当 sh 输出包含左括号（| Jenkins 声明性管道

Question

我正在尝试在其中一个步骤中将一些数据写入文件，然后在之后的步骤中使用读取该数据并将其分配给一个变量。这是我的声明式 Jenkins 管道：


pipeline {
    agent {label 'build-slave-aws'} 
    stages {
        stage('Notify about start') {
            steps {
                sh 'echo "Some fatct with brackets ()" > /tmp/facts.issues'           
            }
        }

         stage('Gather the facts') { 
            steps {
                    script {
                        factsIssues = sh( script: "cat /tmp/facts.issues", returnStdout: true )
                    }

                   sh "echo these are facts: ${factsIssues}"     
            }
        }
    }
}

此运行的输出如下：

任何其他不包含 ( 的文本都可以正常工作。关于如何使用 ( 在文件中写入一些数据并将其读回变量，您有什么建议吗？

Answer 1

您在最后一个 sh 脚本中遗漏了 echo 命令参数的引号。

修复：

sh "echo 'these are facts: ${factsIssues}'"
