Me neither. I get the feeling they just made one up as they modularized the JDK. I've built the JDK quite a few times, but I never actually looked into what they're using to build the Java sources. It appears that it's just Makefiles, so they presumably didn't have the conventions of any existing tool to work with. > What I've seen in OSGi is to name the directories according to the > modules (bundle names) but this often leads into duplication > like: Yep, I actually adopted this convention myself at the start of the year. I think the one advantage to this over the short form is that it can make it slightly easier to find modules in the filesystem if you have a lot of source trees: $ find . -name 'com.io7m.example' -type d > I think the best suggestion I can give is to keep the conventions > ...cause from my current point of view you don't have disadvantages... > > But we would be very interested if there are some if you make > experiences in that way...

Well, in a few weeks time, I'll have at least attempted to modularize some 60 different projects. They're all OSGi compatible, so the difficult work has already been done. Just need to write module descriptors and update plugins and definitions to produce 9 bytecode. I can certainly write something up.
