Hi, I'm not sure if this is DDC related? The message says "Warning from Dart2JS" and the bazel build also seems to be using dart2js "WARNING: dart:mirrors support in dart2js is experimental"? Where is DDC being invoked?

jmesserly commented 7 years ago

I think this is probably a build/bazelify issue so moving to that repo

natebosch commented 7 years ago

Angular2 (or anything with transformers/codegen) aren't supported yet in bazelify.
