State

The project publishes experimental builds

Add the 'sellmair' maven repository

(settings.gradle.kts)

pluginManagement {
    repositories {
        maven("https://packages.jetbrains.team/maven/p/firework/dev")
    }
}

dependencyResolutionManagement {
    repositories {
        maven("https://packages.jetbrains.team/maven/p/firework/dev")
    }
}

Apply the Gradle plugin to your project

plugins {
    kotlin("multiplatform") version "2.1.21-firework.28" // <- Use special builds of Kotlin
    kotlin("plugin.compose") version "2.1.21-firework.28" // <- Use special builds of Kotlin/Compose Compiler
    id("org.jetbrains.compose")
    id("org.jetbrains.compose-hot-reload") version "1.0.0-dev.28.4" // <- add this additionally
}

Optional: Create a custom entry point to launch your hot application

// build.gradle.kts
tasks.register<ComposeHotRun>("runHot") {
    mainClass.set("my.app.MainKt")
}

💡The JBR can also be downloaded automatically by Gradle (foojay)

https://github.com/gradle/foojay-toolchains

// settings.gradle.kts
plugins {
    id("org.gradle.toolchains.foojay-resolver-convention") version "0.8.0"
}

Provide an Entry Point for your UI to hot-reload

@Composable 
fun App() {
    DevelopmentEntryPoint {
        MainPage()
    }
}
