"Failed to run dartdoc" without any output

[ganigeorgiev]

There seems to be some unknown error with dartdoc on package publishing.

I've recently submitted the following package - dygraph.dart and under the "Provide documentation" section is shown that dartdoc has failed to run, but there isn't any output.

I'm able to successfully generate locally the documentation with dartdoc v0.32.1, so I assume that the issue is pub.dev related:

Generating docs for library dygraph from package:dygraph/dygraph.dart...
Validating docs...
no issues found

Success! Docs generated into /path_to_lib/dygraph/doc/api

@ganigeorgiev: Thanks for reporting this! It looks like this is a bug in our dartdoc generator/ HTML customizer code:

NoSuchMethodError: The getter 'attributes' was called on null.
Receiver: null

At the same time I see a recent completion of retrying the dygraph 0.1.1 documentation generation, so it may be that this will be cleared once the caches clear. I'll take a look at it regardless...

I think I've identified the root cause: dygraph uses repository: in pubspec.yaml and no homepage:. dartdoc generated a slightly different HTML markup (with homepage it links to it, with repository it does not link to it), and we were not prepared for that. Filed a bug for it in dart-lang/dartdoc#2275

We'll also need to handle that gracefully on our side.

@isoos Thanks for the follow up. I've just published a new version (v0.1.1+1) with homepage and could confirm that the documentation was successfully generated.
