Short living branch shows only coverage estimated after merge

[dencowboy]

I’m using sonar 7.9 commuity edition in Docker and have checked out a sample project: GitHub - LableOrg/java-maven-junit-helloworld: A „Hello World!” sample written in Java that showcases very simple unit and integration tests..

I cloned the project and did the following for my master branch:

mvn clean install
mvn sonar:sonar -Dsonar.host.url=http://localhost:9000 -Dsonar.login=admin -Dsonar.password=admin

Now I see the coverage (94.6%) and testing in sonarqube. This is fine.
Now I created a branch from the master. I disabled some tests and run analysis for a short living branch.

git checkout -b feature/test
# disable some tests
mvn clean install
mvn sonar:sonar -Dsonar.host.url=http://localhost:9000 -Dsonar.login=admin -Dsonar.password=admin -Dsonar.branch.name=feature/test
# also tried:
mvn sonar:sonar -Dsonar.host.url=http://localhost:9000 -Dsonar.login=admin -Dsonar.password=admin -Dsonar.branch.name=feature/test -Dsonar.branch.target=master

Now I see the short living branch in the console. I see the coverage estimated after merge (which is lower than the original, as expected), but I do not see the coverage of the short living brach itself?:

What am I doing wrong?
Thanks!
