Description
Hello,
One of our Maven2 projects started to fail on Continuum. When I checked the Builds page, there were always pairs of entries with a few seconds between them. For each of these pairs of build results, the former was always in Error, while the latter (most recent build) was always in Failure.
The log of the error build was this:

If I look at the Working copy, there is no pom.xml file, so I was quite puzzled. The CVS repository does contain the pom.xml and a checkout of the project to my local workstation was completely OK.
I finally found the error in the wrapper.log. The POM used a property to resolve a dependency version that was undefined in the parent pom, leading to validation errors. This error message should definitely end up in the Output textfield of a Build results page in the webfrontend!!!

INFO | jvm 1 | 2008/06/24 08:35:31 | 'dependencies.dependency.version' is missing for be.telenet:srv.location.location
Another remark: having two entries in the Build results page for a build I triggered once made me believe that there were two copies of Continuum running, with the error coming from concurrent access of the working copy. A build failure should only end up in one build result...
