Mirroring Git/GitHub to Hg/BitBucket

This seemed a lot longer when I planned it in my notebook at lunch.

1. Install hg-git
   • You’ll have to do this on the Jenkins server
   • You’ll have to do it either for the Jenkins user or all
   • I’m using an OsX machine as my host, so I was able to use easy_install to install hg-git and dulwich
2. setup a project on GitHub
3. create a Jenkins Freestyle project which runs periodically
   • Polling the SCM was NOT an option since there’s no default branch on GitHub
     • … this is a quirk of hg-git … I think
     • … IIRC/YRMV - so sling me a tweet or whatever if I’m wrong

4. program the job to pull from git, push to hg, and ignore results of 1

   • this was only elaborate because I needed it to not fail when there were no changes

     #!/bin/bash
     
     if [ -d "imgui" ]; then
         echo "Re-Using ImGUI"
         cd imgui
         hg pull git+ssh://git@github.com:ocornut/imgui.git
     else
         echo "Cloning ImGUI"
         hg clone git+ssh://git@github.com:ocornut/imgui.git
         cd imgui
     fi
     
     hg push -f ssh://hg@bitbucket.org/g-pechorin/imgui
     
     retcode=$?
     
     if [ $retcode -eq 0 ] || [ $retcode -eq 1 ]; then
         exit 0
     else
         exit $retcode
     fi
