Can't make my jar work after being built with intellij
I am trying to create a jar file from my project in Intellij IDEA and after building the artifact I get the following error:
Error: Could not find or load main class com.trafficmonitoring.MatchPoint
I think that I have built the artifact correctly.
Image showing the contents of the jar
Image showing project structure and Manifest
Image showing how the artifact was generated
Image showing the sbt file
I can also see the MatchPoint class inside the jar as well as the manifest.
Any ideas of what could be going wrong?
The main method looks like this and it is scala/com/trafficmonitoring:
Main method
It has to be said though, that I have several objects with main method inside scala/com/trafficmonitoring but when I create the artifact I clearly select one of them as the main class.

I just tried this with a simple project (github.com/scala/scala-seed.g8) and it works for me: pasteboard.co/HObj9TE.png. We need to see 1) contents of generated JAR 2) Your Intellij artifact setup

Also, do you insist on generating the runnable jar by using IntelliJ's artifacts ? SBT's assembly plugin can do the same for you.

Actually this question is missing all the crucial information about your problem. What does your build.sbt look like ? How are you generating your jar ? How are you trying to run your jar ?

Screenshot tells us exactly, how he is trying to run the jar. We can also deduce, that he is using IntelliJ jar artifact to generate the jar. But he needs to show us, how the artifact was defined and what are the contents of generated jar

I am also able to build a hello world jar but when I try to do the same with my project it doesn't work. And no, it doesn't necessarily need to be generated using IntelliJ but as I am not experienced with sbt I prefer using IntelliJ
