Jetpack Compose项目kotlin-stdlib重复类错误求助

使用Jetpack Compose和Kotlin开发项目时，添加新依赖后同步并运行应用出现以下错误：

执行任务':app:checkDebugDuplicateClasses'失败，提示在kotlin-stdlib-1.8.0（org.jetbrains.kotlin:kotlin-stdlib:1.8.0）和kotlin-stdlib-jdk8-1.7.10（org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.7.10）模块中发现重复类kotlin.collections.jdk8.CollectionsJDK8Kt。

1. 统一Kotlin Gradle插件版本 #

项目当前使用Kotlin 1.7.0插件，但部分依赖（如Jetpack Compose 1.3.3）默认依赖Kotlin 1.8.0标准库，导致版本冲突。修改项目级build.gradle中的Kotlin插件版本为1.8.0：

buildscript {
    ext {
        compose_ui_version = '1.2.0'
    }
    dependencies {
        classpath 'com.google.gms:google-services:4.3.15'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.8.0" // 升级到1.8.0
        classpath "com.google.dagger:hilt-android-gradle-plugin:2.42"
    }
}

plugins {
    id 'com.android.application' version '7.4.0' apply false
    id 'com.android.library' version '7.4.0' apply false
    id 'org.jetbrains.kotlin.android' version '1.8.0' apply false // 同步升级版本
    id 'com.google.dagger.hilt.android' version '2.42' apply false
    id 'com.google.gms.google-services' version '4.3.14' apply false
}

2. 统一Compose版本（推荐） #

项目中Compose依赖混用了1.2.0和1.3.3版本，建议统一为同一稳定版，避免潜在冲突。修改模块级build.gradle中的版本变量：

// Jetpack Compose
def compose_version = "1.3.3" // 统一为1.3.3
def kotlin_coroutines_version = "1.6.4"
def dagger_version = "2.44.2"

随后替换所有引用$compose_version的依赖项，确保版本一致。

3. 强制统一标准库版本（兜底方案） #

如果仍存在冲突，可在模块级build.gradle的dependencies块上方添加配置，强制所有依赖使用指定版本的Kotlin标准库：

configurations.all {
    resolutionStrategy {
        force "org.jetbrains.kotlin:kotlin-stdlib:1.8.0"
        force "org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.8.0"
    }
}

4. 清理缓存并同步 #

• 点击Android Studio右上角的Sync Project with Gradle Files重新同步项目
• 选择File > Invalidate Caches... > Invalidate and Restart重启IDE，清理旧缓存

冲突根源是项目配置的Kotlin插件版本（1.7.0）与部分依赖默认引入的Kotlin标准库版本（1.8.0）不一致，导致同一类文件在两个版本中重复存在。统一Kotlin版本后即可消除该冲突。
