Eclipse: Storing info in .project file

I'm trying to associate information with projects (certain properties). I tried using the persistence store (getPersistentProperty() and setPersistentProperty()).

The problem with that is that when I export the project and re-import it in a different workspace, those properties are gone (since they are stored somewher开发者_开发知识库e in the .metadata folder of the workspace).

So I was thinking that if there's a way to store the info in the .project file then this would solve my problem because this file is always included when projects are exported.

Is there an API to do that?

Any pointers would be appreciated! Thank you!

Regards, T

You may need to consider using a configuration scope to store preferences across workspace.
See project scope preferences.
Using Store (as discussed in this thread), you also get some details on the nature of a configuration in this FAQ.
