What steps will reproduce the problem?

1. Install Dart IDE 1.0 from scratch
2. Create new Web Application project from IDE using Polymer
3. Run pub get
4. Get "Got dependencies!" message
5. Run pub build
6. Get message: Transformer library "package:observe/transformer.dart" not found.
7. >dir packages\observe
   2013-12-06 17:17 <DIR> .
   2013-12-06 17:17 <DIR> ..
   2013-10-17 17:43 2 225 html.dart
   2013-11-05 01:29 3 222 observe.dart
   2013-12-06 17:17 <DIR> src
   2013-11-08 02:13 436 transform.dart
   2013-11-08 02:13 15 315 transformer.dart
                  4 File(s) 21 198 bytes

As you can seen the package package:observe/transformer.dart is there.

What is the expected output? What do you see instead?
I'd like "pub build" to see the package that is there and build.

What version of the product are you using? On what operating system?
1.0, 32 bits
Windows 7 64

Please provide any additional information below.
I'm behind a proxy

Humm... sorry for that, but maybe that's a duplicate of 15161. Sort of (not same OS, but same symptom)

On the command line, removing HTTP_PROXY and HTTPS_PROXY env variables (windows) actually fixes the building problem.

It's a workaround: You need to build without proxy env variables; and to get/upgrade/... with the env variables.

Still a not-so-minor bug: the message "Transformer library "package:observe/transformer.dart" not found." is misleading: the file is not missing.

Looking at the proxy info in comment #­3, it looks like dart:io might try to use a proxy even when connecting using the loopback address.

I think this is a duplicate of issue #729. I've filed issue #772 to track the error message issue.
