## Jenkinsfile: git rev-parse --abbrev-ref HEAD returns HEAD ##

通过 git rev-parse --abbrev-ref HEAD 获取分支名时，返回为 HEAD，

通过安装 Jenkins 插件， 直接获取通过 **$\{BRANCH\_NAME\}** 获取

## Jenkins pipeline中获取 项目版本号 ##

直接运行 `mvn help:evaluate -Dexpression=project.version -q -DforceStdout` 报错

获取 Project Version

TMP_VERSION = sh (
          script: 'mvn help:evaluate -Dexpression=project.version -q -DforceStdout',
          returnStdout: true
    ).trim()
