I just upgraded the plugin to 2016.2.0 (I have the plugin update channel set to EAP) and I'm seeing this on every project refresh:
I have no proxy configured with the ide, so I'm a bit stumped.
I've tried with intellij builds:
IntelliJ IDEA 2016.2 EAP
Build #IU-162.1120.6, built on June 28, 2016
and IDEA 2016.2 RC (not sure which build #)
I've tried uninstalling and reinstalling the plugin and still receive the error.
Needless to say, I can't really do much work without it.
Any help is greatly appreciated.
