Answer 1

在您的项目级别 build.gradle 文件中检查 jcenter() 是否存在，如果不存在，请尝试上面的代码

   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
    }
}

Answer 2

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/

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 很适合我

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 3

我有相同的 pb，因为我们在这里有一个代理，我在文件 > 设置中配置了它我不明白为什么 Gradle 一直告诉我有连接超时。我已经设法解决它，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 道具...

Answer 4

就我而言，注释掉 gradle.properties 中的代理设置解决了问题。

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