Hi,

I was just running the current m2e plugins with my fresh runtime
workspace in order to reproduce the issue #447460 before I go ahead and
try to fix it.

Unfortunately it's not running since takari aether connector makes use
of a class 'com.squareup.okhttp.Authenticator' which isn't available in
my classpath.

What am I missing here ? I mean I could try to lookup the artifact and
simply add the corresponding dependency to my configuration but since I
am the noob here I don't want to change such things like dependencies
without further knowledge.


Best regards

Daniel Kasmeroglu
