Hi, all.
I'm writing a custom ClasspathContainer to manage project dependencies
defined in custom configuration files. I parse those files, resolve the
dependencies, and add them to the container. So far, so good.
My current problem is that some of those dependencies (.jars) are stored
in .tar archives.
Now, I can access those archived jars directly using some 3rd party
library, or even load the actual classes using Apache Commons
VFSClassLoader, but I can't think of a way to add them as entries to my
ClasspathContainer (apart from trying to override the classloader used
by JDT, which scares me a bit and probably isn't even possible).
Extracting those files in some folder inside my plugin state area could
be a workaround, of course, but what I'd like to know is: can the
desired behaviour be achieved through JDT APIs?
Any suggestion is welcome...
Thanks in advance,
Angelo

Any thoughts? Even a "you can't do it" would give relief to my sleepless
nights... ;-)

Sorry, nested jars are supported neither by JDT nor by the Platform.

Whoops. I was vaguely aware of that since reading bug 157375
<https://bugs.eclipse.org/bugs/show_bug.cgi?id=157375#c19> some time
ago, but I didn't realize that mine was a similar use case.
Thanks for the clarification.
