Shield dependency in SBT


I am trying to import the shield dependency into my project (2.0.1).
My problem is that I am working with sbt, and I couldn't find how to import it.
I am using this as my reference :

I tried to add this to my resolvers:
"elasticsearch-releases" at ""
And this to my libraryDependencies:
"org.elasticsearch.plugin" %% "shield" % "2.0.1"

But it failed.

So the solution was to use only one % like this:
"org.elasticsearch.plugin" % "shield" % "2.0.1"
