I’m stuck with this problem since several days, trying a lot of solutions such as reinstalling IntelliJIdea, sbt, scala, trying several versions of java.
After packaging a project with >sbt compile and >sbt package, I can’t make the produced jar file executed, I got this error:
Error: Could not find or load main class rockjvm_2.13-0.1.jar
Caused by: java.lang.ClassNotFoundException: rockjvm_2.13-0.1.jar
My project structure is on the picture
So I created a package named example within which I create an object named Playground. (sbt 1.5.5., Scala 2.13.7, IntelliJ IDEA 2021, openJDK 15.0).
Once packaged, I got the jar and wherever I install it and launch with >scala rockjvm_2.13-0.1.jar, I got those errors.
Could I have your help please,
Thank you very much,
