build.dart expected errors ?

on master: https://travis-ci.org/angular/angular/jobs/66142657#L650

are those expected ?

These errors are coming from package:di, which is the original Angular.dart's DI code. I believe that is being brought in by benchmarking code to compare angular2 vs. angular.dart performance.

I don't know whether they are expected or not.

It seems like those are recent, I've first noticed them on your PR
https://travis-ci.org/angular/angular/jobs/66138141
There were not on alpha.26
https://travis-ci.org/angular/angular/jobs/65336394

(Not saying your PR is the root cause. Only adding refs for further investigations - could it linked to a dependency update ?)

I'm guessing b2596dd is the culprit, it adds empty .dart files and the errors sound correct to that situation.

Here is the build log for that commit with errors present: https://travis-ci.org/angular/angular/jobs/65435790#L652
and the same area in the commit before with no errors: https://travis-ci.org/angular/angular/jobs/65416977#L643

You probably know more about package:di than I do -- any idea why empty dart files might cause this situation?

Thanks for the analysis.

Might be because the transformers look for DI related code in the main or because there are multiple main. I'll take a look later this week.

Looks like this is a duplicate of #2380
