What Operating System are you using (both controller, and any agents involved in the problem)?

linux

Reproduction steps

open the coverage report on a finished build

Expected Results

it should show the Coverage trend

Actual Results

getting a 500 error

it seems projectDelta is null

probably the fileDelta here

uhafner commented 1 year ago

The only way that we get null are the parameters of the method. And these are all non-null by definition. That means they are deserialized from disk to null due to an error.

Is this a longer build history? Maybe some old builds did not get serialized correctly because one of the exceptions in the previous version? Or are all those builds from the latest version? Can you restrict the number of shown trend chart builds using the setup dialog?

Does this problem occur on a new job with a series of builds that use the latest coverage-plugin version?

viceice commented 1 year ago

it occurred on an old history. probably related to my previous reported issues 🙈

how can I configure the history, I'm using multi branch pipelines only for Gitea

uhafner commented 1 year ago

The problem is, that the configuration button is in the chart. But this chart is not visible due to the exception, isn't it?

Does the same problem also appear on the project page? There is also a trend chart... On this page you can use the configure button of any of the other charts to set the number of builds to consider.

viceice commented 1 year ago

that chart also shows the loading indicator and never completes

viceice commented 1 year ago

Seeing this on branch pipeline image

Also seen this exception

uhafner commented 1 year ago

This seems to be a new problem and not related to old serializations. I am using https://plugins.jenkins.io/commons-lang3-api/ as a dependency. It seems that one of the other plugins that shows results on the project page contains a copy of commons-lang3 in the build path. Your plugin list is really long so I do not see which of the other plugins might cause this problem. I'm not sure how we can find such plugins.

viceice commented 1 year ago

ok, found this:

jenkins-root/plugins> find . -name '*commons-lang3*'
./jenkins-jira-plugin/WEB-INF/lib/commons-lang3-3.6.jar

viceice commented 1 year ago

deleted the jira stuff, no longer used and jenkins says not installed

viceice commented 1 year ago

so can be one of these:

extended-choice-parameter is also uninstalled, so now deleted

viceice commented 1 year ago

sending upstream fixes

viceice commented 1 year ago

any workaround to fix without require manual plugin updates to snapshots?

uhafner commented 1 year ago

I don't think so :-(

viceice commented 1 year ago

maven-plugin fixed and released, need to wait for publish to jenkins 🙃

viceice commented 1 year ago

I've managed to resolve the lang3 dependency issue (removed blue ocean), but the NullPointerException is still thrown 😕

uhafner commented 1 year ago

Hmm, that means find . -name '*commons-lang3*' is empty for all other plugins?

viceice commented 1 year ago

yes, now only seeing multiple times the null pointer

Can you add some debug code, so i can send more detailed debug logs?

what about to catch that exception at a level, so we can see in logs which build / file is causing the error?

viceice commented 1 year ago

Interesting, it's working on one project. But the two colors have too less contrast. image

viceice commented 1 year ago

The difference is that the non working project uses relative paths inside the cobertura report and the working project uses absolute paths.

Do both projects have results of a previous serialization of an older version? Just to be sure that this is not a problem? Or does the problem occur with new projects and builds as well?

might be unrelated.

I released https://github.com/jenkinsci/code-coverage-api-plugin/releases/tag/v4.5.0: this should hopefully avoid the NPE but still suffers from a deserialization problem. I added a logger, maybe it helps to identify the problematic build.

viceice commented 1 year ago

how do I enable the finest log level for the plug-in? i never changed logging at Jenkins before 😇

viceice commented 1 year ago

v4.5.0 fixed the issue. coverage trend is now visible again. will check the logs for errors later

uhafner commented 1 year ago

Use http://localhost:8080/manage/log/ and add a new log recorder. There you can set the level to FINE and the class to io.jenkins.plugins.coverage.metrics.steps.CoverageBuildAction

Ok, good to see. In that release I also remove the serialization to commons lang3 in the XML files and replaced it with a custom serialization. So hopefully, the other error will not occur in future serializations anymore.

So I am closing this issue, feel free to reopen if required. You still can comment on this one if you get some logging details.

I now also configured the logger, but didn't see anything yet

You can try to remove the unreadable data. Hopefully, this will remove the issue as well.
