I try to migrate to Jenkins 2.0 and Jenkinsfile pipeline definition.
Base idea:

• on any commit build make all artifacts;
• on tag build also publish this artifacts to "GitHub releases" and etc.

Ideally I want something like from Travis world:

install:
- ./build.package.sh
deploy:
  - provider: script
    script: ./publish.manual.sh
    on:
      branch: master
  - provider: script
    script: ./publish.release.sh
    on:
      tags: true

My project located on GitHub and I simply created "Multibranch Pipeline" with "GitHub"
Branch Source. This solved common commit build pipeline. But it can't build git tags.

I have no idea, how make build for automatic tag build. But manual build trigger is not a problem for me.

I try to create a "Pipeline" with string parameter "TAG_NAME" and "Pipeline script from SCM" with "Branch Specifier" = "refs/tags/${TAG_NAME}". But this don't work (looks like TAG_NAME is not pass to environment variable).

Aslo I can't use "TAG_NAME" parameter value on build with default "Branch Specifier" = "*/master".
