Firstly, since development has been moved to
eclipse.org, please consider using the newsgroup instead (web access at
http://www.eclipse.org/newsportal/thread.php?group=eclipse.technology.iam)
Now to the important bits...
You can set up a Run configuration (Run > instead and save it (it can be saved with the proyect so all the developers can reuse it).
Run > Run configurations... > double click Maven 2 > configure your maven launch
Another option would be to setup maven as an external tool. This bypasses IAM and allows you to run a locally installed maven in a new process (which means that, if the goal changes resources, you must refresh your project after running the goal):
Run > External tools > External Toools Configurations...
