picocli
Picocli is a modern framework for building powerful, user-friendly, GraalVM-enabled command line apps with ease. It supports colors, autocompletion, subcommands, and more. In 1 source file so apps can include as source & avoid adding a dependency. Written in Java, usable from Groovy, Kotlin, Scala, etc.
Complex argument parsing needs to be auto-generated by libraries like picocli. Even if you need something custom, it'd be quicker to write an Annotation processor from scratch than editing that file.

GlobalPlatformPro
🌐 🔐 Manage applets and keys on JavaCard-s like a pro (via command line or from your Java project)
Project mention: Tillitis Security Key – Mullvad spin-off inspired by measured boot and DICE | news.ycombinator.com | 2022-09-19JavaCard is the answer for smartcards. You can find example card software all over github, and you're looking for the JavaCard SDK from Oracle and GlobalPlatformPro to program them: https://github.com/martinpaljak/GlobalPlatformPro. There's even an ant task around somewhere that allows you to use ant tooling. Blank cards with "developer"/default keys can be picked up pretty much anywhere.
Buy blank cards, write your applet, test in an emulator if you want, push to card, test for real with your software that talks to the card, profit. Be aware that if your goal is to write custom cryptography implementations in Java on the Javacard, these will be prohibitively slow. No need to take my word for it, Niels Duif did exactly this: https://research.tue.nl/en/studentTheses/smart-card-implemen...
