This is my base plugin that I use across my modding projects.

In your settings.gradle.kts:

pluginManagement {
    repositories {
        gradlePluginPortal()
        mavenCentral()
        mavenLocal()
        maven("https://maven.veriny.tf/releases")
    }
}

In your build.gradle.kts:

plugins {
    id("tf.veriny.gradle.base-plugin").version("0.7.0").apply(false)
}

subprojects {
    apply(plugin = "tf.veriny.gradle.base-plugin")
}

• Configures Java to use a Java 17 toolchain, as well as producing source and javadoc jars.
• Configures Kotlin to use Explicit API, a few compiler options, and to target Kotlin 1.9/JVM 17.
• Adds Maven Central, Maven Local, Mojang, Fabric, and Quilt repositories, and limits their groups to prevent trying to look up dependencies in places that don't have them.
• Applies the Spotless plugin for LF line endings and UTF-8 encoding, and applies Kotlin styling of 4 spaces and a licence header.
• Adds a publishing rule to publish to my maven releases repository.
