jenkins - 如何在 jenkins 管道中连接两个 env 变量，中间有一个斜线？

Question

我有一个脚本可以将生成的 RPM 发送到 Nexus OSS 管理器。 Jenkins的阶段是:

stage ('nexus deploy') {
  env.REPONAME = "snapshots"
  sh '''
    mvn deploy:deploy-file -Durl="${env.NEXUS_URL}/$env.REPONAME"
    '''
  }

我已经设置了环境变量 env.NEXUS_URL但是用两个变量并排调用它，中间有一个斜线，不知何故没有检测到变量，并且构建失败并出现错误。

-Durl="${env.NEXUS_URL}/$REPONAME": bad substitution

Answer 1

你在混淆 groovy语法和 shell 中的语法.
您可以使用 env.VAR在 groovy你可以使用 ${VAR}之间sh '..' :

pipeline {
    agent any

    options {
        buildDiscarder(logRotator(numToKeepStr: '3'))
    }

    environment {
        NEXUS_URL = 'https://mynexus.com'
        REPONAME    = 'myrepo'
    }

    stages {
        stage('test') {
            steps {
                echo "print env vars in groovy"
                echo "my nexus is " + env.NEXUS_URL + " any my repo name is " + env.REPONAME
                sh 'echo "env vars in sh"'
                sh 'echo "nexus is ${NEXUS_URL} and my repo name is ${REPONAME}"'
            }
        }
    }
}

输出:

[Pipeline] echo
print env vars in groovy
[Pipeline] echo
my nexus is https://mynexus.com any my repo name is myrepo
[Pipeline] sh
[test] Running shell script
+ echo 'env vars in sh'
env vars in sh
[Pipeline] sh
[test] Running shell script
+ echo 'nexus is https://mynexus.com and my repo name is myrepo'
nexus is https://mynexus.com and my repo name is myrepo

在您的情况下，您需要:

mvn deploy:deploy-file -Durl=${NEXUS_URL}/${REPONAME}
