If you have any hint on why this is happening I can try to fix this

Sonar version : 8.8.0.42792
Plugin version : 1.7.0

I ran in the same issue on a grovvy project. But my Java project is still working.
I've a bit checked the stack trace and it fails there : https://github.com/mc1arke/sonarqube-community-branch-plugin/blob/master/src/main/java/com/github/mc1arke/sonarqube/plugin/ce/pullrequest/AnalysisDetails.java#L207 on decimalFormat.format(coverage).
I don't understand why though because coverage is a BigDecimal (so a Number) or is null. If it's null, it's not an Object.

Fixed in 1.8.0 of the plugin

@mc1arke i see the same issue with sonarqube 9.5 and plugin version 1.12.0.

couple of observations:

1 . works fine when change is in files whose language is recognized by sonarqube but when the pull request has changes to a shell script/Jenkinsfile it is not posting any comment maybe becuase there is no language for these files in sonarqube but the expectation is that it will post a success status check and sucessful comment in pr.
2. i installed shell check plugin and rerun it starts decorating the pull request.

question : if the language of the changes file is not available in sonarqube then plugin will not post any comment/status ?
