Overall, the changes look good.

I have left few comments on what you could use

• Java Docs update on members, methods, classes
• Also we use Google-checkstyle https://google.github.io/styleguide/javaguide.html for formatting
• LOGs where necessary
• Also the Formatters have user-defined report-related contents, please use that
• Please create an issue to address this PR, we always associate every commit to the resolvement of an associated issue # and please associate it to a milestone
• Looking forward to more commits.

Apologies for taking time to review this. Also, we can try in parallel to set this up, how OSS Rules-of-play generate reports
via fosstars-rating-action in the future https://github.com/SAP/fosstars-rating-core/blob/master/.github/workflows/fosstars-rop-report.yml

@sourabhsparkala as I updated everything already: any updates to this?

[sourabhsparkala]

@ihrigb I will look into this. In the mean time, there seems to be checkstyle issues, could you please address them?

Thanks
Sourabh

The changes look good. A few Java Docs are missing. Please note the below-required changes

• I believe you need to add entries of Features and Scores in the associated *.java files in the folder https://github.com/SAP/fosstars-rating-core/tree/master/src/main/java/com/sap/oss/phosphor/fosstars/tool/format
• Checkstyle checks failing in the GitHub Checks https://github.com/SAP/fosstars-rating-core/pull/924/checks
