I've created a new project using fileLabeler as my labeler, and I also wanted the label to be received from one of the files in my project. As a result, the file for fileLabeler doesn't exist when project is first built. fileLabeler throws exception and prevents build to proceed.

  I suggest assign default label instead so that to give a chance for file to appear on "source control" phase of the build. Or maybe some attribute in configuration file to indicate, that file is expected to be there after project is get from source control.

  BTW, in such configuration label stably lags because file is updated _after_ the label to the project is assigned. It would be awsome to overcome this.
