今天在Android Studio中编译工程的时候，遇见了一个奇怪的问题，报错如下：

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

诸如：

More than one file was found with OS independent path ‘META-INF/DEPENDENCIES’

......

大概意思就是工程生成了不止一个META-INF/proguard/androidx-annotations.pro文件，看起来是因为多个 jar 包里包含了同样的文件（proguard/androidx-annotations.pro），导致打包时因为担心相互覆盖问题而提示出错

在网上很容易就找到了解决方法，即在报该编译错误的module的build.gradle中加入如下配置项，排除掉中间生成的proguard/androidx-annotations.pro文件

    packagingOptions {
        exclude 'META-INF/proguard/androidx-annotations.pro'
        exclude 'META-INF/DEPENDENCIES'
        ....
    }

添加后的部分build.gradle文件如下：

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.demo.sportapp"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    //这是新添加内容
    packagingOptions {
        exclude 'META-INF/proguard/androidx-annotations.pro'
        exclude 'META-INF/DEPENDENCIES'

    }
}
