How can I specify the main class through CLI?

[tusharmath]

I want to specify the main class through cli. I have tried the following —

reStart/mainClass "example.HelloWorld"

But it doesn't work. What else can I do?

You can try

set reStart / mainClass := "example.HelloWorld"

but it would be nicer if we also had something like runMain.

Yes exactly!
