Issue while creating sbt project in IntelliJ

Question
1

I am trying to create a sbt project in IntelliJ. Project does get created with build.sbt as:
name := “scalalearning”

version := “0.1”

scalaVersion := “2.12.4”

But IntelliJ says ‘Cannot resolve symbol’ for all these 3 entries.

Also. console shows messages as:
/////////////////////////////////////////////////////////////////////
SBT ‘scalalearning’ project refresh failed

Error:Error while importing SBT project:

Infact, my earlier sbt projects too have stopped working. Sbt dependencies no more work it seems.

Any idea why IntelliJ behaves like this so frequently?

Hello,

What happens when you run SBT from the terminal?

Did you try to reinstall the IntelliJ Scala plugin?

Best, Oliver

I find it is best to quit IntelliJ, remove your .idea folder from the
project directory and re-import the SBT project. You won’t lose too much
most likely, just breakpoints, run configs, stuff like that, but at least
you’ll be working again.

4

sbt compile fails with unresolved dependencies.

5

Thats the only option I am left with. But IntelliJ keeps on doing things like this. It seems IntelliJ support for sbt has issues.

6

Maybe you first need to fix the dependency resolution?

7

Same dependencies used to work before.

8

What’s the error message if you run SBT in a terminal?

Have you tried something like “sbt clean”?

I solved the issue by deleting .idea folder and reimporting the project.
But it keeps returning back. Would look into ‘sbt clean’.
