All of a sudden my builds have started to fail. I've tracked it down to the site goal being in build. If I move the goal to Post Steps, it works just fine. I get an error, but it isn't at all useful. This happens with Maven 2.2.1, 3.0.3, and 3.0.4. It just started today, builds from yesterday are fine. This is happening with jobs that haven't had anything change in months. I am a bit out of date with version for Jenkins, but that wouldn't explain why this started happening all of a sudden. My guess is that it is the archiving action of calling the site goal in the Build section. Blowing away site and javadoc directories, I do get the site directory again on a build attempt, but not javadoc. Copying the project configuration of a project with problems results in a successful build.
