I made a plugin for a custom language on SonarQube 7.9, starting from only a grammar and a lexer.
It is working fine, the custom rules I made are correctly detected.
However, I can’t find a way to report the code duplication. Reports always show 0 duplicated lines even if I copy paste the same big classes.
From the documentation it looks like it is something standard where the number of similar tokens, lines of codes, … can be parametrized. But how does it work for custom languages ? What should be implemented in the sensor to support code duplication detection ?
Thanks in advance and kind regards,
