jenkins - 如何参数化 Jenkins 管道中复制工件的选择器

Question

我们在 Jenkins 系统中大量使用管道作业，并且需要能够参数化 copyArtifacts使用 Build selector for Copy Artifact 的步骤作业参数。

首先我发现 - 而参数返回 String - copyArtifacts步骤需要 BuildSelector 的实例.

我找到了 BuildSelectorParameter.getSelectorFromXml将参数转换为 BuildSelector 实例的方法喜欢:

properties([parameters([
    [$class: 'BuildSelectorParameter',
    defaultSelector: upstream(fallbackToLastSuccessful: true),
    description: '',
    name: 'copyArtifactSelector']])
])

@NonCPS
static BuildSelector getSelectorFromParam(String xmlText) {
    BuildSelectorParameter.getSelectorFromXml(xmlText)
}

node {
    def selector = getSelectorFromParam(params.copyArtifactSelector)
    copyArtifacts(
            projectName: 'sourceJob',
            selector: selector
    )
}

但是我刚刚意识到 BuildSelector创建的不是 Serializable .因此，我现在得到了预期的异常:

hudson.plugins.copyartifact.TriggeredBuildSelectorCaused: java.io.NotSerializableException: hudson.plugins.copyartifact.TriggeredBuildSelector    at org.jboss.marshalling.river.RiverMarshaller.doWriteObject(RiverMarshaller.java:860)    at org.jboss.marshalling.river.RiverMarshaller.doWriteFields(RiverMarshaller.java:1032)    at org.jboss.marshalling.river.RiverMarshaller.doWriteSerializableObject(RiverMarshaller.java:988)    at org.jboss.marshalling.river.RiverMarshaller.doWriteSerializableObject(RiverMarshaller.java:967)    at org.jboss.marshalling.river.RiverMarshaller.doWriteObject(RiverMarshaller.java:854)

After that I tried to check how the copy artifact plugin deals with that - unfurtunately I couldn't find any clue in the source code. Maybe it only works by chance? The methods to create a BuildSelector do not seem to create any kind of serializable class.

But maybe someone already came accross this issue and has a hint?

Edit

What I found so far:

• If I store the BuildSelector object in some variable it'll throw me the NotSerializableException.

• However if I do not pass it to some variable first but do the call in the method call to copyArtifacts the NotSerializableException will not occur - at least not for now:

  node {
      copyArtifacts(
              projectName: 'sourceJob',
              selector: getSelectorFromParam(params.copyArtifactSelector)
      )
  }
  


想法

Copy Artifact 插件中是否有可能导致 NotSerializableException 的隐藏错误？发生异常 - 或者我错过了什么？

题

使用我的 getSelectorFromParam 安全吗？方法像在更新的例子中完成的那样？如果不安全，是否有安全的解决方案？

在花了几个小时之后，我遇到了同样的问题，我发现了这一点，它对我来说非常有效。

的名称复制工件的构建选择器 这里的作业参数是 copyArtifactSelector，这里的上游作业名称是 sourceJob:

    copyArtifacts(projectName: 'sourceJob',
                  selector: [$class: 'ParameterizedBuildSelector', 
                             parameterName: 'copyArtifactSelector'] );

注意:插件=“copyartifact@1.39.1”

编辑:
与此同时 - 使用 copyartifact V1.43 - 支持以下语法:

    copyArtifacts(projectName: 'sourceJob',
                  selector: buildParameter('copyArtifactSelector'));
