Repro steps.

After upgrading to 1.3.0-rc.3 and doing some bad things, ng serve outputs:

webpack: Compiling...
webpack: Compiled with warnings.

But no warnings are printed 😞

(I encountered the issue with there changes, but any changes creating warnings should do.)

The log given by the failure.

N/A

(Hm...or maybe there are no warnings and the message is wrong. Not sure how to find out.)

[filipesilva]

There are errors. Might be just a circular dependency error, but it exists. I had similar trouble last week.

[gkalpak]

Yeah, they were circular dependency warnings. If there are errors too, the warnings are shown along with the errors. But if there are only warnings, nothing is shown.
