How to push changes to github after jenkins build completes?
The git checkout master of the answer by Woland isn't needed. Instead use the "Checkout to specific local branch" in the "Additional Behaviors" section to set the "Branch name" to master.
The git commit -am "blah" is still needed.
Now you can use the "Git Publisher" under "Post-build Actions" to push the changes. Be sure to specify the "Branches" to push ("Branch to push" = master, "Target remote name" = origin).
"Merge Results" isn't needed.
Found an answer myself, this blog helped: http://thingsyoudidntknowaboutjenkins.tumblr.com/post/23596855946/git-plugin-part-3
Basically need to execute:
git checkout masterbefore modifying any files
then
git commit -am "Updated version number"after modified files
and then use post build action of Git Publisher with an option of Merge Results which will push changes to github on successful build.
Actually, the "Checkout to specific local branch" from Claus's answer isn't needed as well.
You can just do changes, execute git commit -am "message" and then use "Git Publisher" with "Branch to push" = /refs/heads/master (or develop or whatever branch you need to push to), "Target remote name" = origin.
