API Changes

Command Line Interface

The command line options for PMD and CPD now use GNU-syle long options format. E.g. instead of -rulesets the preferred usage is now --rulesets. Alternatively one can still use the short option -R. Some options also have been renamed to a more consistent casing pattern at the same time (--fail-on-violation instead of -failOnViolation). The old single-dash options are still supported but are deprecated and will be removed with PMD 7. This change makes the command line interface more consistent within PMD and also less surprising compared to other cli tools.
