I seem to have been encountering this problem: http://stackoverflow.com/questions/17944108/maven-compiler-plugin-always-detecting-a-set-of-sources-as-stale The Apache parent POM (version 14) mandates version 3.1 of the compiler plugin, which is affected. I found when I tried the workaround of setting useIncrementalCompilation to false that the problem was avoided. If anyone else sees this, maybe the workaround will help. A good way is including -Dmaven.compiler.useIncrementalCompilation=false to MAVEN_OPTS. -- // Bill Havanki // Solutions Architect, Cloudera Govt Solutions // 443.686.9283 --001a11c2ef6e80590f04f8afd974--
