pub build --mode=release never completes

[mjeffw]

Running "pub build --mode=debug" completes as expected.

Running "pub build --mode=release" never completes.

Turning on --verbosity=all shows the following messages being repeated over and over:

Hi @mjeffw thanks for filing.

I'm currently tackling some build-related issues as part of https://github.com/dart-lang/angular/issues/594, but until then I have the following suggestions:

• Remove angular/transform/reflection_remover

You can simply just rely on the angular transformer, and include it as an entry point:

transformers:
  - angular:
      entry_points:
        - web/main.dart
        - test/**_test.dart

If this works for you, please let me know. tl;dr, having multiple different transformer names in pub seems to use a lot of memory/CPU time, and it's not something AngularDart has the ability to fix.

/cc @chalin @kwalrath if we should document this further.

I think we should. dart-lang/site-webdev#658

Taking out angular/transform/reflection_remover worked, thank you!

For me that didn't work.

I also described this in #674

I had a lot of dart files in my "web" directory, also components for angular. Pub build hang until I moved most of the dart files into "lib."

After the build was running again , pub showed me errors again. Dartson was another cause of problems (It's seems not to be maintained anymore) so I'm trying to use built_value package now.
