The purpose of this directory is to host a Gradle plugin that adds tasks for building the native binaries required by bdk-jvm/ bdk-android and building the language bindings files.

The plugin is applied to the specific build.gradle.kts files in bdk-jvm and bdk-android through the plugins block:

plugins {
    id("org.bitcoindevkit.plugin.generate-bdk-bindings")
}

It adds a series of tasks (buildJvmBinary, moveNativeJvmLib, generateJvmBindings) which are then brought together into an aggregate task called buildJvmLib.

This task:

Builds the native JVM library (on your given platform) using bdk-ffi
Places it in the correct resource directory
Builds the bindings file
