There's a little magic hidden by Gradle that devs would have to reverse engineer to understand correctly. Ideally we have a set of rules that, if any Java process follows, you can reasonably expect it to work. \r\n\r\nI recently tried to create the most bare-bones, minimal Java bot I could make using Maven as the build tool. Here's what I did: \r\n1. Created a standalone directory (under source control or not) for `bot.cfg`, `bot-appearance.cfg`, and `bot-module.py`; this is data that, once updated to reflect my own values and ingested into the RLBot UI, largely remains unchanged. \r\n1. Created the maven project with a single `pom.xml` and three classes: `Main`, `BotImpl`, and `PythonInterface`. That's it. \r\n1. Ensure the resultant jar has transitive dependencies packaged correctly. \r\n1. Ensure the resultant jar is executable.\r\n1. Ensure the system property `jna.library.path` is set to a directory with `RLBot_Core_Interface.dll` in it. In my case I'm just calling `System.setProperty` in `Main` to some stable, external directory (for now). \r\n\r\nDoing the above resulted in a working bot controller without any Gradle assumptions. I can rebuild and restart the jar completely independent of the `cfg` files or python module and everything keeps working.
