o Adding source-scanner support, for selectively including source files to be compiled, or processed in some way. This is going to be a core-plugin facility, so it's in maven-plugin.
o Added support to maven-compiler-plugin for a source scanner to determine the files that actually need recompiling...currently based on lastModification date. o All of this stuff needs a good integration test, but it shouldn't mess any existing functionality up for now. Unit tests for the scanner stuff are included. git-svn-id: https://svn.apache.org/repos/asf/maven/components/trunk@163698 13f79535-47bb-0310-9956-ffa450edef68
