Jenkins 2.0RC1, Jenkins 1.6* LTS
Windows 2008r2, Windows 2012r2, Windows 7, Windows 10
When batch task is included in a Pipeline job it will hang on completion of the batch task. I can see in task manager that the job startup it logs data to jenkins-log.txt. The batch completes and I see in task manager that the batch is nolonger running. But Jenkins is still waiting for the task to complete. I do not see jenkins-result.txt writen to the workspace tmp durabletask directory. If I create the file manually or run the workflow-wrap.bat manually the task completes. This is an itermitent bug. Task might work 3 time then fail 5 times then work 8 times. No change to the system during this time. I am setting the job to run every min to see what the stats look like for longer run.
job:
node {
bat 'ping 127.0.0.1 -n 10'
echo 'batch completed'
}
Could be any command you want ping is just an easy one to have it take a little bit of time. And require nothing else installed on machine.
I see many other task like this I have tested on serveral differnt machines using a base install of Jenkins.

added a comment - stevenfoster In the control directory in the build agent's workspace for this job (where there's a jenkins-main.bat and jenkins-wrap.bat) do you see a jenkins-result.txt file, a jenkins-result.txt.tmp, or both?
I'm trying to figure out what actually triggered this because it did not fail any of our unit tests that should have explicitly covered this functionality.

added a comment - just the .tmp Sam Van Oort
added a comment - stevenfoster Okay, that means the "move" operation failed to rename the file, which should basically never happen. Would you be able to hop on #jenkins IRC briefly to discuss (I'm svanoort there)? It should be a quick and trivial fix but since we can't reproduce the issue in our own environment, it would be super-helpful to be able to see a case where it happened.

How can i still help you?

added a comment - lidl Don't worry about it, stevenfoster was thankfully available to help debug in an environment where this is reproducible (thanks!).
I'm attaching one more hotfix version for him to try out which should fully resolve the issue. durable-task.hpi

added a comment - This issue duplicates symptoms of JENKINS-50025 but the root causes are significantly different, so that is being tracked separately.

added a comment - lidl stevenfoster I'm closing THIS issue because while the result is the same this has a different cause and is resolved in JENKINS-50025.

lidl Does it work if you set 'returnStdOut: true', and if so, please try the attached hotfix and let us know if this resolves it.
