Question

我正在尝试创建一个在具有特定标签的所有在线节点上运行的简单作业。我可以获取节点名称，并期望下面的代码可以工作。但是我得到以下例外。

def newJob(x)
{
    return  {
        node(x) {
            bat "dir"
        }
    }
}

def jobs = [:]

def lgroups = Jenkins.instance.getLabel('win7')
for (g in lgroups) {
    for (node in g.getNodes()) {
        def nodeName = node.getNodeName()
        if (Jenkins.instance.getNode(nodeName).toComputer().isOnline())
        {
            jobs["${nodeName}_BS"] = newJob(nodeName)
        }
    }
}

parallel jobs

作业配置为在未启用沙箱的情况下运行。例外：

您必须将不可序列化的代码提取到使用@NonCPS注释的方法中，可能类似于以下内容：

@NonCPS
def getParallel() {
    def jobs = [:]
    def lgroups = Jenkins.instance.getLabel('win7')
    for (g in lgroups) {
        for (node in g.getNodes()) {
            def nodeName = node.getNodeName()
            if (Jenkins.instance.getNode(nodeName).toComputer().isOnline())
            {
                jobs["${nodeName}_BS"] = newJob(nodeName)
            }
       }
    }
    return jobs
}

parallel getParallel()
