Missing com.megacrit.cardcrawl.cards
Hello. I am trying to create mods for Slay the Spire, so I followed a tutorial on GitHub for how to set up an ExampleMod class in IntelliJ. However, my ModTheSpire.jar does not contain com.megacrit.cardcrawl.cards or com.megacrit.cardcrawl.rooms, causing errors in the example code. I was thinking that maybe it was because it's not the latest version of ModTheSpire, but nowhere can I find the lastest version. The links go to the GitHub, and the GitHub points here, but there is no way to download anything from here...

Does anyone know why I wouldn't have a complete .jar, and how I can get one?
