Jenkins Pipelines:如何从共享变量脚本中使用withCredentials() [英] Jenkins Pipelines: How to use withCredentials() from a shared-variable script

问题描述

我想在共享变量("vars/")脚本中使用withCredentials()块，而不是直接在Jenkins管道中使用，因为这是特定库的低级语义，并且可能视情况而定，可能不需要.但是，withCredentials(或至少它的签名)似乎不在范围内.

I'd like to use a withCredentials() block in a shared-variable ("vars/") script rather than directly in the Jenkins pipeline because this is a lower-level semantic of a particular library, and also may or may not be required depending on the situation. However, withCredentials (or, at least, that signature of it) doesn't appear to be in scope.

脚本:

def credentials = [
    [$class: 'UsernamePasswordMultiBinding', credentialsId: '6a55c310-aaf9-4822-bf41-5500cd82af4e', passwordVariable: 'GERRIT_PASSWORD', usernameVariable: 'GERRIT_USERNAME'],
    [$class: 'StringBinding', credentialsId: 'SVC_SWREGISTRY_PASSWORD', variable: 'SVC_SWREGISTRY_PASSWORD']
]

withCredentials(credentials) {
// ...
}

控制台:

hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method: BuildagentInstallAndRun.withCredentials() is applicable for argument types: (java.util.ArrayList, org.jenkinsci.plugins.workflow.cps.CpsClosure2) values: [[[$class:UsernamePasswordMultiBinding, credentialsId:6a55c310-aaf9-4822-bf41-5500cd82af4e, ...], ...], ...]

有人能成功吗?

推荐答案

我使用的是共享库，而不是共享变量，但我想这是类似的情况. 我没有使用$class参数，而是直接调用了管道摘要生成器建议的功能之一.您可以在此处获得列表.在下面的示例中，我使用usernameColonPassword绑定. 在管道中，我实例化了类实用程序，并将this传递给了构造函数.然后，在库中，我使用step对象访问管道步骤(例如withCredentials或usernameColonPassword).

I'm using a shared library rather than a shared variable, but I guess it is a similar situation. I'm not using the $class parameter, but i'm calling directly one of the functions suggested by the pipeline snippet generator. You can have a list here. In the example below, I use the usernameColonPassword binding. In the pipeline, I instantiate the class utilities and I pass this to the constructor. Then, in the library, I use the step object to access the pipeline steps (such as withCredentials or usernameColonPassword).

class Utilities implements Serializable {
    def steps
    Utilities(steps) {
        this.steps = steps
    }
    def doArchiveToNexus(String credentials, String artifact, String artifact_registry_path){
        try {
            this.steps.withCredentials([steps.usernameColonPassword(credentialsId: credentials, variable: 'JENKINS_USER')]) {
                this.steps.sh "curl --user " + '${JENKINS_USER}' + " --upload-file ${artifact} ${artifact_registry_path}"
            }
        } catch (error){
            this.steps.echo error.getMessage()
            throw error
        }
    }
}
