Having difficulty with jbang --interactive

[robin-a-meade]

I'm having trouble getting jbang --interactive to work.

Here's my trival script:

MyScript.java

package mypackage;
public class MyScript {
  public static void main(String[] args) {
    System.out.println("MyScript::main was called");
  }
}

I successfully ran the script:

[robin@laptop ~]$ jbang MyScript.java 
[jbang] Building jar for MyScript.java...
MyScript::main was called

I then tried jbang --interactive:

[robin@laptop ~]$ jbang --interactive MyScript.java
[jbang] You can run the main class `mypackage.MyScript` using: userMain(args)
WARNING: Using incubator modules: jdk.incubator.vector, jdk.incubator.foreign

jshell> userMain(new String[0])
|  attempted to call method userMain(String[]) which cannot be invoked until variable mypackage is declared

There seems to be two problems.

1. No classpath is reported by the /env command. I expected the MyScript.jar file that jbang built to be placed on the classpath.

2. the provided userMain method should be:

void userMain(String[] args) { mypackage.MyScript.main(args);}

not

int userMain(String[] args) { return mypackage.MyScript(args);}
