We’re using github-actions with a gradlew build to a monorepo. Sonar cloud does not indicate what project has the comment added refers to.
For context we have a few dozen projects (with unique project keys) in our mono repo. When sonar comments it appropriately only comments for the changed projects (maybe 2 per PR) and links to the correct sonarcloud.io project key but does not visibly display in the comment the project key.
The project name should get displayed (if it’s not, something isn’t quite right with your monorepo setup). You can pass a new project name, perhaps a more clear one (or one identical to the project key) by adjusting the sonar.projectName analysis parameter during an analysis of the main branch.
