DartEditor Pub Build google app engine

Question

I've coded a webapp in Dart. On server side I'm using DartForce MVC framework and on client side I'm using AngularDart. If I build in DartEditor I received this error

If I build same project into shell with

pub build

into my project folder and this produce an incomplete build: only web folder is generated.

This is my pubspec.yaml

name: dartrest
dependencies:
  angular: 1.0.0
  appengine: '>=0.2.4 <0.3.0'
  browser: any
  forcemvc:
    git: 'https://github.com/ForceUniverse/dart-forcemvc'
  http_server: '>=0.9.3 <0.10.0'
  logging: '>=0.9.0 <0.10.0'
  web_components: '>=0.9.0 <1.0.0'
dev_dependencies:
  mock: '>=0.11.0+2 <0.12.0'
  unittest: '>=0.11.0+5 <0.12.0'
transformers:
- angular:
    dart_sdk: /usr/lib/dart
    html_files:
    - lib/component/custom.html

Any ideas?

Can you please add your `pubspec.yaml` to your question. – Günter Zöchbauer Dec 03 '14 at 09:52 — Günter Zöchbauer, Dec 03 '14 at 09:52

Seems to be a issue with DartEditor to pass specific folders to the pub build command. Can you please create a bug report at http://dartbug.com/new.

It is fine if only the build/web folder was created.
The server code can be deployed as is. There is an experimental dart2dart option (see Run Dart WebApp on Apache Server) but for the way development for Managed VMs is currently set up, deploying the bin directory without building is just fine (default by gcloud preview app run app.yaml).

Update

Because transformers can be important for server side code as well it makes sense to run pub build web bin but just the Dart2JS transformer doesn't make sense for bin.

A workaround is to add this transformer configuration

transformers:
- $dart2js:
    $exclude: bin/**.dart

to your pubspec.yaml file.

As far as I know the $dart2js transformer should be the last in the list if you have others (like angular, di, smoke, ...)

Into DartEditor there is a commend `Run > Pub Build (generate JS)`, if I run this I've problem above. Into shell I lunch this command `pub build` in my project folder and all works good but the new build folder seems incomplete. – Claudio Pomo Dec 03 '14 at 10:01
I'm using AngularDart on client side. This is an example: https://github.com/angular/angular.dart.tutorial/tree/master/Chapter_06 If I run Pub Build into Dart Editor on this project a new build folder is created with all elements. – Claudio Pomo Dec 03 '14 at 10:10

The problem is just with DartEditor to invoking `pub build` with something like `pub build web bin` instead of just `pub build` – Günter Zöchbauer Dec 03 '14 at 10:12
