Solace

A Kotlin extension library for the Sponge ecosystem.

FAQ

Q: What's the difference between this library, and similar ones already available?

In Solace everything is inline'd, making it easier for Ore reviewers to decompile and read projects which use Solace.

Also, even though Solace shades the Kotlin standard library and runtime into its jar, it does so without causing issues with other plugins who do the same, because it relocates Kotlin to solace.kotlin.

Then, the only additional thing that projects that use Solace have to do, is to relocate Kotlin references itself to solace.kotiln.

Gradle Setup

To use Solace, your build.gradle should look similar to this:

plugins {
    id "org.jetbrains.kotlin.jvm" version "<KOTLIN VERSION>"
    id "org.jetbrains.kotlin.kapt" version "<KOTLIN VERSION>"
    
    id "com.github.johnrengelman.shadow" version "2.0.4"
}

configurations {
    compile.extendsFrom(kapt)
    compile.extendsFrom(shadow)
}

repositories {
    mavenCentral()
    maven { url "https://repo.spongepowered.org/maven/" }
    maven { url 'https://jitpack.io' }
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8:<KOTLIN VERSION>"
    
    kapt 'org.spongepowered:spongeapi:7.1.0-SNAPSHOT'
    
    compile 'com.github.xDotDash:solace:<LATEST SOLACE VERSION>'
}

shadowJar {
    configurations = [project.configurations.shadow]

    relocate 'kotlin', 'solace.kotlin'

    classifier = null
}

build.dependsOn(shadowJar)

compileKotlin {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

NOTE: We aren't actually using the shadow plugin to shade Kotlin. We are only using it to relocate references in our code, to use Solace's shaded Kotlin version.

Next:

Simply add Solace as a dependency in your @Plugin like so:

@Plugin(id = "my-plugin", dependencies = [
    Dependency(id = "solace", version = "3.4.0")
])
class MyPlugin

Finally, for Server Admins to use your plugin, they must now plop the Solace jar for your required version into the mods/plugins folder as well.
