PackageResolver fails silently

[ndahlquist]

We have an issue similar to #82:

./gradlew resolveAllDependencies
Parallel execution with configuration on demand is an incubating feature.
propsFile exists -true
Support library repository outdated. Downloading update...

FAILURE: Build failed with an exception.

One problem is that the sdk download is failing, but no error output is shown by the plugin. It probably makes sense to print a message or throw an exception if the download fails.

The cause of this issue appears to be this, which may be related to #81, though I'm not sure exactly what's going on here:

This might be a related: https://code.google.com/p/android/issues/detail?id=36941.

Also, the sdk-manager-plugin appears to be correctly checking the exit code, so it appears that the android update command is returning 0... nice.
