I have a .NET Core (console) app that I would like for a Java app to depend on. Essentially I would like to be able for the Java app to invoke a multi variable method in the .NET Core app and then pass the result back to the Java app. It would be nice if the .NET Core app could be embedded in the Java app. I have previously seen .NET Framework specific solutions to this problem, but since this would only be relevant on Windows, I would like a solution that also works on Linux.

You can't "embed" an app in an app. Is your console app a utility or a service? If it's a utility you can invoke it by calling out to the OS and receive the output. If it's a service it needs to expose an interface so you can call that with your choice of RPC.

In the past there were some technologies such as IKVM.NET and COM Interop wrappers but the former is defunct and the latter probably wouldn't work on Linux.
Since you own the .net core code, I would take a more modern microservice approach. I would design the .net core app to be a REST API running as a console app listening on a port. I'd have the Java application spin up the console app, invoke the methods passing JSON back and forth and then spit it down when complete.
