詹金斯管道异常java.io.NotSerializableException:hudson.model.FreeStyleProject [英] Jenkins pipeline exception java.io.NotSerializableException: hudson.model.FreeStyleProject

问题描述

我创建了Job管道，并尝试在并行启动后获取所有与regexp匹配的作业.我得到异常:java.io.NotSerializableException:hudson.model.FreeStyleProject 詹金斯v 2.5

I create Job pipeline, and I try get all jobs which matches regexp, and after parallel start. I get exception: java.io.NotSerializableException: hudson.model.FreeStyleProject Jenkins v 2.5

node {
    stage('deploy') {
        def branches = [:]
        def theJobs = Jenkins.instance.getAllItems(Job);
        for(int i = 0; i < theJobs.size; i++)
        {
            def jobName= theJobs[i].getName();             
            if( jobName =~ /server\-[0-9][0-9]\..*/)
            {
                branches[i] = {
                    build job : "${jobName}", parameters: [[$class: 'StringParameterValue', name: 'BRANCH', value: "${BRANCH}"] ]
                }
            }
            jobName = null
        }
        parallel branches
    }
}

完成:失败

推荐答案

Jenkins流水线的功能如此强大，可以在各种故障情况下继续运行，例如主服务器或代理发生故障.为此，存储了管道的每个中间步骤，因此管道知道发生故障时应从何处恢复.

A Jenkins Pipeline has been made so robust that it can resume in various failure scenarios, like a master or agent going down. To be able to do this, every intermediate step of the Pipeline is stored, so the Pipeline know where to resume in case of a failure.

要存储管道步骤，它们必须为Serializable.您的情况def theJobs = Jenkins.instance.getAllItems(Job);不可序列化，因为列表中的条目是FreeStyleProject而不是implements Serializable.

To store the Pipeline steps, they must be Serializable. In your case def theJobs = Jenkins.instance.getAllItems(Job); is not serializable since an entry in the list is a FreeStyleProject and that does not implements Serializable.

一种解决此问题的方法是将所有使用不可序列化步骤的代码移到一个方法中，并使用@NonCPS对该方法进行注释.这会通知管道不要尝试存储此方法的结果，因此不需要序列化它.如果发生故障并且需要在尚未执行的步骤中使用此方法的结果，则将再次执行此方法.

A way to workaround this is to move all code that uses non-serializable steps into a method and annotate that method with @NonCPS. That signals to the Pipeline to not try and store the result of this method, so it needs not serialize it. Should a failure occur and and the result from this method be needed in a yet to execute step, then this method will be executed again.

在您的示例中:

node {
    stage('deploy') {
        parallel getBranches()
    }
}

@NonCPS
def getBranches() {
    def branches = [:]
    def theJobs = Jenkins.instance.getAllItems(Job);
    for(int i = 0; i < theJobs.size; i++)
    {
        def jobName= theJobs[i].getName();             
        if( jobName =~ /server\-[0-9][0-9]\..*/)
        {
            branches[i] = {
                build job : "${jobName}", parameters: [[$class: 'StringParameterValue', name: 'BRANCH', value: "${BRANCH}"] ]
            }
        }
        jobName = null
    }
    return branches
}
