强制Gradle使用HTTP而不是HTTPS

问题描述

我正在尝试构建react-native android应用程序，作为依赖我看到我有gradle，但无法加载构建。
错误消息：

  *出错：
配置根项目'MobileApp'时出现问题。 
>无法解析配置'：classpath'的所有依赖关系。 
>无法解析com.android.tools.build:gradle:1.3.1。 
要求：
：MobileApp：未指定
>无法解析com.android.tools.build:gradle:1.3.1。 
>无法获取资源'https://jcenter.bintray.com/com/android/tools/build/gradle/1.3.1/gradle-1.3.1.pom'。 
>无法GET'https://jcenter.bintray.com/com/android/tools/build/gradle/1.3.1/gradle-1.3.1.pom'。 
>连接到https://jcenter.bintray.com拒绝
  

问题很明显，我坐在后面企业代理可以阻止任何类似HTTPS连接的错误。
所以我的问题是：如何强制gradle使用HTTP来加载这些文件？这些属性应放在哪里（gradle文件，即gradle.properties中的哪一个）？

我已经在gradle属性文件中设置了这些：

  systemProp.http.proxyHost = myHost 
 systemProp.http.proxyPort = myPort 
 systemProp.http.proxyUser = myUser 
 systemProp.http.proxyPassword = myPassword 
  

任何链接，建议等都会有很大的帮助。

解决方案

我遇到同样的问题并修复了它。

gradle被迫通过https代理从jcenter获得依赖关系。

如果添加

  maven {urlhttp://jcenter.bintray.com} 
  

，而不是 jcenter（），gradle将此存储库视为一个带有http代理的简单Maven存储库。

您的项目 build.gradle 应如下所示：

<$ p $
仓库{
仓库{
maven {urlhttp://jcenter.bintray.com}
}
依赖关系{
classpath'com.android.tools.build:gradle:1.3.1'
}
}

allprojects {
repositories {
maven {url http://jcenter.bintray.com}
}
}

I am trying to build react-native android app, as a dependecy I see I have gradle, but it fails to load on build.Error message:

* What went wrong:
A problem occurred configuring root project 'MobileApp'.
> Could not resolve all dependencies for configuration ':classpath'.
   > Could not resolve com.android.tools.build:gradle:1.3.1.
     Required by:
         :MobileApp:unspecified
      > Could not resolve com.android.tools.build:gradle:1.3.1.
         > Could not get resource 'https://jcenter.bintray.com/com/android/tools/build/gradle/1.3.1/gradle-1.3.1.pom'.
            > Could not GET 'https://jcenter.bintray.com/com/android/tools/build/gradle/1.3.1/gradle-1.3.1.pom'.
               > Connection to https://jcenter.bintray.com refused

The issue is clear, I am sitting behind corporate proxy that blocks any HTTPSconnections like these in error.So my questions are: how to force gradle to use HTTP in loading these files? Where these properties should be put(which of gradle files, i.e. gradle.properties)?

P.S. I already have set these in gradle properties file:

systemProp.http.proxyHost= myHost
systemProp.http.proxyPort= myPort
systemProp.http.proxyUser= myUser
systemProp.http.proxyPassword= myPassword

Any links, suggestions or etc. will help a lot.

解决方案

I had same problem and fixed it.

gradle is forced to get dependencies from jcenter through https proxy.

if you add

maven { url "http://jcenter.bintray.com" }

in your repositories instead of jcenter(), gradle sees this repository as a simple maven repository with http proxy.

your project build.gradle should be like below:

buildscript {
    repositories {
        maven { url "http://jcenter.bintray.com" }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.1'
    }
}

allprojects {
    repositories {
        maven { url "http://jcenter.bintray.com" }
    }
}
