纯Java项目接入Kotlin开发的AAR库：无需依赖Kotlin的对接方案咨询

Got it, let's walk through exactly how to get your Kotlin-built AAR into third-party developers' hands without making them install any extra Kotlin dependencies—all via file-based distribution, no Maven required:

First, you need to ensure your AAR packs all the Kotlin runtime and standard library code your library depends on. Open your library module's build.gradle.kts (or build.gradle if using Groovy) and tweak your dependencies to bundle Kotlin components into the final AAR:

For Kotlin DSL:

dependencies {
    // Use `api` instead of `implementation` for Kotlin stdlib to ensure it's included in the AAR
    api("org.jetbrains.kotlin:kotlin-stdlib:${kotlinVersion}")
    // Keep other library dependencies as needed—use `api` only for those you want embedded
}

android {
    // Optional: Ensure Kotlin module files are included correctly
    packagingOptions {
        pickFirst '**/*.kotlin_module'
    }
}

For Groovy:

dependencies {
    api "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
}

android {
    packagingOptions {
        pickFirst '**/*.kotlin_module'
    }
}

Using api ensures the Kotlin stdlib is exposed and bundled into the AAR, so developers don't need to add it themselves.

Generate the production AAR by running this command in your project root:

./gradlew :your-library-module-name:assembleRelease

Once the build completes, you'll find the AAR file at:
your-library-module-name/build/outputs/aar/your-library-module-name-release.aar

Just send this AAR file directly to third-party developers. They can integrate it into their project in a few simple steps:

1. Copy the AAR to their app's libs folder
   Create a libs directory in their app module (if it doesn't exist) and paste your AAR there.

2. Update their build configuration
   In their app module's build file, add the local libs directory as a repository and declare the dependency:

Kotlin DSL:

repositories {
    flatDir {
        dirs("libs")
    }
}

dependencies {
    implementation(name = "your-library-module-name-release", ext = "aar")
}

Groovy:

repositories {
    flatDir {
        dirs 'libs'
    }
}

dependencies {
    implementation(name: 'your-library-module-name-release', ext: 'aar')
}

Let developers know they don't need to add any Kotlin stdlib or runtime dependencies to their project—your AAR already contains everything required for your library to run. They can verify this by building their app without any Kotlin-specific entries in their build files.

A quick side note: If your library uses other third-party dependencies, you’ll need to decide whether to embed those too (using the same api approach) or inform developers to add them separately. But for your original question about Kotlin dependencies, this setup covers all bases.
