We've specified an addition Maven 2-type builder pointing to the Maven 2.0.5 installation on our server. Maven 2.0.4 failed to resolve dependencies properly in a complex build resulting in the dependency being excluded at all. This produced compilation errors (e.g. in JMS transport module in our case).

Upgrading to Maven 2.0.5 fixed the problem and it works fine from the command line and for our current build on the Luntbuild server. However, Bamboo still seems to be using an older maven version failing to compile the module. I have confirmed the plan is using maven 2.0.5.

The error can be reproduced at http://svn.codehaus.org/mule/trunk/mule/ as of r5398 , the JMS transport will be the first to fail the compilation when run from the root of the project.
