我面对

getThingsDone() 适用于参数类型：() 值：[]

代码错误如下，

in shared library ....
vars/pipeline.groovy

def getThingsDone(m = null){
   echo "done"
}

in some project that includes shared library

@Library(shared_pipeline@branch_name) _
pipeline.getThingsDone()

我尝试定义 getThingsDone(...)

  • 没有任何论据
  • 带字符串参数
  • 使用地图参数

没有任何效果。所以我想要一个不接受任何参数的函数启动并运行。但它分解了整个堆栈跟踪，如下所示，

全局变量需要从脚本指令访问

在上述情况下，getThingsDone() 是一个全局函数。并且根据https://issues.jenkins-ci.org/browse/JENKINS-42360，不允许在脚本指令之外使用全局变量/函数。

问题：您配置了一个外部 Jenkins 共享库，其中包含一些您想在 jenkins 管道中使用的功能。但是，您的 Jenkins 无法识别方法签名并引发异常。

问题：

hudson.remoting.ProxyException: groovy.lang.MissingMethodException: 
No signature of method: java.lang.Class.someMethodName()

解决方案：

to 之间的关系如下：

<shared library> contains: <some function> -> jenkins imports this function and can use it.

  1. 验证函数名称没有Typo 或 Missing Characters，验证输入参数的顺序是否正确。

  2. 您需要验证库是否正确导入。

    @Library('my-shared-library') _

/* Using a version specifier, such as branch, tag, etc */
@Library('my-shared-library@1.0') _

/*Accessing multiple libraries with one statement */
@Library(['my-shared-library', 'otherlib@abc1234']) _

  3. 全局函数应包含在脚本指令中，例如文件名：startServer.groovy

    #!/usr/bin/env groovy

def call() {
    script{
        sh """#!/bin/bash -le
            cd ${workspace}/app
            npm start
        """
    }
}

[关于詹金斯管道：]

 //pipeline code...
  startServer()

  1. 如果您在 groovy类中声明静态函数，请确保该类以小写字母开头。例如使用：nodeUtils.groovy而不是Nodeutils.groovy（由于某种原因无法识别）

     #!/usr/bin/env groovy

    def startServer() {
        script{
            sh """#!/bin/bash -le
                cd ${workspace}/app
                npm start
            """
        }
    }

    def installPackages() {
        script{
            sh """#!/bin/bash -le
                cd ${workspace}/app
                npm install --save-dev
            """
        }
    }

[关于詹金斯管道：]

//pipeline code...
nodeUtils.installPackages()
