Need help getting PR decorations working upgrading from 6.7.3 to 7.6

Hello all,

Previously on 6.73 we used the GitHub plugin for PR decoration via sonar.analysis.mode=issues. We are currently evaluating 7.6’s PR Analysis mode to see which our developers prefer. I believe I have everything correctly setup. Here are details:

SonarQube running latest version
I have tried this with both SonarQube Scanner 3.3.0.1492 and SonarQube Scanner 3.0.3.778.

We launch the scanner via Jenkins slave using this line:

/opt/sonar-scanner/bin/sonar-scanner -X -Dsonar.pullrequest.github.repository=repo/repo-name -Dsonar.pullrequest.branch=test-sonar76 -Dsonar.pullrequest.key=21811 -Dsonar.pullrequest.base=master -Dsonar.modules=backend

I think we have all of the correct switches to evoke that mode. In the output I see:

03:01:37.761 DEBUG: Found manual configuration of branch/PR analysis. Skipping automatic configuration.

However we go no decoration (I did setup the Pull Request section of SonarQube). I think these messages are related:

03:01:38.970 DEBUG: SCM Step is disabled by configuration
03:01:38.996 DEBUG: SCM information about changed files in the branch is not available
03:04:24.675 INFO: SCM Publisher is disabled

This is due to to sonar.scm.disabled being enabled on the server. When I disabled sonar.scm.disabled, we started getting this error:

03:26:29.737 ERROR: Error during SonarQube Scanner execution

I have updated all plugins to latest, then went from SonarScanner 3.0.3.778 to 3.3.0.1492 they both have the same issue once SCM scanning is enabled.

Any help would be greatly appreciated.
