有关Android Studio升级2.2后新建项目出现Error:Failed to resolve: javax.inject:javax.inject:1等问题解决

昨天下午更新的Android Studio 2.2，晚上宿舍断网了，后新建项目出现

Error:Failed to resolve: javax.inject:javax.inject:1
Error:Failed to resolve: javax.annotation:javax.annotation-api:1.2
Error:Failed to resolve: com.google.code.findbugs:jsr305:2.0.1
Error:Failed to resolve: org.hamcrest:hamcrest-library:1.3
Error:Failed to resolve: org.hamcrest:hamcrest-integration:1.3
Error:Failed to resolve: com.squareup:javawriter:2.1.1

问题。
对比新旧项目build.gradle(Module: app) ，发现删除

 androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
 })

问题完美解决。今天连上网本想再看看，新建项目后经过 Refreshing SDK 不用删除也没有出现这个问题。看来AS更新的不彻底啊
