Exception in Intellij's SBT Console: not found: value ideaPort ideaPort in Global := 49516

Question

After a System Crash the sbt-console of Intellij 2019.1 can not start:

The following Exception is thrown:

<set>:1: error: not found: value ideaPort
ideaPort in Global := 49516

Strangely another project just works fine.

I removed .idea with no success.

Update: Different ideaPort, same Problem /solution

<set>:1: error: not found: value ideaPort
ideaPort in Global := 53318

Answer 1

I fixed by deleting the <project base>/project/target directory, as suggested here: https://youtrack.jetbrains.com/issue/SCL-15160#focus=streamItem-27-3373132.0-0

On Terminal: rm -r project/target

Answer 2

Disable Preferences | Build, Execution, Deployment | Compiler | Scala Compiler | Bytecode Indices as a workaround.

Follow this bug for the updates.

Or just hit the refresh button:
