How to set up the Harmony working environment. (get the git-new-workdir script from git distribution in git-1.5.*/contrib/workdir/git-new-workdir and install somewhere on your PATH).

  git clone git://repo.or.cz/harmony.git trunk
  cd trunk
  git checkout -b trunk origin/trunk
  git branch common_resources origin/common_resources
  git new-workdir . common_resources common_resources
  git branch drlvm origin/drlvm
  git new-workdir . working_vm drlvm
  git branch classlib origin/classlib
  git new-workdir . working_classlib classlib
  git branch jdktools origin/jdktools
  git new-workdir . working_jdktools jdktools
  git branch concurrent origin/concurrent
  git new-workdir . working_classlib/modules/concurrent/standard concurrent

If you do not want to use git-new-workdir script, use regular git-clone command:

  git clone git://repo.or.cz/harmony.git trunk
  cd trunk
  git clone . working_classlib
  cd working_classlib
  git fetch .. refs/remotes/origin/classlib:refs/remotes/origin/classlib
  git checkout -b classlib origin/classlib
  cp ../.git/config .git/ # to fix 'origin' repo (by default it would be '..')

When it is time to update the workspace, you have to do it individually for each module, like

  cd working_classlib
  git pull

Also please consider editing your .git/info/exclude file to avoid git status complaining about untracked directories

  cat >> .git/info/exclude <<eof
  /working_*
  /common_resources
  eof

etc.
