@paulodamaso @krzyk Is there any chance to fix this issue?
Today I found that this rule is applying to *.class files which are available in /src/test/resources.
I'm writing a lib that manipulates with bytecode and can't use qulice due to this rule :(.

I don't want to invent different hacks in order to avoid this violation... :(

[dgroup]

@paulodamaso the pull request also available, we can define white list or blacklist with extensions....

@yegor256 @dgroup issue can be closed, rule should be applied to java files only
