Hi, Christian, took more than a few days, but now we finally do support custom license matchers with rat.
See http://ci.apache.org/projects/rat/apache-rat-plugin/examples/custom-license.html for details, but in short you must have something like the following in your POM: <licenses> <license implementation="org.apache.rat.analysis.license.SimplePatternBasedLicense"> <licenseFamilyCategory>YASL1</licenseFamilyCategory> <licenseFamilyName>Yet Another Software License (YASL) 1.0</licenseFamilyName> <notes></notes> <patterns> <pattern>Yet Another Software License, 1.0</pattern> </patterns> </license> </licenses> A snapshot is deployed to https://repository.apache.org/content/repositories/snapshots Jochen
