Could not parse POM gradle

1、运行/opt/gradle-2.3/bin/gradle -Dhttp.proxyHost=xxxx -Dhttp.proxyPort=3128 -Dhttp.proxyUser=scmadmin -Dhttp.proxyPassword=xxx assemble

2、报错如下：

A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugCompile'.
   > Could not resolve xxxxx:1.2.0.
     Required by:
         workspace:app:unspecified
      > Could not parse POM http://xxxxx/nexus/content/groups/public/xxxx.pom
         > Already seen doctype.
      > Could not HEAD 'https://repo1.maven.org/maven2/xxxx.pom'.
         > Connection to https://repo1.maven.org refused
      > Could not HEAD 'https://jitpack.io/xxxx.pom'.
         > Connection to https://jitpack.io refused

3、查看对应依赖的pom文件，显示是114，原来代理把内网的地址跳转到114了，导致无法获取正确的pom文件。

4、解决方法，删除代理后解决。
