I have Maven project with dependencies in repo and stuff. I want to \"export\" its sources with all dependencies so that I can successfully open it in IDE without Maven runn
Actually, there is nothing that will create a bundle with sources and dependencies out of the box. For this, you'll need to use a combination of the some plugins.
For dependencies, the Maven 2 Dependency Plugin and its copy-dependencies will help as pointed out by cetnar.
For sources, you might need the Maven Source Plugin and its source:aggregate goal (or maybe the Maven Assembly Plugin and the pre-defined src descriptor but source:aggregate is handy for multi-modules builds).
To bind the whole thing together (and maybe unpack sources), I'd use the Maven Assembly Plugin.
