Jenkins 管道插件如何运行并行任务

我是 jenkins 的初学者，我想使用管道插件在 jenkins 的可用从节点上并行启动一些任务。

我安装了管道插件并在管道内联脚本部分添加了下面的内容。

grovvy script : 
    parallel firstBranch: {
        node('master'){
            echo 'firstBranch'
        }
    }, 
    secondBranch: {
        node('slave1'){
            echo 'secondBranch'
        }
    }

注意 : master 和 slave1 是我的节点

理想情况下 firstBranch 和 secondBranch 是什么？？？？

控制台输出:

Started by user anonymous [Pipeline] parallel [Pipeline] [firstBranch] { (Branch: firstBranch) [Pipeline] [secondBranch] { (Branch: secondBranch) [Pipeline] [firstBranch] node [firstBranch] Running on master in /scratch/gnithyan/.hudson/workspace/pipeline_test
[Pipeline] [secondBranch] node
[Pipeline] [secondBranch] // node
[Pipeline] [secondBranch] }
[secondBranch] Failed in branch secondBranch
[Pipeline] [firstBranch] {
[Pipeline] [firstBranch] echo
[firstBranch] firstBranch
[Pipeline] [firstBranch] }
[Pipeline] [firstBranch] // node
[Pipeline] [firstBranch] }
[Pipeline] // parallel
[Pipeline] End of Pipeline

我也有同样的问题。也许我找到了依赖插件:

请参阅版本 2.10 的发行说明
在 2.9 中并行处理某些步骤的日志处理回归。

是的，更新插件有效!
