ok, after fighting for 2 days, TeamCity is back working fine. http://teamcity.xwiki.org We had a disk full problem dues to the large size of our maven repos so I cleaned them all and then discovered the build on TC wasn't working anymore. This was due to several errors in the build which were hidden by the fact that the local repo on the TC machine had the artifacts there. To be more precise, in order to do a release with maven we cannot have any SNAPSHOT deps in our POM so we had to "release" some external dependencies we're using in SNAPSHOT version. One of these was the maven selenium plugin and I've discovered that faking a release of an external maven plugin isn't as simple as it appears... But I now know how to do that. Thanks -Vincent
