当我安装 Android Studio 2.3.3 并运行该项目时，我已经开发了 projet mobile，但出现此错误:

最佳答案
TLDR，我认为这可能是因为网络问题，但您也可以使用 jcenter() 和 mavenCentral() 中现有的版本(如 2.3.0)。
首先，jcenter() 和 mavenCentral() 中有不同的版本。
在 https://jcenter.bintray.com/com/android/tools/build/gradle/
2.2.0/
2.2.1/
2.2.2/
2.2.3/
2.3.0/
2.3.1/
2.3.2/
2.3.3/
在 https://repo1.maven.org/maven2/com/android/tools/build/gradle/
2.0.0/ 2016-04-07 17:59 -
2.1.0/ 2016-04-26 23:02 -
2.1.2/ 2016-06-06 18:06 -
2.1.3/ 2016-08-24 05:01 -
2.3.0/ 2017-03-06 22:09 -
其次，我认为您的错误可能是由于网络问题造成的。
wget https://jcenter.bintray.com/com/android/tools/build/gradle/2.2.3/gradle-2.2.3.pom 对我来说效果很好
$ wget https://jcenter.bintray.com/com/android/tools/build/gradle/2.2.3/gradle-2.2.3.pom

但是，ping jcenter.bintray.com:443 [jcenter.bintray.com/159.122.18.156] 对我来说似乎也失败了
