Sonarqube branch results for long-lived branch not showing as expected

Question

Sonarqube Server Version 7.0 (build 36138)

Sonarqube Branch Plugin 7.0 (build 413)

sonar-maven-plugin:3.4.0.905

Java project

Sonarqube is set up with a master branch already.

As part of a Jenkins build job we execute the following command:

mvn sonar:sonar -Dsonar.host.url=<our host> -Dsonar.projectName=<project name> -Dsonar.projectKey=<project name> -Dsonar.branch.name=${BRANCH}

where BRANCH is set to the branch name we are building in Jenkins.

Analysis appears to work when we build our "develop" branch in that the develop branch appears if it isn't in Sonarqube and the timestamp for the analysis is correct on the server, but there are two issues:

1) I've set "develop" to be a long-lived branch per the instructions in https://docs.sonarqube.org/display/PLUG/Branch+Plugin by modifying the long-lived branch regex in the SQ server to be:

(branch|release|develop)-.*

but I only see the Issues and Code tabs on the "develop" branch display. And in the Jenkins job, I see the message:

[INFO] Branch name: develop, type: short living

which leads me to believe that develop is not being recognized as a long living branch.

2) There is no output in the Issues tab. Only the code tab shows anything. But the master branch output shows 225 issues, so I would expect the same list of issues in the develop branch (since they haven't been addressed).

Questions:

1. Do long living branches show all of the same output that you normally see for the master branch, including "Overview"?

2. Is there something that I need to do to specify the "develop" branch as long-living in the maven command above?

3. Any idea why the issues tab doesn't show anything?

Many thanks, Wes

Answer 1

In my opinion it is your regex you should check first. You are using the default (branch|release|develop)-.* notice that you have added hyphen(-) at the end.
So, sonar expects the branch name to be branch-, release- or develop-. In your case I believe the regex should be (branch|release|develop).*

Seems you hit this:
