Add support for XML config file and use outfile for results
Review Request #9516 — Created Jan. 22, 2018 and submitted
If a user has a complex ruleset file he can paste the whole configuration to the ReviewBot config. Redirect check result to output file as pmd could still print some warnings that will break any parsing of CSV output.
Used basic ruleset as cmdline parameter and saw correct results.
Paste a 6kb big xml config file and saw correct results.
