Hi all,
I'm trying to extend a plug-in that works with my company's Eclipse v3.2
base. Before writing any new code, I'm trying to verify my build
environment setup.
I created a plug-in using Ganymede, v3.4, from the existing jar and
rebuilt it, then exported it. I set all the dependencies to the jars we
ship with our product, which are all v3.2 based. I can get our product to
load and resolve the new jar just fine. However, when I access any part
of the code in the jar (i.e. preference page, etc.) Eclipse pops up errors
about null pointer exceptions. Remember, I haven't touched a line of
working code.
I went through my jar and the original jar and my newly compiled classes
are all a little bigger (100-200 bytes) than the originals.
If I remove my version and replace the original version everything is back
to normal, so it's definitely something in my jar, although it
compiles,exports, and resolves successfully.
Am I running into a versioning issue? Should I be compiling with a
certain version of the compiler with certain compatibility flags set? All
I want to do at this point is rebuild some working code. Once I can
reliably do that I'll know any new problems are MY doing ;-).
Thanks in advance for any insights.
Rgds,
Bret
