我将Android Studio从3.0.1更新为3.1，并将Gradle从4.1更新为4.6
distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip
我收到此错误
Could not GET 'https://jcenter.bintray.com/commons-codec/commons-codec/1.6/commons-codec-1.6.jar'.
Received status code 504 from server: Gateway Time-out
我累了this solution，但仍然有错误。
