MVN build command overly complex

[sylvain-combe-sonarsource]

      run: |
        mvn -B test -Pcoverage verify org.sonarsource.scanner.maven:sonar-maven-plugin:sonar \
        -Dsonar.projectKey="demo:java-security" \
        -Dsonar.projectName="Java Web App" \
        -Dsonar.branch.name="${{ github.head_ref || github.ref_name }}" \
        -Dsonar.javaOpts="-Xmx8192m " \
        -Dsonar.scanner.debug="true" \
        -Dsonar.sources="." \
        -Dsonar.exclusions="src/test/java/**/*" \
        -Dsonar.tests="src/test/java" \
        -X

Should be fixed.
