Secrets

SONAR_TOKEN – Required this is the token used to authenticate access to SonarCloud. You can generate a token on your Security page in SonarCloud. You can set the SONAR_TOKEN environment variable in the "Secrets" settings page of your repository.
GITHUB_TOKEN – Provided by Github (see Authenticating with the GITHUB_TOKEN).

Troubleshooting

Build error "ERROR: Could not find a default branch to fall back on."

If this error occurs in the build log, you can try this:

You may have to manually create the project in SonarQube/SonarCloud dashboard first. Make sure the Action input parameter sonarProjectKey (and sonarOrganization for SonarCloud) matches the ones in SonarQube/SonarCloud.
Make sure you have correct SONAR_TOKEN set. See Secrets above.

SonarQube/SonarCloud dashboard warning "Shallow clone detected during the analysis..."

If the SonarQube/SonarCloud dashboard shows a warning message in the top right ("Last analysis had x warning"), and the message is

"Shallow clone detected during the analysis. Some files will miss SCM information. This will affect features like auto-assignment of issues. Please configure your build to disable shallow clone."

it can be fixed by modifying the Git checkout action fetch-depth parameter:

- uses: actions/checkout@v2
      with:
        fetch-depth: '0'
