maven nexus-staging-maven-plugin exception-connect timed out

不知道是国内的网络的问题还是别的原因，在deploy一个maven的artifact到oss server的时候总是报错：

[DEBUG] Connection manager is shutting down

反复尝试了多次还是报错，实在没有办法了，我只能通过代理上网然后手动进行发布，操作步骤如下：

1. 进入sonatype管理网站，https://oss.sonatype.org/#stagingRepositories ，前提是你记得注册他们的账号，具体如何操作，请google之。
2. 在左边的导航栏中点击 “Staging Upload”,进入如下页面：

3.  最重要的一步就是这里了，这里我们上传的所有的文件目录一定要是你使用maven 插件nexus-staging-maven-plugin 生成的staging目录，例如我的工程师becauseQA,那么目录就是： becauseQA-utils\target\nexus-staging\staging\104a5d5a8fd342\com\github\becauseQA

3.1 Upload Mode选择 “Artifact with a Pom”,点击“Select POM to Upload” 进入上面的staging目录选择对应的pom文件；

3.2 点击“Select Artifact(s) for Upload” 按钮还是进入刚才的staging目录，选择对应的jar文件点击“Add Artifacts”按钮，重复该步骤上传该目录下所有的jar文件包括doc和source文件，还有一些用gpg生成的asc文件，例如这里对应的所有需要上传的文件清单如下：

完成所有的设置后，点击“Upload Artifacts”按钮等待片刻上传即可成功。

实在是没有办法，国内的网络被blocked的太多了，只能尝试代理上网下手工方式进行发布了。

另附对应的nexus-staging-maven-plugin插件的配置信息
