Source code is unavailable no matter what I do

I’m using #55 and everything seems to work fine, I see coverage results in jenkins with cool graphs, but I can’t manage to get the sources to display in jenkins.

Source

Source code is unavailable. Some possible reasons are:

This is not the most recent build (to save on disk space, this plugin only keeps the most recent build’s source code).
Cobertura found the source code but did not provide enough information to locate the source code.
Cobertura could not find the source code, so this plugin has no hope of finding it.
You do not have sufficient permissions to view this file.

There are a few related old issues: #29 #38

There is this closed issue: https://issues.jenkins-ci.org/browse/JENKINS-5235

My coverage.xml does have a valid path in sources:source tag. I was able to ls the sources from the path in the file.

        <sources>
                <source>/var/lib/jenkins/workspace/e-HTHYJUZDZMCL63QUXR6Q5QZPTK4AQEV3NNTYGGY2FQSB27WHP6ZA/MyAppName</source>
        </sources>

(only works with #55)

step([$class: 'CoberturaPublisher', coberturaReportFile: 'MyAppName/reports/coverage.xml'])

On my installation, I found out that only users with admin privilege can see the source code. Might be relevant to you.

Did just install the modified cobertura plugin and have the same issue here. It works with the old plugin when importing coverage.xml in a old style job, but not with the new plugin working in a pipeline job, so this is definitively not a user permission issue.
