如何解决More than one file was found with OS independent path 'META-INF/proguard/androidx-annotations

今天在开发时导入androidx.annotation后出现了错误：

More than one file was found with OS independent path 'META-INF/proguard/androidx-annotations.pro' 

导入的build.gradle

dependencies {
    // https://mvnrepository.com/artifact/androidx.annotation/annotation
    implementation group: 'androidx.annotation', name: 'annotation', version: '1.1.0-alpha02'
}

错误：

解决方法：

修改build.gradle打包的时候忽略掉 androidx-annotations.pro

// app module下的gradle脚本
android {
    packagingOptions {
        exclude 'META-INF/proguard/androidx-annotations.pro'
    }
}
