893480]

Hello,

I'm trying to build the plugin that extends the source-lookup flow for Java projects. I want to start with hello-world style project that will display some fake Java source whenever the user "steps into" the class that doesn't have attached sources (or for every class at all). This would be the first step before displaying the actual source code.

Should I use eclipse org.eclipse.debug.core extension points for that? I tried to hook into both
org.eclipse.debug.core.sourceContainerTypes and org.eclipse.debug.core.sourceLocators, but the classes I provide are never got called.

I am somewhat confused what approach should I take to attach custom logic to the Java sources lookup flow. Any help is highly appreciated.

P.S. If you're curious why do I need that - the sources for some classes of my project are generated and compiled at runtime. They are accessible through the classloader, but they do not physically exist in a form of JAR or in folder in a workspace.

Try looking at ISourceLookupParticipant and ISourceLookupDirector (specifically the JavaSourceLookupDirector). It sound to me like you would want to add your own participant to the Java director, which you can do by calling ISourceLookupDirector #addParticipants(...).

To get the Java director you have to a bit more work, you will need to get the ILaunch from the frame (thread, etc) and ask for its ISourceLocator (in the Java case it is an ISourceLookupDirector). You would probably want to attach your participant to any new and existing Java launches, which you can do with the help of the ILaunchManager.
