Everyday when i turn on my laptop i need to organize the imports of my project, i mean, IntelliJ not recognize some imports of scala's playframework and i need to do all the time the next steps

1. sbt clean
2. close IDE
3. delete .idea folder
4. import scala SDK Module
5. file/ invalidate cache and Restart finally 3 o more times cleaning the project this works ok until i turn off my laptop and start again the next day

this is my screen and this is my Build.sbt and this is the error , i actually works with IntelliJ 2018.3.2 sbt 1.2.7 scala 2.12.8

IMPORTANT: my app was working ok without all the imports they aren't necessary only that you can see in the picture

Answer 1

Have you tried to prefix _root_ to all the Scala core packages? Like for example...

import _root_.scala.collection.JavaConverters._
import _root_.scala.concurrent.Future
