If you don't see the report link in the output in the IDE, make sure to select the top-level node in the structured output panel.
The report will explain the errors in detail.
Perhaps, you forgot to add an `@Incubating` annotation or `@since` in the javadoc.

2. Accept the changes.\
If you are sure that the changes are intentional, follow the steps described in the report.
