gradle - Gradle从1.12升级到2.4后无法解决依赖关系

Question

在Win7上将gradle从1.12升级到2.4之后，在gradle项目中无法再解决依赖关系。
实际上，在同一终端(Windows中的bash终端)中，此操作成功完成:

$ /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'.

但这失败了:

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

Root project - MyProject

archives - Configuration for archive artifacts.

我已经尝试过了:
-将Maven从3.1.1升级到3.3.3
-更新了路径以访问新的gradle-2.4和maven-3.3.3
-重新打开Windows session
-杀死了gradle守护进程
-删除〜/ .gradle / caches
-删除〜/ .gradle并用相同的gradle.properties重新创建一个空的
-删除〜/ .m2 /存储库
-检查了本地cntlm代理配置(等级1.12可以很好地访问它)
-尝试使用参数“ -Dhttp_proxyHost=127.0.0.1 -Dhttp_proxyPort=3128 -Dhttps_proxyHost=127.0.0.1 -Dhttps_proxyPort=3129”

感谢您的任何建议。

在gradle 2.1中，他们从HTTP到HTTPS的switched mavenCentral()。也许您的代理在使用HTTPS时遇到了麻烦(或者gradle在使用HTTPS时在代理方面有了麻烦)。您可以使用以下代码切换回HTTP(永久或仅用于测试此假设)，该代码取自上述发行说明:

repositories {
    // note: this replaces mavenCentral()
    maven { url = 'http://repo1.maven.org/maven2/' }
}

并查看gradle用户指南中有关代理配置的“ Accessing the web via a proxy”。
