Android Studio Jetpack Compose项目出现androidx.appcompat重复类冲突

问题 #

使用Android Studio、Kotlin 1.7.10、Jetpack Compose开发，添加com.google.android.libraries.places:places:2.6.0依赖后，编译报错，提示大量androidx.appcompat相关类在appcompat-1.0.0和appcompat-resources-1.4.1模块中重复。

错误示例 #

Duplicate class androidx.appcompat.content.res.AppCompatResources found in modules appcompat-1.0.0-runtime (androidx.appcompat:appcompat:1.0.0) and appcompat-resources-1.4.1-runtime (androidx.appcompat:appcompat-resources:1.4.1)
Duplicate class androidx.appcompat.graphics.drawable.AnimatedStateListDrawableCompat found in modules appcompat-1.0.0-runtime (androidx.appcompat:appcompat:1.0.0) and appcompat-resources-1.4.1-runtime (androidx.appcompat:appcompat-resources:1.4.1)
（其余重复类错误信息省略）

已尝试无效操作 #

尝试排除places依赖中的AppCompat模块，但语法错误导致未生效：

implementation ('com.google.android.libraries.places:places:2.6.0')
  {exclude(group: 'androidx.appcompat', module: 'appcompat:1.0.0) }

解决方案 #

1. 修正依赖排除语法 #

你之前的exclude写法错误，模块名不能带版本号，正确写法如下：

implementation ('com.google.android.libraries.places:places:2.6.0') {
    exclude group: 'androidx.appcompat', module: 'appcompat'
}

2. 强制统一AppCompat版本 #

如果排除依赖后仍有冲突，在项目根目录的build.gradle中添加版本强制规则，让所有依赖使用同一版本的AppCompat：

allprojects {
    configurations.all {
        resolutionStrategy {
            force 'androidx.appcompat:appcompat:1.4.1'
            force 'androidx.appcompat:appcompat-resources:1.4.1'
        }
    }
}

或者直接在模块级build.gradle的dependencies中声明高版本AppCompat，Gradle会自动优先使用该版本：

implementation 'androidx.appcompat:appcompat:1.4.1'

3. 排查传递依赖 #

执行以下命令生成完整依赖树，确认哪些依赖引入了旧版本AppCompat，再针对性排除：

./gradlew app:dependencies

验证 #

修改后，执行Clean Project -> Rebuild Project，检查编译是否通过。
