I am using the crap4j hudson plugin in one of my projects. The ant build puts
the report.xml into a directory like "(Projektname Build)/dist/crapreport/". I
tried to configure the plugin to look in that directory but it did not find the
report. When I changed the build-file to put the report into the workspace root
and configured accordingly it worked flawlessly. So I suspect that the blanks
and/or the braces cause problems here.

A workaround for me is to specify the report location as "**/crapreport/report.xml".
