ExtensionRegistry does not recognize PythonNature code

[Florian Shkurti]

Hi everyone,

I am facing a very weird problem while trying to create an Eclipse fragment
project that depends on the plugins org.python.pydev and org.python.pydev.core:

I have a main Eclipse plugin and two fragment projects that add optional
functionality to the plugin. Each of the fragments has only one source
file, which adds a nature to a given IProject. The first fragment adds the
C nature and the second fragment adds the Python nature (via PythonNature.addNature()).
The two fragments also extend an extension point defined in the main plugin.
 
Here's the weird part: the two fragments are almost identical (their ids are different of
course) but only the C fragment is recognized at runtime as an extension of said extension
point, while the Python fragment is not. I see this via Platform.getExtensionRegistry().getExtensionPoint(...).getExtensions()

I believe the extension point is defined correctly in the main plugin
and the two fragments also extend it correctly. The weirdest part is that
when I comment out PythonNature.addNature() in the Python fragment
(and I also remove the dependencies on org.python.pydev and
org.python.pydev.core) the Python fragment *is* recognized by the extension registry.

This leads me to believe that for some reason including code from org.python.pydev
and org.python.pydev.core in an extension makes it "invalid". Can anyone help me find
a way to correct this? Let me know if you need some actual code.

Thanks in advance,
Florian

Has your python fragment correct dependency on pydev plugins? When I
was developing against CVS checkout and added version requirement like
org.python.pydev; version > 1.3.17 I had to update MANIFEST.MF that
contains some obsolete number and is only replaced during release
build.

Did you check .log file for warnings and message if there is something
suspicious?
