What should be committed to the repository in the Eclipse workspace?

I have a Ecli开发者_开发知识库pse installed to work with BIRT reports. What files in the workspace should be committed to the repository and what files should not?

---

Basically, any file able to help a developer checkout the repo and (almost) immediately open the project to work on it.
That should include at least eclipse files like .project, .classpath, and some IDE settings.
They might be some BIRT-specific settings as well.
