约定插件

// build-logic/convention/build.gradle.kts
plugins {
    `kotlin-dsl`
}

dependencies {
    compileOnly(libs.android.gradlePlugin)
    compileOnly(libs.kotlin.gradlePlugin)
}

// AndroidLibraryConventionPlugin.kt
class AndroidLibraryConventionPlugin : Plugin<Project> {
    override fun apply(target: Project) = with(target) {
        with(pluginManager) {
            apply("com.android.library")
            apply("org.jetbrains.kotlin.android")
        }
        
        extensions.configure<LibraryExtension> {
            compileSdk = 34
            defaultConfig.minSdk = 24
            
            compileOptions {
                sourceCompatibility = JavaVersion.VERSION_17
                targetCompatibility = JavaVersion.VERSION_17
            }
        }
    }
}

构建优化

# gradle.properties
org.gradle.parallel=true
org.gradle.caching=true
org.gradle.configuration-cache=true
org.gradle.jvmargs=-Xmx4g -XX:+UseParallelGC

# Kotlin
kotlin.incremental=true
kotlin.caching.enabled=true

# Android
android.useAndroidX=true
android.nonTransitiveRClass=true
android.nonFinalResIds=true

多模块设置

// settings.gradle.kts
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
}

include(":app")
include(":core:common")
include(":core:ui")
include(":core:network")
include(":feature:home")
include(":feature:detail")

依赖声明

// Feature module build.gradle.kts
plugins {
    id("convention.android.library")
    id("convention.android.compose")
}

dependencies {
    implementation(project(":core:common"))
    implementation(project(":core:ui"))
    
    implementation(libs.bundles.compose)
    implementation(libs.koin.compose)
    
    testImplementation(libs.bundles.testing)
}

构建命令

# Full build with timing
./gradlew build --profile

# Specific module
./gradlew :feature:home:assembleDebug

# Dependency tree
./gradlew :app:dependencies --configuration releaseRuntimeClasspath

# Clear caches
./gradlew cleanBuildCache
rm -rf ~/.gradle/caches

# Build scan
./gradlew build --scan

请记住：配置一次，每天优化。
