SonarCloud metrics(coverage, code smells, vulnerabilities,..) on Pull Requests covers no lines

Tech stack :

  • Bitbucket Cloud
  • GCP - Cloud Build
  • sonar.branch.name=$BRANCH_NAME and sonar.branch.target=master
  • Java - Sprint Boot

the SonarCloud coverage reports generated on our pull requests have 0 lines covered when we follow the report towards its details page. I’ve noticed that none of the short-lived branches had any lines that were covered. Even if we introduce vulnerabilities or code smells on purpose, neither branch or PR analysis are picking this up.

Hey there!

Just to be clear about what you mean — do you mean that on the analyses of short-lived branches and pull requests, no files appear in the Code tab on SonarCloud?

Hi,

Thank you for the response!
Yes, that is correct and that’s probably also the reason why vulnerabilities, code smells, code coverage and so on are not displayed and picked up on branch and PR analysis.

Hey there.

I think it’s time to look in the scanner logs (preferably at DEBUG level, by adding -X to the scanner command or setting the analysis parameter sonar.verbose=true to see if anything is off. Here are the kind of logs you should be looking for on a branch/PR analysis.

# Check if there are any errors collecting changed files 
INFO: SCM collecting changed files in the branch
....
INFO: SCM collecting changed files in the branch (done) | time=324ms
DEBUG: SCM reported 1 file changed in the branch

# Make sure all files you expect to be analyzed are being analyzed and aren't ignored
INFO: 15 files indexed
INFO: 0 files ignored because of inclusion/exclusion patterns
INFO: 0 files ignored because of scm ignore settings

# Make sure the git repository is being detected
INFO: SCM Publisher SCM provider for this project is: git
INFO: SCM Publisher 1 source file to be analyzed

# Check if there are any errors collecting changed lines 
DEBUG: SCM reported changed lines for 1 file in the branch
INFO: SCM writing changed lines (done) | time=59ms

Checking for any WARN messages in the logs would also be a good step.

These are the logs corresponding to you’re proposal. The only one i could not find was the one about the SCM Publisher

No WARN messages found in the logs

Hey there.

It doesn’t look like you went up to DEBUG level with your logs – I would go back and do so and look for the lines like this:

DEBUG: SCM reported 1 file changed in the branch
DEBUG: SCM reported changed lines for 1 file in the branch

I would also check the 3 files that are indexed, and making sure that all the files you expect to see there are there.

My bad! Now i did the run with the debug switch enabled. It looks like it won’t pick up any of the files.
