My RCP app was using http://pydev.org/updates for PyDev, which was
upgraded yesterday (I think) from PyDev 4.4 to 4.5. I'm using 4.4 now
after switching to https://dl.bintray.com/fabioz/pydev/all/, but I'd
like to run with 4.5, and I have a problem with it.
When I launch the app, the console gets flooded with numerous instances
of the stack trace below. The line of my code that leads to the
exception (MidasActivator line 339) is this
IInterpreterManager manager = ...
manager.setInfos(new IInterpreterInfo[] {xmpyInterp}, null, new
NullProgressMonitor());
I'm updating the python interpreter there after adding a pypredef location.
This doesn't happen in PyDev 4.4. Also it doesn't happen in PyDev 4.5 if
I omit the com.python.pydev plug-ins from my product (specifically
com.python.pydev.analysis). In that case, I get an NPE when PyDev checks
if the interpreters are synced with the environment. I can prevent that
exception my implementing a contribution to extension
org.python.pydev.pydev_interpreter_info_builder which does nothing.
So I don't know if I've got something in my code that is incompatible
with PyDev 4.5, or is implementing an info builder extension that does
nothing the expected pattern? I would think that including the
com.python.pydev plug-ins is expected, in whch case I need to figure out
why I get exceptions when I do.
