如何在詹金斯中将变量从sh步骤导出到外部sh step

Question

我试图在构建后通过电子邮件发送文件的输出。内部版本更新文件file1.json。她是我的问题。构建后，我试图创建一个变量，该变量对应file1.json（正在运行），然后尝试通过emailext通过电子邮件发送该变量。

Stage {
       stage('Build'){\
         sh """
            npm install // builds and update the value in json file 
            UUID="`cat file1.json`"  //outputs the string inside file which is what I want 
            echo \$UUID //shows the value here
         """
         emailext body:  "$UUID", //need the value here 
           subject: "$currentBuild.currentResult-$JOB_NAME",
           to: 'someone@test.com'
} 
`
The error message is groovy.lang.MissingPropertyException: No such property: UUID for class: groovy.lang.Binding
    at groovy.lang.Binding.getVariable(Binding.java:63)
    at

您可以使用returnStdout: true步骤的选项sh()来获取shell的输出。

stage('Build'){

    script {

        sh 'npm install' // builds and update the value in json file 

        UUID = sh (script: 'cat file1.json', returnStdout: true).trim()

        emailext body:  "$UUID",  subject: "$currentBuild.currentResult-$JOB_NAME", to: 'someone@test.com'
    }

}
