In addition to programmatic output, you can generate a human-readable report in the HTML format by using the

A sample decorated diff
In addition to the sunburst diagram and other features of Qodana's HTML report, Clone Finder makes the analysis of code duplicates more helpful and convenient.
The detected clones are prioritized and displayed in the order of their importance.
When you expand an item, the duplicate code fragments are provided with decorated code diffs and are annotated with tags, licenses, languages, and file paths.

Clone Finder highlights similar lines and presents the following information to help you investigate the problem:
Lists all detected duplicate functions ranked by their importance.
Categorizes detected copies using 256 topics (see Figure 3 for a dendrogram of supported topics).
Lists licenses related to duplicate code fragments detected in the compared projects. By the way, to supplement this feature, we are working on another tool that will list the licenses for third-party libraries used in the queried project and warn about incompatibilities between the queried project's license and third-party licenses. Stay tuned!
License mismatch warnings
Displays a warning when the licenses in duplicate code fragments are different.
Displays the programming language of the clones. The EAP version of Clone Finder supports PHP, Java, and Kotlin.
