how to add scala-test support to intellij

Question

How do I install scala-test with intellij. The video on the intellij website shows them adding a library dependency with scala-test showing up on the list. I don't have that however as I'll need to install scala-test somehow first. The quickstart on the scala website just seems to have a link to a jar file. Do I configure the IDE in some way to point to that jar file as a global library?

Answer 1

No need for a global library. Intellij IDEA supports adding libraries to your project directly from Maven. Here's how:

1. Go to File -> Project Structure
2. Select the Dependencies tab
3. Click the + sign at the bottom to create a new library
4. Choose "New Library" and seleect "From Maven" to add a new library from the public Maven repository

This brings up a search dialog which you can use to find the Maven dependency you want. Try searching for "org.scalatest:scalatest" to get the list of scalatest libraries.

Answer 2

To install the latest version of ScalaTest and its dependencies in IntelliJ IDEA 2016.3.2, you need:

1. Visit http://www.scalatest.org/install (section To include ScalaTest 3.0.1 in your Maven project) to fetch a list of reqiered libraries full names with the following structure {groupId}:{artifactId}:{version}, e.g.

   • org.scalactic:scalactic_2.11:3.0.1
   • org.scalatest:scalatest_2.11:3.0.1

     Make sure that libraries names contain a Scala version you use in you project, i.e. above libraries are compatible with Scala 2.11 and not working with the new 2.12 version.

2. Go to File ⇒ Project Structure... or press Ctrl+Alt+Shift+S (Windows):
   

3. Go to Project Settings | Modules section and click on Dependencies tab. Then click + ⇒ 2 Library... ⇒ From Maven...:
   

4. Type in the full library name to install, then click Search button (or press Shift+Enter), select the library you need and click OK:
   

5. Repeat steps 3 and 4 until all dependencies are installed.
