At my company we started using CheckStyle, FindBugs, and PMD to check our code quality and unify our programming styles. These tools are very effective but unfortunately they have some overlapping rule sets.
Are there configurations available online which have removed the overlapping rules?
Of course, these default rule sets are not applicable to every project but it would be a good starting point for us. We could take this default (non overlapping) configuration and adapt it to our style instead of pruning the rule sets for duplicates first.
