Hmm. There are no open bugs for that on the gulp-ng-annotate or browserify-ngannotate repos. https://github.com/Kagami/gulp-ng-annotate/issues and https://github.com/omsmith/browserify-ngannotate/issues

Feel free to open issues and I'm sure it will be addressed.

ng-annotate itself just produces output for input (stdin/stdout or via files) so it does not at all have any trouble participating in a "complex build environment".
