# Build on Sid (Forky) using Debian's OpenJDK 23, Gradle via the Wrapper and secp256k1 installed via `nix profile install`.
# Sid/Forky should eventually have an LTS OpenJDK 25 which is our target version for a production-quality release of
# secp256k1-jdk. If we're lucky it might even get a Debian Gradle we can use. If so, we can make a Forky build that doesn't need Nix.
