Not detecting newly added files in sibling dir (such as ../../src/main/webapp/asset/)

[JohnWu-Pro]

Context

I'm using grunt-maven-plugin for my project. The project directory structure is as follows

PRJ_ROOT/
   src/main/webapp/asset/
      app/
      test/
      ... ...
      Gruntfile.js
      package.json
   target/
      grunt/
         app/
         test/
         ... ...
         Gruntfile.js
         package.json
      WAR-FILE-NAME/

All contents in src/main/webapp/asset/ are copied into target/grunt/ when start working. And every change in src/main/webapp/asset/ should be synchronized to target/grunt/ after that. Grunt base directory will be target/grunt/.

With the following code

    watch: {
      maven: {
        files: ['../../src/main/webapp/asset/**']
      }

and

  grunt.event.on('watch', function(action, filepath, target) {
    grunt.log.debug('grunt.event.on.watch: '+target+', '+action+', '+filepath+' ...');
  });

Issue

Event on file added (by creating new file or by renaming an existing file) is never triggered. This issue is related to issue #282, but different.
