After upgrading the Junit plugin i am getting the following issue:
- If a job is only having only one build then it shows the "Test Result trends".
- If number of builds for a job is greater than 1, then it just shows the loading animation.
- This was working before the Junit plugin update.
I have seen all the issues opened regarding this but none solves my query.
Is this a bug in Junit plugin or Jenkins core itself?
Jenkins version : 2.249.2
Junit plugin : 1.43
[JENKINS-64129] Unable to see "Test Result Trends"

added a comment - We also had the same issue.
I am not sure we both have the exact same issue, but I noticed in the logs that we have this message:

We do use the same labels (build name) for our builds sometimes, especially in cases that some stage failed. I deleted the offending duplicate build, and the Test results then appeared fine.
Is it possible to support duplicate labels for builds?

added a comment - The same here, if pipeline job has duplicating build names, the bug occurs. After I have manually deleted all repeating builds, test results trends display correctly.

is there anything in the server logs?
what type of jobs?
