    Cool!

    I like the diagram, it makes the big-picture easier to grasp.

    Here are my list of thoughts on this and I'm totally open to any
    feedback on it.

    So to invert the list Andrus put together and put it in terms of
    dependencies (transients implied and not explicitly listed)

    Module Dependencies
    cayenne-core - external stuff
    cayenne-core-java-1.5 cayenne-core
    cayenne-remote cayenne-core
    cayenne-server cayenne-core, cayenne-remote
    cayenne-server-java-1.5 cayenne-server
    cayenne-jpa cayenne-server (shouldn't this be cayenne-core-java-1.5?)
    cayenne-webobjects cayenne-core
    modeler-plugin swing-plugin, cayenne-webobjects, cayenne-server
    swing-plugin plugin-launcher
    plugin-launcher - external stuff

    We have 3 Assemblies:

    Generic Java Runs Anywhere (modeler without platform specific launcher)
    OSX Cayenne Modeler Launcher
    Windows Cayenne Modeler Launcher

    This I think is the big picture and will be a guide to our assemblies
    and internal dependencies.

    On the site, I'm positive that we can use the existing layout and
    images, I'm just not sure how to make that happen. I will look into
    that and post another thread on it.

    There are also a bunch of changes that need to happen to the layout
    of the directories of the code. Once we have agreement that this is
    the proper dependency and assembly stuff I'll get started on putting
    the pom's together.

    I will post another thread about directory layout changes.

    In the mean time here are some url's to m2 documentation for those
    interested;

    http://maven.apache.org/guides/getting-started/index.html

    http://maven.apache.org/guides/introduction/introduction-to-the-
    standard-directory-layout.html

    You can also get a free copy of 'Better Builds With Maven' from here;

    http://www.mergere.com/m2book_download.jsp

    You can get it here;

    http://tinyurl.com/paany

    with my registration but I'm not sure how long that will last before
    they force you to 'login' again. I get about 1 or 2 emails from them
    a months for he joy of the book, I think there is an 'opt out' but
    its not that annoying so I just delete them.

    I reviewed the book while I was learning m2 and found it quite helpful.

    I'm off to do directory structure spelunking.

    TTFN,
