What remains now is the the github webhook is configured ONLY for pushes. Unfortunately.. it seems that jenkins isnt able to handle any other kinds of hooks yet. The jenkins itself is set to only build the master branch.

So this means that we will build on master when there is any push on github, or on the branch things are pushed on?

It would mean that jenkins would be built only when a push was made to master.
Other branches would be sent in the webhook, but jenkins will ignore them..

Well that's good enough I suppose. It means that jenkins build anything that gets upgraded to master, which is stable releases. I'm updating the hook.

Done.
