Are these things we ship with our sources? Actually, most are pom.xml files. The test file is probably fine, I think it breaks if we add the header to it. I don't think we ship the docs code.

@LightGuard Those files are included in incubator-kie-10.0.0-rc1-sources.zip. Anyway, dependency-reduced-pom.xml is generated code, so we simply exclude it. ruleunit.drl.txt was okay to add license (doesn't break a test), so added. search-ui.js already has Mozilla Public License header
