Could not find com.android.tools.build:gradle:2.2.2
提问by WVrock
A friend of mine copy pasted a libgdx project folder on his pc and sent the project to me(through google drive). We are both using Android Studio. I downloaded and imported the project and it is working properly on the emulator. However it is not working on the desktop. On his pc, it works both in desktop and in the emulator.
我的一个朋友在他的电脑上粘贴了一个 libgdx 项目文件夹并将该项目发送给我（通过谷歌驱动器）。我们都在使用 Android Studio。我下载并导入了该项目，它在模拟器上正常工作。但是它在桌面上不起作用。在他的 PC 上，它可以在桌面和模拟器中运行。
When I try to run it in the desktop, Android Studio gives me this error message:
当我尝试在桌面上运行它时，Android Studio 给了我这个错误信息：
Error:Gradle: A problem occurred configuring root project 'bouncerGDX - Copy'.
> Could not resolve all dependencies for configuration ':classpath'.
> Could not find com.android.tools.build:gradle:2.2.2.
Searched in the following locations:
https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.2.2/gradle-2.2.2.pom
https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.2.2/gradle-2.2.2.jar
https://oss.sonatype.org/content/repositories/snapshots/com/android/tools/build/gradle/2.2.2/gradle-2.2.2.pom
https://oss.sonatype.org/content/repositories/snapshots/com/android/tools/build/gradle/2.2.2/gradle-2.2.2.jar
Required by:
:bouncerGDX - Copy:unspecified
How can I fix this? I have no experience with Gradle.
我怎样才能解决这个问题？我没有使用 Gradle 的经验。

UPD:
更新：
It seems can't resolve com.android.tools.build:gradle:2.2.2dependency for the classpath.
似乎无法解析类路径的com.android.tools.build:gradle:2.2.2依赖项。
For me, adding the jcenter to build.gradleresolves the issue:
对我来说，将 jcenter 添加到build.gradle解决了这个问题：
buildscript {
repositories {
mavenLocal()
mavenCentral()
jcenter()
}
or, alternatively, the line in build.gradle
或者，build.gradle 中的行
classpath 'com.android.tools.build:gradle:2.2.2'
can be changed to
可以改为
classpath 'com.android.tools.build:gradle:2.1.3'
^^^ this version exist in repo1.maven.org
^^^ 这个版本存在于repo1.maven.org
WRONG SUGGESTION:
错误的建议：
Resolve all dependencies by running gradle task (can be done from Android Studio's terminal):
通过运行 gradle 任务解决所有依赖项（可以从 Android Studio 的终端完成）：
For Linux:
对于 Linux：
./gradlew buildDependents
For Windows:
对于 Windows：
gradlew.bat buildDependents
Also, this commands might also help later
此外，此命令稍后也可能有所帮助
Linux:
Linux：
./gradlew cleanIdea idea
Windows:
视窗：
gradlew.bat cleanIdea idea

My fix for the same error was to configure Android Studio for the proxy I'm stuck behind.
我对相同错误的修复是为我被卡在后面的代理配置 Android Studio。
Android Studio + Gradle did not assume system proxy settings, at least not on my copy of macOS. Set your proxy settings in Preferences > Appearance & Behavior > System Settings > HTTP Proxy, save them and restart Android Studio. It then prompted me to set Gradle's proxy settings to match Android Studio's. Once I did this, no more error.
Android Studio + Gradle 没有假设系统代理设置，至少在我的 macOS 副本上没有。在 Preferences > Appearance & Behavior > System Settings > HTTP Proxy 中设置您的代理设置，保存并重启 Android Studio。然后它提示我设置 Gradle 的代理设置以匹配 Android Studio 的。一旦我这样做了，就不会再有错误了。
