Android: Unable to resolve dependency for ':app@debugUnitTest/compileClasspath':

Posted 2022-11-16 yuyuan-bb

我按照ExoPlayer的github指引添加

implementation 'com.google.android.exoplayer:exoplayer:2.X.X'

发现根本run不起来，并报错如题

后来在stackoverflow找到了解决方案，来源为：https://stackoverflow.com/questions/46949622/android-studio-3-0-unable-to-resolve-dependency-for-appdexoptions-compileclas
出现问题的原因在于app含有buildtype但是library的依赖没有，所以我们需要添加一个matching configuration fallbacks

  buildTypes 
        release 
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        
        dexOptions 

            // release & debug is in project animators
            matchingFallbacks = ['release', 'debug']
        
        debug 

        
    

在dexOptions下增加callback即可
