使用Maven / Jenkins / Git创建发布标签

Question

I'm using Jenkins,GIT and Maven as part of my development process. I have two branches develop and master. As usual i do my development on develop, test it and merge it to master for the jar to be published.

I'm using Jenkins to deploy my snapshots/release jars to our Nexus repository. When i deploy/publish the release jar (one without -SNAPSHOT) i would like to create a release TAG in my github repo, while i want to avoid that while deploying my snapshots.

I went through the posts at http://www.dev9.com/article/2014/9/java-release-process-with-continuous-delivery and https://axelfontaine.com/blog/final-nail.html to get some idea.

My questions are the following:

• Do i need to keep two different Jenkins job for my develop and master branches? The one for master will have the configuration with maven-scm-plugin and maven-version-plugin to create the tag.
• Do I need to remove the '-SNAPSHOT' from the version in pom.xml of my master branch? I know the scm plugin will remove those while creating the tag, but i suppose maven will publish/deploy the jar with '-SNAPSHOT'? While running the Jenkins job for my master branch, i would like to deploy 1.0.0.jar and not 1.0.0-SNAPSHOT.

Basically you need the following plugin : http://maven.apache.org/maven-release/maven-release-plugin/

The plugin do the following :

• 1) remove the -SNAPSHOT, and commit
• 2) Tag the version in git, commit
• 3) Increment the version number and add -SNAPSHOT, commit
• 4) Push those change

What it look like in jenkins (configuration of the job)
