title: sbt unresolved dependency issue
body: <p>I am trying to run this sbt project (based on play framework 2.4)
  <a href="https://github.com/pac4j/play-pac4j-scala-demo" rel="nofollow">https://github.com/pac4j/play-pac4j-scala-demo</a></p>
  
  <p>I am using the "activator run" command. My activator version is 1.3.6</p>
  
  <p>I do see the project in the default maven repo that sbt uses. But, the log above seems to indicate that it was not found.</p>
  
  <p><a href="https://repo1.maven.org/maven2/com/nimbusds/nimbus-jose-jwt/" rel="nofollow">https://repo1.maven.org/maven2/com/nimbusds/nimbus-jose-jwt/</a></p>
  
  <p>I tried clearing the ivy cache directories. But, that didn't seem to help.</p>
  
  <p>Output</p>
