从 Jenkins 管道并行步骤收集数据 [英] collect data from Jenkins pipeline parallel steps

问题描述

从并行步骤收集数据(例如通过/失败结果)的最佳方式是什么.

What would be the best way to collect data (such as pass/fail results) from parallel steps.

到目前为止我已经达到了什么:

What I've reached so far:

#!groovy
def fspam(name, spam){
    spam[name] = "BEEN THERE TOO"
}

// pipeline
node('slave'){
    stage("test"){
        targets = ["a", "b"]
        def tasks = [:] 
        def spam = [:]
        targets.each{ tasks["${it}"] = {
            node('slave'){
                echo "dry-run ${it}"
                spam[it] = "BEEN THERE" <--- works
                fspam(it)         <--- fails
            } 
        } 

        }
        parallel tasks
        print("spam")
        print(spam)
    }
}

但它失败了:

另外:groovy.lang.MissingPropertyException:没有这样的属性:stam对于类:WorkflowScript groovy.lang.MissingPropertyException:否这样的属性:stam 类:WorkflowScript atorg.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:53)

Also: groovy.lang.MissingPropertyException: No such property: stam for class: WorkflowScript groovy.lang.MissingPropertyException: No such property: stam for class: WorkflowScript at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:53)

1. 似乎封闭式可以成功填充地图，但是在使用函数时会引发错误
2. 我不确定拥有一张全球地图是最好/最干净的方式

任何建议

推荐答案

使用.asSynchronized():

targets = ["a", "b"]

tasks = [:]
spam = [:].asSynchronized()

targets.each { target ->
    tasks[target] = {
        echo "dry-run ${target}"
        spam[target] = "BEEN THERE"
        fspam(target, spam)         // <--- passing spam fixes the issue
    } 
}

parallel tasks

print("spam")
print(spam)

这保证了对地图的更新是线程安全的.要收集列表，您可以使用 [].asSynchronized().链接

This guarantees that updates to the map are thread-safe. For collecting a list, you can use [].asSynchronized(). Link
