android stadio 一直在下载download fastutil-7.2.0.jar 重新装了个系统，然后新装Android Studio导入项目时一直在下载 fastutil-7.2.0.jar原因是需要科学。所以改一下你的buil.gradlebuildscript { repositories { maven{ url = "http://maven.aliyun.com/nexus/content/groups/public/" } google() jcenter() } dependencies { classpath 'com.android.tools.build:gradle:3.1.2' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { maven{ url = "http://maven.aliyun.com/nexus/content/groups/public/" } google() jcenter() } }
