      Description

      <groupId>org.apache.drill.tools</groupId>
      <artifactId>drill-fmpp-maven-plugin</artifactId>

      has builtin verification if the generated files differ from the results of previous generation.
      It saves compile times, and it creates no risks.

      It enables to improve pom.xml as well (we can remove generate-parser build profiles)

      Benchmark: mvn test-compile -Dcheckstyle.skip=true
