title: How resolve exceptions in Scala with IntelliJ?
body: <p>I am trying to run this <a href="https://github.com/salesforce/TransmogrifAI" rel="nofollow noreferrer">project</a> , I have added dependency in sbt file, My sbt file looks like:</p>
  
  <pre><code>name := "HelloScala"
  version := "0.1"
  scalaVersion := "2.11.8"
  libraryDependencies += "org.apache.spark" %% "spark-core" % "2.3.1"
  resolvers += Resolver.bintrayRepo("salesforce", "maven")
  libraryDependencies += "com.salesforce.transmogrifai" %% "transmogrifai-core" % "0.3.4"
  </code></pre>
  
  <p>Then I have copied the <code>Helloworld</code> folder from their repository, but having lot of issues. </p>
  
  <pre><code>Information:10/09/18, 12:01 PM - Compilation completed with 88 errors and 0 warnings in 15 s 624 ms

  <p>I tried to search about those issues and found it can be version issue, But I am not getting which version should I use, if there is version issue. 
  But if I am trying to run it from command line, it's working:</p>
  
  <pre><code>cd helloworld
  ./gradlew compileTestScala installDist
  ./gradlew -q sparkSubmit -Dmain=com.salesforce.hw.OpTitanicSimple -Dargs="\
  `pwd`/src/main/resources/TitanicDataset/TitanicPassengersTrainData.csv"
  </code></pre>
  
  <p>It's not working from IntelliJ , How can I resolve this issue?</p>
