Repeated executions of "mvn install -DskipTests -Dcheckstyle.skip=true" of
https://github.com/apache/incubator-calcite
with <useIncrementalCompilation>false</useIncrementalCompilation> are _faster_ than in default mode.

The issue is described here:
  http://stackoverflow.com/questions/17944108/maven-compiler-plugin-always-detecting-a-set-of-sources-as-stale
  https://jira.codehaus.org/browse/MCOMPILER-209
