jenkins:: ERROR: Expected a step @ & pass generated values to downstream jobs

Question

我有一个 python 文件 peekaboo.py，它在独立 exec 上输出 json，如下所示。

python 文件输出（JSON）：

{"fernet_key": "some fernet_key", "db_url": "some_db_url", "pki_password": "some_pki_password"}

然而，当 jekins 试图运行同一个 python 文件时，它失败了，如下所示。

顺便说一下，这个 python 文件假设为 pki_client_cacert_password、db_url、fernet_key 设置值，这些值将被传递给 ansible playbook

pipeline {
    parameters {
    string(defaultValue: '', description: '', name: 'pki_client_cacert_password', trim: true)
    string(defaultValue: '', description: '', name: 'db_url', trim: true)
    }
    stages {
    stage('DeployToDev') {
            steps {
                env.artifacts = sh "/var/lib/jenkins/python_jobs/peekaboo_venv/bin/python3 /var/lib/jenkins/python_jobs/peekaboo.py --db_url=${env.db_url} --pki_password=${env.pki_client_cacert_password}"
                echo "${env.artifacts}" 
                ansiblePlaybook credentialsId: "${env.git_credential_id}", disableHostKeyChecking: true, extras: "-e \"pki_client_cacert_password=${env.pki_client_cacert_password} db_url=${env.db_url} fernet_key=${env.fernet_key} use_isrg_freetds=false\"",
            }
        }
    }
}

我们得到以下错误

错误：

WorkflowScript: 32: Expected a step @ line 32, column 21.
                       env.artifacts = sh "/var/lib/jenkins/python_jobs/peekaboo_venv/bin/python3 /var/lib/jenkins/python_jobs/peekaboo.py --db_url=${env.db_url} --pki_password=${env.pki_client_cacert_password}"

我的问题是，

如何修复此错误
如何访问生成的值以传递给 ansible 作业。

Answer 1

您可以尝试使用 sh 的赋值语句：

script{
   env.artifacts = sh(
     returnStdout: true, 
      script: "/var/lib/jenkins/python_jobs/peekaboo_venv/bin/python3 /var/lib/jenkins/python_jobs/peekaboo.py --db_url=${env.db_url} --pki_password=${env.pki_client_cacert_password}"
  )
}

这仅适用于管道作业，不适用于自由式作业。

Answer 2

我不得不添加脚本标签，并且还使用双引号 " 将字符串括起来

                script{
                    env.artifacts = sh(
                    returnStdout: true, 
                    script: "/var/lib/jenkins/python_jobs/peekaboo_venv/bin/python3 /var/lib/jenkins/python_jobs/peekaboo.py --db_url=${env.db_url} --pki_password=${env.pki_client_cacert_password}"
                    )
                }
