Answer 1

TLDR，我认为这可能是因为网络问题，但您也可以使用jcenter（）和mavenCentral（）中存在的版本（如2.3.0）。

首先，你在jcenter（）和mavenCentral（）中有不同的版本。

在https://jcenter.bintray.com/com/android/tools/build/gradle/

中

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/

中

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非常适合我

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

Answer 2

我有相同的pb，因为我们在这里有代理，我在File＆gt;中配置了设置我不明白为什么Gradle一直告诉我连接超时。我已设法解决它在gradle.properties中添加HTTPS代理系统道具

 systemProp.https.proxyHost=<my proxy hostname>
 systemProp.https.proxyPort=<my proxy port>

我的gradle.properties只包含http.proxyHost / Port props ...

Answer 3

就我而言，注释掉gradle.properties中的代理设置即可解决问题。

#systemProp.https.proxyPort=8580
#systemProp.http.proxyHost=127.0.0.1
#systemProp.https.proxyHost=127.0.0.1
#systemProp.http.proxyPort=8580

Answer 4

在你的项目级别build.gradle文件检查jcenter（）是否存在，如果没有尝试上面的代码

   buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
