SonarQube analyze for short-lived branches doesn't work

[NJedrych (Norbert)]

Hello,

I am facing an issue with empty analyze of short-lived branch.
We are using Jenkins to trigger a job, branch is being created inside the project, however it looks like it is empty.

Similar issue:

Short-lived branch analysis seems to be empty

I’m using the gradle sonarqube plugin (2.6.2) to analyse a Java project, using CircleCI. It’s analysing the master branch fine, but when I use ‘-Dsonar.branch.name’ to analyse a feature branch the analysis runs through and the branch is created within sonarcloud, but the code is empty and there are no issues listed. Am I doing something wrong here? - run: name: SonarQube analysis command: | gradle sonarqube \ -Dsonar.login=$SONAR_LOGIN\ -Dsonar.br…

It works fine for long-lived branches.

It is same with sonar.branch.target passed in build or skipped.

Analyze is performed, files are being chosen into the analyze, but nothing visible in the UI.

Yesterday, i posted a Question here as well about a similar issue. Does my description of the problem match with that what you are experiencing?

Code coverage on branches does not break quality gate

Hello there I am currently evaluating SonarQube’s Developer Edition. We are thinking about switching to this license, because we want get analysis data of our branches, wich is not possible with the Community Edition. I am currently working with a test instance and an evaluation license. I am facing the following problem: Somehow, code coverage does not break our quality gate on branches. Our quality gate is configured like this: Condition Coverage on New Code is less than 80.0% Coverage o…

Thank you for your reply, but my issue seems to be different. In this case short-lived branch has been created, but not analyzed (no files, no bugs reported).

Analyze is performed, files are being chosen into the analyze, but nothing visible in the UI.

Can you please clarify what you mean by “looks like it’s empty”, and “nothing visible in the UI”?
For example, what do you see when you go to the Code tab on SonarQube?

Also, can you please run the scan in debug mode (use -X flag), and look for lines in the output like this:

[INFO] 11:36:32.749 SCM provider for this project is: git
[INFO] 11:36:32.749 2 files to be analyzed
[DEBUG] 11:36:32.759 Blame file some/path/...
[DEBUG] 11:36:32.759 Blame file another/path/...

The files mentioned by the “Blame file” lines are the ones detected as changed in the branch, relative to the specified -Dsonar.branch.target. If there are no such lines, then it’s no surprise if the analysis appears to be empty. And then, I would check the output of git diff --name-only the/target/branch... (the 3 dots at the end is not a typo). If this last command gives empty output, then the current branch has nothing new compared to the target, and therefore it’s expected that the analysis is empty.

Let me know your findings. If the above doesn’t help to understand what’s happening, then please include:

• a more complete snippet of the scanner output
• the exact scan command used, with all its parameters
• how do you checkout the branch before running the analysis: shallow clone?
