In IntelliJ my .main.kts scripts don't know about the Java stdlib - lots of:

Cannot access 'Object' which is a supertype of 'ObjectMapper'. Check your module classpath for missing or conflicting dependencies.

Cannot access 'Serializable' which is a supertype of 'ObjectMapper'. Check your module classpath for missing or conflicting dependencies.

I can't work out how to tell the script about them?
