我有一个管道，我这样做：

#!/bin/groovy

pipeline {
    agent none
    environment {
        agent any
        INSTANCE_NAME = "Jenk"
  }

  stages {
    stage("Print Debug Vars"){
        steps {
            sh 'echo "INSTANCE_NAME is $INSTANCE_NAME"'
        }
    }

    stage("Git Checkout") {
        agent { label 'docker' }
        steps  {
            // ...
            }
      }
    }

    stage("Ansible Galaxy"){
        agent { label 'ansible' }
        steps  {
            // ...
            }
    }
  }
}

问题是如果我把

agent any

在环境部分，它说：

WorkflowScript: 6: "agent any" is not a valid environment expression. Use "key = value" pairs with valid Java/shell keys. @ line 6, column 5.
       agent any
       ^

WorkflowScript: 5: Expected name=value pairs @ line 5, column 5.
       environment {
       ^

如果我不放，我会得到：

Required context class hudson.Launcher is missing
Perhaps you forgot to surround the code with a step that provides this, such as: node
[Pipeline] // withCredentials
[Pipeline] }
[Pipeline] // withEnv
[Pipeline] End of Pipeline

environment可以全局设置（针对整个流水线）和每级设置（check official documentation）。但是如果agent none应用于整个管道，它就不能全局设置-这是有意义的，因为如果没有代理，那么环境变量就不能应用于它。
如果你真的需要在流水线级别使用agent none，那么将你的环境块添加到你需要它的阶段：

#!/bin/groovy

pipeline {
  agent none
  stages {
    stage("Print Debug Vars"){
      agent any
      environment {
        INSTANCE_NAME = "Jenk"
      }
      steps {
        sh 'echo "INSTANCE_NAME is $INSTANCE_NAME"'
      }
  }
  ...
}

此外，agent any应直接应用于stage-在environment块中使用它是无效的
当然，首先要考虑使用agent none--它应该使用例如。这样在等待用户输入时没有代理被阻塞。如果你的管道不能做到这一点，也许你可以在顶层使用agent any。

你有没有试过只使用任何值的agent，像这样：

#!/bin/groovy

pipeline {

  agent any

  stages {
    stage("Print Debug Vars"){
        steps {
            sh 'echo "INSTANCE_NAME is $INSTANCE_NAME"'
        }
    }

    stage("Git Checkout") {
        agent { label 'docker' }
        steps  {
            // ...
            }
      }
    }

    stage("Ansible Galaxy"){
        agent { label 'ansible' }
        steps  {
            // ...
            }
    }
  }
}
