A post on Nabble Maven Users (http://www.nabble.com/core-api-container-outdated-on-snapshot-repository-tf2550173.html#a7110351) has given a brilliant idea for Bamboo.

For those who run on maven projects, It would be a great feature for successful nightly builds to automatically deploy to the remote repository. The build process would be something like this:

External:
(1) SVN/CVS commit new changes

Bamboo:
(2) Builds triggered, builds
(3) IF (successful build) && (maven II project) THEN run 'mvn deploy'

Some prerequisites for doing this are:
1. pom.xml must have distribution managment setup
2. bamboo server must have settings.xml setup with authentication settings.

I'm sure the guys at cargo codehaus would love you for this
