title: intellij/activator/sbt are downloading dependencies previously downloaded by the other
body: <p>I'm not an expert with sbt so probably my question is a bit noob, but I've notice than when I create a project and download its dependencies with sbt, if I open the project with intellij, all the dependencies are redownloaded again, the same happen in the inverse orden intellij->sbt and also activator..</p>
  
  <p>my (poor) knowledge about sbt is than this use ivy and the dependencies are downloaded in ~/.ivy2/ folder...that is where sbt is downloading my deps, but seems than intellij is using other folder.</p>
  
  <p>personally I don't use so much activator, but I would like configure sbt and intellij for use the same ivy path...</p>
  
  <p>2)recently I publish finagle-postgre to my local ivy using sbt +publishLocal, I can check in my ivy folder</p>
  
  <pre><code> /home/yo/.ivy2/local/com.twitter/finagle-postgres_2.11/0.1.0-SNAPSHOT
  </code></pre>
  
  <p>but unfortunately intellij is unable to resolve this dependency, I try adding this line to my build</p>
  
  <pre><code> resolvers += Resolver.file("Local", file( Path.userHome.absolutePath + "/.ivy2/local"))(Resolver.ivyStylePatterns)
  </code></pre>
  
  <p>but seems not works</p>
  
  <p>3) the path where is downloaded the dependencies is related to which sbt-launch.jar file is used? How can I know what sbt-lauch.jar file is using sbt right now... </p>
  
  <p>thanks guys! </p>
