Why “could not find implicit” error in Scala + Intellij + ScalaTest + Scalactic but not from sbt

Question

I have this code that is working 100% from sbt , executing sbt test but throw a compilation error in Intellij Idea.

import org.         


        

Answer 1

Not sure if this was an IDE bug, but for me upgrading the IDE to latest didn't proved to be of any help. After wasting few hours here is my approach to resolve this error. Which states following.

could not find implicit value for parameter prettifier: org.scalactic.Prettifier

Solution :

In IntelliJ press Ctrl+Alt+Shift+S -> Modules -> Dependencies -> Search for 
org.scalactic:3.0.0.jar (Test scope) and most probably there would be 
another version as 2.x.x in compile scope. Right click on 2.x.x and select 
EDIT and then choose the 3.0.0 version in compile scope, and apply new 
settings.

P.S. Depending on your case there may be only one entry but make sure you 
use 3.0.0 in compile scope to get rid of that weird error.
