Create Sonar Plugin - Scanner Basic - Save Issues 2

 Need to create a InputFile (org.sonar.api.batch.fs.InputFile) to save the issue. 

Retrieve the input file from the file system ( org.sonar.api.batch.fs.FileSystem) by mmatching name and the type of the file (MAIN)

    Currently we have two types (MAIN and TEST)

-----------

public static enum Type {
    MAIN,
    TEST;

    private Type() {
    }
}

----------------------

below is the sample code snippet to get the Input file

-------------------------------------------------------------------------------------

private void getResourceAndSaveIssue(final Violation violation, String fileName) {
    LOG.debug("Calling getResourceAndSaveIssue for file=" + fileName);
    LOG.debug(violation.toString());

    InputFile inputFile = fileSystem.inputFile(
            fileSystem.predicates().and(
                    fileSystem.predicates().hasAbsolutePath(fileName),
                    fileSystem.predicates().hasType(InputFile.Type.MAIN)));

    LOG.debug("inputFile null ? " + (inputFile == null));

    if (inputFile != null) {
        saveIssue(inputFile, violation.getLine(), violation.getRule().getId(), violation.getRule().getName());
    } else {
        LOG.error("Not able to find a InputFile with " + fileName);
    }
}
