Unable to create Scala class on IntelliJ

Question

I'm just starting to learn Scala. I have installed the Scala plugin for IntelliJ, and created a new Scala project. But when I right-click on the src folder to make a new Scala class, there is no option to do so. Am I missing something?

Answer 1

In IDEA 2016.2.5

From a new SBT or Scala project.

• Open Project Structure
• On the Project tab add your JDK (should also be visible in SDKs tab)
• Under Global Libraries add Scala SDK.

Sadly just adding this to your build.SBT does not impact the IDE behavior.

Answer 2

Right Click on the SrcScala folder :)

Answer 3

I just had this issue, also. It turned out that IntelliJ hadn't marked my src/main/scala folder as a "source" folder.

To do this: Project Structure -> Modules -> right click folder and Mark as "Source" (blue)

Similarly the src/main/test folder wasn't marked as a test folder. I was able to add scala classes after those folders were appropriately marked.

Answer 4

I had this problem everytime I created a new project with spaces in the name. eg "Hell Wev". Using "HellWev" or similar as a project name seems to work fine

Answer 5

I also faced same issue, the scala file options were not not visible in intellij Idea editor because Scala SDK was not installed. So you get rid of this issue after installing SDK for Scala.

1. Created new gradle project (java)
2. Add new module "scala" into /src/main/ and "Make Directory" as source ...

3. added dependencies into build.gradle:

   group 'example-scala'
   version '1.0-SNAPSHOT'
   
   apply plugin: 'java'
   apply plugin: 'scala'
   
   sourceCompatibility = 1.8
   
   repositories {
        mavenCentral()
   }
   
   dependencies {
      compile 'org.scala-lang:scala-library:2.12.6'
      testCompile 'org.scalatest:scalatest_2.11:3.0.5'
      testRuntime 'org.scala-lang.modules:scala-xml_2.11:1.0.6'
      testCompile group: 'junit', name: 'junit', version: '4.12'
   
   }
