访问先前的Jenkins版本中哪个阶段失败 [英] Access which stage failed in previous Jenkins build
问题描述
我编写了一个Jenkinsfile脚本，该脚本获取在当前Github提交中是更新文档还是更新代码，并相应地开始所有阶段.如果只更新文档，则不会再次运行代码测试阶段.
I have written a Jenkinsfile script which gets whether documents are updated or code is updated in the current Github commit and starts all the stages accordingly. If only documents are updated I don't run the code testing stage again.
因此，现在如果以前的构建失败，并且现在在当前的Git中，仅文档被更新，那么它将不会运行代码测试阶段.因此，我希望有一种方法/方法来知道在上一次Jenkins构建期间哪个阶段失败了，如果需要，请运行当前的Jenkins构建.
So now if the previous build failed and now in the current Git commit only documents are updated then it will not run the code testing stage. So I want a method/way to know which stage failed during the last Jenkins build and if needed run the current Jenkins build.
例如，如果在先前的构建中代码测试阶段失败，那么我将需要为此构建运行代码测试阶段，否则，我可以仅运行文档压缩阶段.
For example if the code testing stage failed in the previous build, I'll need to run the code testing stage for this build, otherwise I can just run the documents zipping stage.
推荐答案
作为从詹金斯构建中获取失败阶段的一种解决方法，可以使用这种功能.我找不到更简单的方法来做到这一点.但是此代码需要在没有Groovy沙箱的情况下运行，或者您需要将许多Jenkins方法签名列入白名单(不推荐使用).还必须安装blueocean插件.
As a workaround to get failed stages from Jenkins build such function can be used. I could not find a simpler way to do it. But this code requires to run without Groovy sandbox or you need to whitelist a lot of Jenkins method signatures (which is not recommeded). Also blueocean plugin has to be installed.
import io.jenkins.blueocean.rest.impl.pipeline.PipelineNodeGraphVisitor
import io.jenkins.blueocean.rest.impl.pipeline.FlowNodeWrapper
import org.jenkinsci.plugins.workflow.flow.FlowExecution
import org.jenkinsci.plugins.workflow.graph.FlowNode
import org.jenkinsci.plugins.workflow.job.WorkflowRun
@NonCPS
List getFailedStages(WorkflowRun run) {
List failedStages = []
FlowExecution exec = run.getExecution()
PipelineNodeGraphVisitor visitor = new PipelineNodeGraphVisitor(run)
def flowNodes = visitor.getPipelineNodes()
for (node in flowNodes) {
if (node.getType() != FlowNodeWrapper.NodeType.STAGE ) { continue; }
String nodeName = node.getDisplayName()
def nodeResult = node.getStatus().getResult()
println String.format('{"displayName": "%s", "result": "%s"}',
nodeName, nodeResult)
def resultSuccess = io.jenkins.blueocean.rest.model.BlueRun$BlueRunResult.SUCCESS
if (nodeResult != resultSuccess) {
failedStages.add(nodeName)
}
}
return failedStages
}
// Ex. Get last build of "test_job"
WorkflowRun run = Jenkins.instance.getItemByFullName("test_job")._getRuns()[0]
failedStages = getFailedStages(run)
