Duplicate NCLOC Metric Error for Files containing Defects

[bmorenc]

Hello,

We started seeing some failures in our SonarQube background process with the coverity-sonar-plugin at 1.7.3. We updated to 1.7.4 because of the Exception handling added however we are now seeing errors in the sonar scanner (run in our GitLab CI/CD pipeline)

This error only appears for files containing Coverity defects.

java.lang.UnsupportedOperationException: Can not add the same measure twice on <file_name_redacted>.cs: 
DefaultMeasure[
    component=<file_name_redacted>.cs,
    metric=Metric[
        id=<null>,
        key=ncloc,
        description=Non commenting lines of code,
        type=INT,
        direction=-1,
        domain=Size,
        name=Lines of Code,
        qualitative=false,
        userManaged=false,
        enabled=true,
        worstValue=<null>,
        bestValue=<null>,
        optimizedBestValue=false,
        hidden=false,
        deleteHistoricalData=false,
        decimalScale=<null>
    ],
    value=9,
    fromCore=false
]

With the logic in the scanFiles method of CoverityScanner.java: (lines 60-69)

It appears that 109 is now redundant and is the cause of the files containing defects to have duplicate NCLOC metrics added.

Please confirm and remove this redundancy. Thank you, Bryan
