I also have similar situation. Each build is creating tag which is created during build (in buildscript) and it pretty hard to push it back to repository. Credentials are removed just after clone and it is not so simple to add them back during build. I've ended with setting remote URL to contain credentials (my repo is using http authentication) to be able to push. However having feature like 'Push all tags to remote' would be very nice

"Post-build Actions" -> "Git publisher"

I don't think it is possible to use Git publisher to publish tags created during build (not using Git publisher).

As Maciej already answered - it is currently not possible to push back arbitrary tags created during the build - you can only create a tags with a fixed name.

I already created a pull request which mate it into git-client-plugin 1.11.1. I also have the changes for git-plugin but didn't have the time to create tests. Maybe I'll have time tomorrow.

"Each build is creating tag which is created during build " - "Additional behavior" -> "tag every build" ?

I do not want to use Git publisher to create tag. I want it only to push tag that I create during build, eg. in Makefile using git tag "build/$my_awesome_variable"

"Git publisher" doesn't create tags, it only publishes.
1) Extend "git publisher" so it will be able to push external tags.
2) Extend "create build tag for every build" with ability to set custom name.
