I'm trying to use IntelliJ IDEA for my UnetStack Project.
I'm following this blog
https://blog.unetstack.net/using-idea-with-unetstack
I get this error when done following this:
Error: Could not find or load main class org.codehaus.groovy.tools.GroovyStarter
I had the same issue.
This happened to you because you ran your simulation as a groovy script and not as the configured application. Run it as application and groovyStarter will not even be used.
