I am trying to learn Kotlin by following the tutorial. I managed to get the plugin installed in Intellij. But I am not able to get the first exercise to run. When I click on the little checkbok it tells me

Failed to launch checking. See idea.log for more details.

(I created another blank project and type the same simple exercise in a scratch file and it works.)

Try to check the project's is linked to the right JDK. Open File/Project Structure/Project. Then select the correct Project SDK.

To me, this helped. But as others have pointed out, please, share your idea.log, which you can find at Help/Show log in [whatever text editor it's associated with].
