Useful resources
I thought I would start a thread to share useful resources that people know about or have come across that others could also benefit from.
These newsgroups for Eclipse have a lot of information in them and are useful for asking questions or doing directed searches for Eclipse specific information.
http://www.eclipse.org/newsportal/index.php
Specifically the eclipse.technology.equinox and eclipse.platform.pde newsgroups may be most relevant for us. Also if you are new to Eclipse the eclipse.newcomer group is a great place to ask questions. It is probably worth mentioning that the eclipse.technology.kepler group is not directly related to our project but was a proposal for an eclipse project that seems to have not moved past the proposal stage.
An important part of the framework for Kepler is going to be dependency management so here are a couple links for tools that help with that. If you know of others I'd certainly be happy to hear about them.
JDepend - I have some Java programs that use this if you'd like more examples
I have just found out about JSR 277. This is a good article that discusses it from an OSGi point of view.
