hudson.remoting.ProxyException: groovy.lang.MissingMethodException: 没有方法签名: java.util.LinkedHashMap.call() 是适用的

[英]hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method: java.util.LinkedHashMap.call() is applicable

当 body() 方法在我的管道 groovy 脚本中调用时,我收到“无签名”错误

我正在使用 Jenkins 共享库进行管道项目。 我已经在本地 Jenkins 中配置了共享库。 当我尝试访问我的共享库时,它被正确调用,但我无法解析共享库call()方法中的参数值。

我的共享库代码 ( myDeliveryPipeline.groovy )

def call(body) {
    println(body)

// evaluate the body block, and collect configuration into the object
    def pipelineParams= [:]
    body.resolveStrategy = Closure.DELEGATE_FIRST
    body.delegate = pipelineParams
    body()

    println (pipelineParams.BRANCH)
    println 'Map'
    println body
    println 'pipelineParams'
    println pipelineParams

    println 'Start pipeline steps'
   // our complete declarative pipeline can go in here

    pipeline {
        agent any

        // Stage checkout git
        stages {
            stage('checkout git') {
                steps{
                    git branch: 'master', url:'MY_GIT_HUB_URL'
                }
            }
        //checkout git ends

        // stage build
        stage('build') {
            steps{
                script{
                    if(isUnix()){
                            sh 'mvn clean package -Dmaven.test.skip=true'
                        }
                        else{
                            bat('mvn clean install -Dmaven.test.skip=true')
                        }
                    }
                }
            }
        // stage build ends

         // stage Test
         stage ('test') {
            steps{
                script{
                    if('yes' == 'yes'){
                        if(isUnix()){
                            parallel (
                                "unit tests": { sh 'mvn test' },
                                "integration tests": { sh 'mvn integration-test' }
                                )
                            }
                        else{
                            parallel (
                                "unit tests": { bat('mvn test')},
                                "integration tests": { bat('mvn integration-test')}
                                )
                            }
                        }
                    }
                }
            }
             // stage Test Ends
        }
        post {
            failure {
                mail to: 'MAIL_ID@gmail.com', subject: 'Pipeline failed', body: "${env.BUILD_URL}"
            }
            success{
                println "SUCCESS"
            }
        }
    }
}

在共享库文件vars/myDeliveryPipeline.groovycall的签名是call(<Closure>)

但是,我看到您正在调用它,因为它是call(<Map>)

因此,称之为:

myDeliveryPipeline {
  BRANCH=params.BRANCH
  RUN_TEST=params.RUN_TEST
  MAIL_TRIGGER=params.MAIL_TRIGGER
  EMAIL=params.EMAIL
}

而不是: myDeliveryPipeline(BRANCH:params.BRANCH, RUN_TEST:params.RUN_TEST, MAIL_TRIGGER:params.MAIL_TRIGGER, EMAIL:params.EMAIL)

到目前为止,签名已修复,但我可以看到您将闭包(主体)的 DELEGATION 从 Jenkins 覆盖到 Map。 因此, params是未定义的。

因此,我建议使用call(<Map>, <Closure>)重载call(<Closure>) call(<Map>, <Closure>)

def call(body) {
  call([:], body)
}

def call(pipelineParams, body) {
    body.resolveStrategy = Closure.DELEGATE_FIRST
    body.delegate = pipelineParams
    body()
    //...
}

现在,调用可以是:

myDeliveryPipeline(
 BRANCH:params.BRANCH,
 RUN_TEST:params.RUN_TEST,
 MAIL_TRIGGER:params.MAIL_TRIGGER,
 EMAIL:params.EMAIL
) {}

不要忘记最后一个{}

简要地 :

  • 如果要注入管道变量:(即参数,可以...),将它们注入在Map使用签名myDeliveryPipeline(Map,Closure)即使关闭是空的。

  • 如果你不依赖于管道的变量,你可以使用Closure使用签名myDeliveryPipeline(Closure)
