Code that was compiling in 3.3.2 doesn't compile in 3.4 [message #329636] Mon, 30 June 2008 18:16 Go to next message

I'm working with a target platform of about 700 plug-ins.
When I create a new plug-in in Eclipse 3.3.2 that depends on some of those
plug-ins every thing works fine.
In Eclipse 3.4, on the other hand, I'm getting a lot of duplicate JARs
under the plug-ins dependencies library. That, of course, causes the code
not to compile with the following error (this is one example):
Cannot nest 'C:Program
Files/IBM/Director/lwi/runtime/USMiMain/eclipse/plugins/com. tivoli.twg.libs_1.0.0/classes'
inside library 'C:Program
Files/IBM/Director/lwi/runtime/USMiMain/eclipse/plugins/com. tivoli.twg.libs_1.0.0'

Are you able to reproduce this in a way that would let someone work on it?

Have you found anything useful in Bugzilla?

It's happening for me on all the plug-ins in my workspace (7).
I searched a lot in Bugzilla without success. I thought of opening a
defect on this because I can't work with 3.4 at all :(

By any chance, are you using link files? If so, check if there aren't
duplicate link files pointing to duplicate directories.

Cheers,

"Happening for you on all your plugins" is, sadly, not the same as
"reproducible in a way that others can work on". For a bug report to be
useful, it is not enough to report the problem, you need to find steps that
can let someone else reproduce it. This may be easy, or it may be hard -
ironically, most of the "it doesn't work at all" cases are hard to
reproduce, because obviously for the vast majority of users it *does* work.

If you can start with a fresh workspace and try to figure out the minimal
steps that need to be done to make it show the problem you're experiencing,
that will help. Without that there's not much anyone can do other than be
sympathetic.

Or, hopefully Chris' response will be all you need.

Please take a loop at this screenshot, from Eclipse 3.4:
http://i29.tinypic.com/25g9gys.jpg
All the red boxes represent folders that don't appear in Eclipse 3.3.2.
All those folders contain JAR files that already appear in the list. That
is causing a duplication of those JARs, as is shown by the two red arrows.

No, I don't.

This looks like a PDE container problem. I suggest to file a bug report
against PDE. If you can't find reproducible steps then you might send
your workspace to one of the developers looking at the bug.

I managed to reproduce this bug in a minimal workspace.
I opened the following bug on this problem:
