KotlinxSchemaPlugin

Gradle plugin for generating JSON schemas using KSP2.

This plugin invokes KSP2 programmatically without applying the Google KSP Gradle plugin. It configures KSP tasks for each Kotlin compilation and generates schema extension properties.

The processor generates extension properties on KClass that provide JSON schema strings:

• KClass<T>.jsonSchemaString: String - JSON schema as a string

• KClass<T>.jsonSchema: JsonObject - JSON schema as a JsonObject

Generated files are placed under build/generated/kotlinxSchema/.

Usage:

plugins {
    kotlin("multiplatform") version "2.2.21"
    id("org.jetbrains.kotlinx.schema.ksp") version "0.0.4"
}

kotlinxSchema {
    enabled.set(true)  // Default: true
    rootPackage.set("com.example")  // Optional: filter by package
    withSchemaObject.set(true)  // Default: false, enables jsonSchema JsonObject property
}
