Gradle 从1.12升级到2.4后未解决依赖关系

在Win7上将gradle从1.12升级到2.4后，gradle项目中的依赖项将无法再解析。
实际上，在同一个终端（windows中的bash终端）中，这会成功：

$ /c/Program\ Files\ \(x86\)/gradle-1.12/bin/gradle dependencies
:dependencies

------------------------------------------------------------
Root project - MyProject
------------------------------------------------------------

archives - Configuration for archive artifacts.
No dependencies

compile - Compile classpath for source set 'main'.

鉴于此项规定失败：

$ /c/Program\ Files\ \(x86\)/gradle-2.4/bin/gradle dependencies
:dependencies

------------------------------------------------------------
Root project - MyProject
------------------------------------------------------------

archives - Configuration for archive artifacts.
No dependencies

我已经试过了：
-将maven从3.1.1升级到3.3.3
-更新了访问新gradle-2.4和maven-3.3.3的路径
-重新打开windows会话
-杀死了gradle守护进程
-已删除~/.gradle/缓存
-删除了~/.gradle，并用相同的gradle.properties重新创建了一个空的~/.gradle
-已删除~/.m2/存储库
-已检查本地cntlm代理配置（gradle-1.12可以很好地访问它）
-尝试使用参数“

-Dhttp\u proxyHost=127.0.0.1-Dhttp\u proxyPort=3128-Dhttps\u proxyHost=127.0.0.1-Dhttps\u proxyPort=3129

”

谢谢你的建议

在Gradle2.1中，它们从HTTP到HTTPS

mavenCentral（）

。也许您的代理在使用HTTPS时遇到了一些问题（或者gradle在使用HTTPS时在代理方面遇到了一些问题）。您可以使用以下代码切换回HTTP（永久或仅用于测试此假设），代码取自上述发行说明：

存储库{
//注意：这将替换mavenCentral（）
maven{url='1http://repo1.maven.org/maven2/' }
}

并查看gradle用户指南中有关代理配置的“”
