jenkins - 如何在 Jenkins 声明性管道中设置 PATH

Question

在 Jenkins 脚本化管道中，您可以像这样设置 PATH 环境变量:

node {
   git url: 'https://github.com/jglick/simple-maven-project-with-tests.git'
   withEnv(["PATH+MAVEN=${tool 'M3'}/bin"]) {
      sh 'mvn -B verify'
   }
}

请注意 PATH+MAVEN，如此处所述 https://jenkins.io/doc/pipeline/steps/workflow-basic-steps/#code-withenv-code-set-environment-variables :

A list of environment variables to set, each in the form VARIABLE=value or VARIABLE= to unset variables otherwise defined. You may also use the syntax PATH+WHATEVER=/something to prepend /something to $PATH.

但我没有找到如何使用环境语法在声明式管道中执行此操作(如此处解释: https://jenkins.io/doc/pipeline/tour/environment )。

environment {
    DISABLE_AUTH = 'true'
    DB_ENGINE    = 'sqlite'
}

理想情况下，我想更新 PATH 以在所有阶段使用自定义工具。

可以使用环境部分:

pipeline {
  agent { label 'docker' }
  environment {
    PATH = "/hot/new/bin:${env.PATH}"
  }
  stages {
    stage ('build') {
      steps {
        echo "PATH is: ${env.PATH}"
      }
    }
  }
}
