Does the SDK selected here matter (there can be more than one known to server
depending on things such as flutter/non-flutter or strong/spec mode)? If so,
this might need to be more complex.

But if not, this should be "sdkManager.anySdk".

[scheglov, 2016/08/09 03:41:07]

Actually we almost don't need any DartSdk.
The only reason why we use it now is that DartParseTask also performs URIs
resolution.
We might want to fix this by extracting URIs resolution into a separate task and
drop using DartSdk here altogether.
