Try/Catch around Failing Plugin

[treads...@gmail.com]

Hi,

I'm trying to work around this bug where XUnit XMLs parsing crashes on Windows 10 nodes (https://issues.jenkins-ci.org/browse/JENKINS-34106)

I thought perhaps Pipeline steps might be the way to go and wrote this:

for (x = 0; x < 5; x++) {
    try {
        step([$class: 'XUnitPublisher', testTimeMargin: '3000', thresholdMode: 1, thresholds: [[$class: 'FailedThreshold', failureNewThreshold: '', failureThreshold: '', unstableNewThreshold: '', unstableThreshold: '0'], [$class: 'SkippedThreshold', failureNewThreshold: '', failureThreshold: '', unstableNewThreshold: '', unstableThreshold: '']], tools: [[$class: 'GoogleTestType', deleteOutputFiles: true, failIfNotNew: false, pattern: "_results/*/${config}/${arch}/tests/gtest*.xml", skipNoTestFiles: true, stopProcessingIfError: true]]])
        break
    } catch (any) { // XUnit fails on Win10, try again!
        echo "XUnit crashed, trying again!"
        sleep(5)
    }
}

But this simply isn't working:

...

12:08:16 [xUnit] [INFO] - Starting to record.
12:08:16 [xUnit] [INFO] - Processing GoogleTest-1.6
12:08:16 [xUnit] [INFO] - [GoogleTest-1.6] - 11 test report file(s) were found with the pattern '_results/*/release/x64/tests/gtest*.xml' relative to 'c:\jenkins\workspace\pipeline_component_2' for the testing framework 'GoogleTest-1.6'.
12:08:21 [xUnit] [ERROR] - The plugin hasn't been performed correctly: remote file operation failed: c:\jenkins\workspace\pipeline_component_2 at hudson.remoting.Channel@4ef7f3ea:HOSTNAME: java.io.StreamCorruptedException: invalid type code: 43
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: FAILURE

Shouldn't try/catch intercept the exception?  Does anyone have any other ideas about how I can force it to retry?

Thanks in advance!

only if the exception is thrown on that thread the try/catch is executing on. If any of the instructions in the try block spawn/use another thread,

exceptions thrown on that spawned thread will NOT be caught by your catch block.
