GitHub, Jenkins and coding standards
what sort of code style errors are you coming up against? CiviCRM's code style is very similar to Drupal's code style. I found some information about setting up NetBeans on CiviCRM's wiki, here:
https://wiki.civicrm.org/confluence/display/CRMDOC/IDE+Settings+to+Meet+Coding+Standards#IDESettingstoMeetCodingStandards-NetBeans

Hopefully these links provide the right answers. Otherwise let's update the wiki page!
