NullPointerException when loading project file with maven2 plugin

hi

i use the maven2 soapui plugin as indicated on http://www.soapui.org/plugin/maven2/index.html. when i execute maven, it complains about a null pointer exception.
the project contains a rest resource and one test case which makes a simple http get request.

please note:
- i do not use attachments.
- the file is at the correct location
- please find the maven config, the project file and the resulting exception stack strace below.

any help is appreciated.

regards,
christian abegg
