I'm trying to build Google Go from their Google Code Mercurial repository.

https://go.googlecode.com/hg

Configuration attached.

Every week or so, they tag a new release. I then update my Hudson configuration to put something like "release.2010-10-20" as the branch (full config attached).

However, when I build the project, the Mercurial plugin doesn't ever do a pull, so it doesn't find the new tag.

The polling log:
