scp plugin doesn't work for multi configuration project

I am trying to use scp plugin under multi configuration project without much
success. First time when I start the build, it never finish uploading even after
5mins and the project is just blinking. I decided to kill the project.

During my 2nd attempt at least I got this error in my log. BTW single
configuration seem to be working just fine.
