When using the google_oauth2_client package (http://pub.dartlang.org/packages/google_oauth2_client) pub get/upgrade now seems to fail. This worked until recently.

I have attached the output from "pub --verbose get".

Actually, this may be an interaction between the google_oauth2_client and polymer packages. Adding one or the other is fine but adding both causes the failure.

I have the same problem but with the combination of spectre and polymer. This user has the same issue, too: https://github.com/johnmccutchan/spectre/issues/129

I'm hitting this pub get error as well.

How to reproduce:

The "incompatible version constraints" error is different. That's like a real version conflict that's being reported incorrectly. The reporting issue has been fixed, but I'm unsure if the fix has made it into a released SDK yet.

The "connection closed" error is trickier. Mark, does this reproduce in an empty project with just polymer and google_oauth2_client in the pubspec?

Yes it does seem to.

I'm not sure exactly which constraint is the ultimate cause of the conflict, but I did figure out that if I remove the version constraints on:

  logging: any # '>=0.9.0 <0.10.0'
  polymer: any # '>=0.9.0 <0.10.0'
  path: any # '>=0.9.0 <0.10.0'
dev_dependencies:
  hop: any # '>=0.28.1+2'
  unittest: any # '>=0.9.0 <0.10.0'

Then pub is able to find a good set of dependencies for spectre. My guess is that it's stuck on an older version of hop or maybe unittest, that eventually ends up forcing a version of barback too old to work with your current SDK.

To fix this, I think spectre just needs to upgrade itself to newer versions of its dependencies. Because pub uses barback, your Dart SDK will require certain versions of it. As you upgrade to newer Dart SDKs, that forces you to upgrade your dependencies if they ultimately end up depending on barback (which polymer does).

I'm going to close this bug out. I think there are a few things going on here:

1. You're getting a connection closed error. That, I believe, is just a transient networking error, and not a bug in the pub code.
2. The error message is confusing/wrong. This was a result of two bugs that are fixed on bleeding edge now.
3. There's some nasty dependency constraint in spectre's graph that's forcing it to do a ton of backtracking. This isn't a bug, it's just pub struggling to find a good solution to a hard problem. Upgrading spectre to use newer versions of its dependencies should help.

So, I could be wrong, but I don't think there's anything here we need to take action on (that we haven't already). If I missed something, though, please do let me know.

So does an empty project with just polymer and google_oauth2_client in the pubspec work for you? I'm still getting the same issue with this, and have been consistently for a few days, so I can't see it being a transient networking issue.

Or is this what has been fixed on bleeding edge?

The same for me with dart-polymer-dart-examples which has a dependency on google_oauth2_client. I suspect their 'path' dependency '<=0.10.0'.
I have posted an issued for google_oauth2_client to publish an updated release.
