Valo-Demo could not find artifact org.vaadin.themes:midsummer-night


I am trying to build
but there is a problem with getting midsummer-night dependency.
I cannot even locate that dependency anywhere.
Could you please let me know the url of repository where such midsummer-night dependency in version 1.0-SNAPSHOT is.

I was able succesfully build valo-demo before that commits on Apr 11, 2016.
