如何让Jenkins从Jenkinsfile中的命令生成的控制台输出中提取值？
具体来说，我如何让Jenkins从下面这个非常简单的Jenkinsfile中的checkout scm命令的结果中提取提交哈希？

Jenkinsfile

node {
    // Clean workspace before doing anything
    deleteDir()
    try {
        stage ('Clone') {
            checkout scm    
        }
    } catch (err) {
        currentBuild.result = 'FAILED'
        throw err
    }
}

字符串

checkout scm命令输出：

Jenkins日志在上面简化的Jenkinsfile中运行checkout scm命令后打印以下内容：

重复提问：

具体来说，我们要向Jenkinsfile添加什么，以便日志在结尾处额外打印出以下内容：

Commit hash is:  77cf12f42136efc77fecbcd1f761a54254278cb3

这显然过于简化了。在真实的生活中，打印输出将进入变量，并作为参数传递到脚本中。但是对于这个问题，什么特定的语法将使Jenkins能够提取提交哈希？

如果你特别需要commit hash，checkout步骤的文档提到了一个简单的方法来获得它（而不是解析控制台输出等）：
这一步返回SCM插件在Freestyle作业中设置的任何变量的Map，所以如果你的SCM是git，你可以这样做：

def scmVars = checkout scm
    def commitHash = scmVars.GIT_COMMIT

    // or

    def commitHash = checkout(scm).GIT_COMMIT

字符串
一旦你把它放在一个变量中，你只需要回显它就可以在日志中看到它。

echo "Commit hash is: ${commitHash}"
