SBT failing to resolve dependency

I have the following simple SBT file

name := "TweetStream"
version := "1.0"

libraryDependencies += "org.apache.spark" %% "spark-core" % "1.5.2"
libraryDependencies += "org.apache.spark" %% "spark-streaming" % "1.5.2"
libraryDependencies += "com.google.code.gson" %% "gson" % "2.7"
libraryDependencies += "org.twitter4j" %% "twitter4j-core" % "4.0.4"

Somehow the SBT tool is adding a xxx_2.10 in the maven repository path resulting in unresolved dependencies as below.

I have tried deleting the following ivy folder as suggested in another post, but it didn't help.

~/.ivy2/cache$ rm -r commons-logging/

You don't specify Scala version, and it defaults to 2.10, which is probably not what you want. I don't know if the dependencies you want are published for 2.10.

Another thing is, Gson is not published like a Scala library, so you should rather add it via single %. Not sure about twitter4j, but the name also suggests it's a Java, not Scala library. Try something like this in your build.sbt

name := "TweetStream"
scalaVersion := "2.11.8" // provide Scala version
version := "1.0"

libraryDependencies += "org.apache.spark" %% "spark-core" % "1.5.2"
libraryDependencies += "org.apache.spark" %% "spark-streaming" % "1.5.2"
libraryDependencies += "com.google.code.gson" % "gson" % "2.7" // notice single `%` instead of `%%`
libraryDependencies += "org.twitter4j" % "twitter4j-core" % "4.0.4" // same here
