As I understand it, the "SpringSource Bundlor Builder" is supposed to automatically be added to a project when the OSGi Bundle Nature is added. However, that seems to be a bit hit-and-miss. We've had several cases where that doesn't happen, which seems to affect the bundle dependencies container. We've manually edited the .project file to put it back in in those cases. However, is there a way to determine why it isn't there? And is there a way through eclipse to add it without having to manually edit the .project files?
