IntelliJ + sbt -> no external dependencies - scala

Question

I am trying to set up IntelliJ IDEA with sbt for a Scala project. The external dependencies are specified in my build.sbt and also listed inside the IDE, as can be seen in the screenshot. However, I still get compiler errors that saying the respective symbol cannot be resolved. Can anyone point me into the right direction?
Contents of my build.sbt:
lazy val midas = (project in file("."))
.settings(
name := "test",
mainClass in assembly := Some("core.Service"),
assemblyJarName in assembly := "test.jar",
test in assembly := {},
libraryDependencies ++= Seq(
"org.slf4j" % "slf4j-api" % "1.7.25",
"com.typesafe.akka" %% "akka-actor" % "2.5.13",
"com.typesafe.akka" %% "akka-slf4j" % "2.5.13",
"com.typesafe.akka" %% "akka-remote" % "2.5.13",
"org.scala-lang.modules" %% "scala-xml" % "1.1.0",
"com.typesafe.play" %% "play-json" % "2.6.9",
"com.typesafe.slick" %% "slick" % "3.2.3",
"com.typesafe.scala-logging" %% "scala-logging" % "3.9.0",
"ch.qos.logback" % "logback-classic" % "1.2.3",
"ch.qos.logback" % "logback-core" % "1.2.3",
"com.mchange" % "c3p0" % "0.9.5.2",
"joda-time" % "joda-time" % "2.10",
"org.joda" % "joda-convert" % "2.0.1",
"net.sourceforge.jtds" % "jtds" % "1.3.1"
)
)
Still the dependencies for both, akka and joda-time cannot be resolved inside the IDE. The sbt compile from the command line works fine however.

Answer 1

joda-convert does not include org.joda.time.DateTime - you need "joda-time" % "joda-time" % "2.9.4" or so.
Once you have added this (and fixed your missing Akka import, maybe "com.typesafe.akka" %% "akka-actor" % "2.4.17"), you need to refresh the sbt project.
I press Shift, Shift to bring up "Search Everywhere" and type "sbt". Choose sbt under Tool Windows, then click "Refresh all sbt projects" (blue reload icon) in the sbt window. I close this window because it is not usually useful.
Hope that helps.
