jenkins - 从 Jenkins 管道并行步骤收集数据

Question

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。

到目前为止我所达到的目标:

#!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)
    }
}

但是失败了:

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. 看起来闭包中它成功填充了 map ，但是在使用函数时它会抛出错误
2. 我不确定拥有全局 map 是最好/最干净的方式

任何建议

Answer 1

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 map 的更新是线程安全的。要收集列表，您可以使用[].asSynchronized()。 Link
