I want to get Heroku-like functionality for deploying new version - just git push and you're done. Crazy sexy cool.
I did try with git hooks in various ways, but since I run the server as a nohup jetty-process (I know) and have to kill that in brutal ways, cannot be sure on the merging of the branches since I had the git repo checked out (use a intermediate bare repo, please) I could not get it work. It was also really hard to know what was happening.
The search light is now against lein-war (for running in tomcat7) and some nice pallet solution.\
Git hooks is awesome for other things, but they are no system deployment/ continuous integration tool.
Update: I'm now a happy Jenkins user. Easy to get started with!
