I am trying out scala for the first time and am following this page to set upmy first scala project : https://docs.scala-lang.org/getting-started-intellij-track/getting-started-with-scala-in-intellij.html
However despite this on creating a simple worksheet with println(“hello”) upon evaluation no results come up. What am I doing wrong ?
Have you pressed “Play” (green triangle) again after adding the new line and/or configured “interactive mode” via the wrench? If that doesn’t work, are there any error messages/popups when you press “Play”?
Yup, tried all that. Nothing seems to work.
No error messages as well.
Scala Worksheets do not work with newer Scala versions.
Scala 2.11.8 w/ JDK 8(1.8) worked for me personally, whereas 2.13.0 w/ JDK 8 gave zero output and zero error codes.
Other versions may work as well, but I haven’t tried.
There was a known bug that is supposed to be fixed in the subsequent builds. Could you please tell the version of the Scala plugin (Settings | Plugins | Scala)? Or better yet, please try to update the Scala plugin and see whether that fixes the problem.
Was on Scala Plugin version 2019.2.20; upgraded to 2019.2.23.
The issue now seems resolved.
Confirmed working with:
It’s strange, I could have sworn I checked for plugin updates a couple of days ago but none were present. Possibly due to the fact that my IntelliJ comes from a snap? Or maybe I am just inept.
Thank you for the help @pavelfatin
Still does not work for me: the same behaviour as reported by OP (no output)
Intellij EAP 2019.3 (193.3519.25)
Scala Plugin: 2019.3.4
@pavelfatin: do you have a link to this known bug? curious about the details.
Looks like a regression: I’m getting the same problem with
Everything worked until the latest IntelliJ upgrade.
First time it happens to me also with IntelliJ 2020.2, scala plugin 2020.2.27, scala sdk 2.13.3 and jdk 1.11.0 openjdk
