I've spent the whole day looking at tycho and am going to have to put it to one side for the time being.
I'm not clear what, if any, relevance tycho-bundles-external-0.25.0.zip has to the build? My guess is that in order to build eclipse, various OSGi bundles like org.eclipse.osgi.services need to be pulled in from a P2 repository, but it's beyond my current level of understanding to see how to do this. (I'm not a Java programmer - and I've no prior knowledge of OSGi). Perhaps someone more experienced in this area might be able to take a look?
