我知道我的这个问题已经被问过很多次了,我确实遵循了大多数答案,但没有一个对我有帮助。所以这是我的问题,每当我同步我的项目时,它总是失败。下面是 gradle 控制台的样子:
执行任务:[:app:generateDebugSources, :app:generateDebugAndroidTestSources, :app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies]
按需配置是一项孵化功能。增量java编译是一个孵化特性。 :app:preBuild UP-TO-DATE :app:preDebugBuild UP-TO-DATE :app:checkDebugManifest :app:preReleaseBuild UP-TO-DATE :app:prepareComAndroidSupportAnimatedVectorDrawable2420Library UP-TO-DATE :app:prepareComAndroidSupportAppcompatV72420Library UP-TO-DATE : app:prepareComAndroidSupportDesign2420Library UP-TO-DATE :app:prepareComAndroidSupportMediarouterV72300Library UP-TO-DATE :app:prepareComAndroidSupportRecyclerviewV72420Library UP-TO-DATE :app:prepareComAndroidSupportSupportCompat2420Library UP-TO-DATE :app:prepareComAndroidSupportSupportCoreUi2420Library UP-TO-DATE :app:prepareComAndroidSupportSupportCoreUtils2420Library UP-最新:app:prepareComAndroidSupportSupportFragment2420图书馆最新:app:prepareComAndroidSupportSupportMediaCompat2420图书馆最新:app:prepareComAndroidSupportSupportV42420图书馆最新:app:prepareComAndroidSupportSupportVectorDrawable2420图书馆最新:app:40准备ComGoogleAndroidGmsLibrary :准备ComGoogleAndroidG msPlayServicesAds940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesAdsLite940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesAnalytics940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesAnalyticsImpl940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesAppindexing940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesAppinvite940Library UP-TO- DATE :app:prepareComGoogleAndroidGmsPlayServicesAuth940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesAuthBase940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesBase940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesBasement940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesCast940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesCastFramework940Library最新:app:prepareComGoogleAndroidGmsPlayServicesClearcut940图书馆最新:app:prepareComGoogleAndroidGmsPlayServicesContextmanager940图书馆最新:app :prepareComGoogleAndroidGmsPlayServicesDrive940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesFitness940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesGames940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesGass940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesGcm940Library UP-TO-DATE :app:prepareComGoogleAndroidGmsPlayServicesIdentity940Library FAILURE: Build异常失败。

我已经从项目中删除 了 .gradle 文件夹,并且能够再次重建它。
