the task, apparently.

Update gradle to 2.11.

This fixes issues downloading from dmdirc.com over SSL, as
previous versions of gradle didn't support SNI.

forcing them to be resolved. Make circle use that.

This makes incremental build time ~2.5s on my machine.

Update clover/plugin versions.

Clover doesn't currently work due to a bug in lambda handling,

fix this.

Make dependencies operate recursively.
