@stokito I think you got the wrong enforcer-rules. This repo is for ono-extra-enforcer-rules. banCircularDependencies is defined by Mojo Extra-Enforcer-Rules: http://www.mojohaus.org/extra-enforcer-rules/. Please open your issue there: https://github.com/mojohaus/extra-enforcer-rules/issues

I know it can be confusing as both projects add extra enforcer rules to the standard rules.

Thanks @masooh I've created https://github.com/mojohaus/extra-enforcer-rules/issues/17 Sorry for inconvenience
