Jenkins 带有自定义步骤和库的管道Groovy错误

我的Jenkins 2.0管道库和自定义步骤有以下问题

来自repo X的My Jenkins文件包含：

@Library('acme-pipelines@dev')

import acme.jenkins.*

node {
    runGradle {
        version = '3.3'
        cmd = '--version'
    }
}

在repo Y管道库repo i中，vars/runGradle.groovy包含：

import acme.jenkins.*

def call(body) {
    def config = [:]
    def utils = new Utils()

    body.resolveStrategy = Closure.DELEGATE_FIRST
    body.delegate = config
    body()

    sh "${utils.getGradleBinPath(config.version)} ${config.cmd}"
}

package acme.jenkins

static String getGradleBinPath(String version = null) {
    if (!version) {
        throw new IllegalArgumentException('No Gradle version supplied')
    }
    tool(version).concat('/bin/gradle')
}

同样在repo Y中，我有src/acme/jenkins/Utils.groovy，其中包含：

import acme.jenkins.*

def call(body) {
    def config = [:]
    def utils = new Utils()

    body.resolveStrategy = Closure.DELEGATE_FIRST
    body.delegate = config
    body()

    sh "${utils.getGradleBinPath(config.version)} ${config.cmd}"
}

package acme.jenkins

static String getGradleBinPath(String version = null) {
    if (!version) {
        throw new IllegalArgumentException('No Gradle version supplied')
    }
    tool(version).concat('/bin/gradle')
}

当我运行管道时，出现以下错误：

如果我将getGradleBinPath方法包装在名为Utils的类中，无论是否使用该方法的静态关键字前缀，这都是相同的错误，我在使用该类版本时也尝试实现Serializable，但我得到了相同的错误

如果我删除脚本版本中的static关键字，它就可以正常工作，所有示例代码场景和上面提到的都会产生相同的错误

我是Groovy的新手，所以如果这与Jenkins无关，或者非常琐碎，请原谅。

您不能直接在src目录下的classes\scripts中访问管道标准步骤。您应该将这些步骤传递给构造函数/设置器或作为方法参数。 这样的办法应该行得通 src/acme/jenkins/Utils.groovy

然后在vars/runGradle.groovy中

看

请注意，步骤是一个标准的全局变量，用于保存管道步骤。

不知何故，我在文档中忽略了这一点。您的实现工作正常，但需要进行一次小的编辑，我还需要实现可序列化接口，否则我会在acme.jenkins.Utils上得到一个java.io.NotSerializableException异常，请您编辑您的答案，以便我将其标记为例外？作为旁注，如果有人能够介入并解释为什么不实现Serializable接口它就无法工作，这将是非常有帮助的。值得一提的是，如果您不需要暂停和恢复使用runGradle自定义步骤的Jenkins管道，您可以将@NonCPS decorator添加到vars/runGradle.groovy中的调用方法中，在这种情况下，您不需要在Utils类上实现可序列化接口。@Nicolae这是因为Jenkins管道使用CPS转换。你可以多读一些。我想应该是新的。这是吗？
