I'm using custom checks, I followed the procedure described on the web link you gave me. Everything now works correctly. Maybe I'm wrong but I think there's a mistake in this documentation: in the pom.xml example, dependencies containing custom developed checks are placed in the <build> <extensions> ... </extensions> </build> section. But when I run maven with my dependencies configured like that, these dependencies are not placed on the classpath and maven can't resolve my custom developed checks. If I place my dependencies containing custom developed checks in the <plugin> <dependencies> ... </dependencies> </plugin> section, it works fine.
