Javaexec class cast exception

I’m trying to run a Java program that is compiled in buildSrc.

When I do this I get the following exception. I’m probably doing something wrong, but I can’t see it.

Any help would be appreciated.

Thanks, Sean

It’s not clear to me when different forms of assignment (spaces, =, or :slight_smile: and which types are required.

I was only able to figure this out by looking at the gradle source code. Thanks for making that available.

It’s ‘args = [“foo”, “bar”]’, or ‘args “foo”, “bar”’, but not ‘args [“foo”, “bar”]’. The latter will try to index into the value returned by ‘args’.
