GEP: NullPointerException when deploying project

[Gert Vanthienen]

L.S.,

When I use GEP 2.1.0 with Ganymede RC4 and try to publish a webapp to Geronimo 2.1.1, I get the exception below.  Did I miss something up or is this a known bug?

Regards,

Gert

Jacek also reported an NPE with Ganymede RC4.  2.1.1 is target
for/supported on Europa Winter.  After 2.1.1 is released in a couple
days, we'll start work on Ganymede support in trunk.

There is a rudimentary set of install instructions available at the
URL below that will hopefully describe the necessary prereq(s) and
steps required to install and run the GEP 2.1.1 on Eclipse Europa
Winter:

"A known bug" is that Eclipse Ganymede is not on the list of supported
platforms for GEP :( We, Ganymede users, have to wait a little longer
until it's fixed. Ganymede RC3 worked fine with GEP 2.1.1, but RC4
broke it.
