Android Studio重构项目时无法找到exoplayer:2.11.4依赖

问题现象 #

重构Android项目时出现依赖解析失败，错误提示找不到com.google.android.exoplayer:exoplayer:2.11.4，该依赖由第三方库com.github.HamidrezaAmz:MagicalExoPlayer:1.0.16间接引入，错误日志如下：

已尝试但无效的方法 #

• 在项目根目录build.gradle中添加JitPack仓库：

allprojects {
       repositories {
            maven { url 'https://jitpack.io' }
        }
    }

• 添加多个第三方仓库（包含已失效的Google Bintray仓库）：

allprojects {
    repositories {
        maven { url 'https://google.bintray.com/exoplayer/' }
        maven { url 'https://dl.bintray.com/android/android-tools' }
        maven { url 'https://dl.bintray.com/firebase/gradle/' }
        google()
        jcenter()
        mavenCentral()
        maven { url "https://jitpack.io" }
        flatDir {
            dirs 'libs'
        }
    }
}

可行解决方案 #

方案1：替换第三方库依赖版本 #

查找MagicalExoPlayer的最新可用版本，选择已将ExoPlayer依赖更新到可正常获取版本（如2.16+）的版本，修改app/build.gradle中的依赖：

implementation 'com.github.HamidrezaAmz:MagicalExoPlayer:最新可用版本号'

方案2：添加包含旧版ExoPlayer的镜像仓库 #

由于原Bintray仓库已关闭，可添加阿里云Maven镜像仓库（该镜像缓存了旧版ExoPlayer包），修改根目录build.gradle：

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://jitpack.io' }
        flatDir {
            dirs 'libs'
        }
    }
}

添加后点击Sync Now重新同步项目。

方案3：本地依赖ExoPlayer包 #

1. 手动下载exoplayer-2.11.4.aar包；
2. 将包复制到项目app/libs目录下；
3. 在app/build.gradle中添加本地依赖：

implementation files('libs/exoplayer-2.11.4.aar')

同步项目即可。
