"java.lang.IllegalArgumentException: Area already instantiated for: ProjectDefault (Template) Project" Idea-SBT plugin error

Question

I'm using intellij Idea 2019.2 ultimate edition. After I updated from 2019.1. 2019.2 edition I get below exception frequently.

I couldn't submit the report to SBT as the report button is always disabled.

How could I stop this exception other than disabling the plugin?

Answer 1

The plugin hasn't been updated in a while and has the following deprecation messaged on its website:

DEPRECATION JetBrains have recently added support for an SBT console to the IntellIJ Scala Plugin. This is now the recommended way to use SBT within IntellIJ. No new releases of this plugin are planned.

Go to the "Before launch" options of a Run Configuration, uncheck "Make" and choose "Run SBT Action / test-compile" to compile the project with SBT. This plugin does not generate or synchronize your IDEA project structure from the SBT build configuration. We recommend using the native support for importing SBT in IntelliJ. For more details, see: http://blog.jetbrains.com/scala/2013/11/18/built-in-sbt-support-in-intellij-idea-13/

I figured I don't need it anymore and uninstalled it. This doesn't really answers you question but I don't think this issue will be solved by the plugin maintainer.
