Initially i installed 7.8.x.x and PR decoration didn’t worked on it, so i thought might be a bug in 7.8, so i installed latest version 7.9.x.x and still facing the same issue.
How it worked in 7.7 for you?
When you created a pull request, did the analysis happened with app itself OR did it trigger a jenkins job to perform the analysis and then results showed in github PR?
Make sure you set up your organisation to push Pull Request creation web hooks to Jenkins. The Folder Plugin then does all the magic
Then we have a shared library function that uses the env variable from GItHub Organsiation Folder and the pom.xml file to dynamically get all values for the sonar.properties file.
If you get issues let me know and I may be able to iron out your issues . Obviously as ours isn’t working at the moment I am not confident in our answers yet.
If you do get issues try increasing the log level to Debug or Trace on SonarQube. It seems some GitHub errors are only written in Trace (in the ce.log)
