Proxy 安装logstash core event java（5.1.2）时出错

我正在通过代理在Windows Server 2012上安装Logstash。我已经设置了HTTP和HTTPS代理。我两个都试过了：

set HTTP_PROXY "<myhost:port>"
set HTTPS_PROXY "<myhost:port>"

但是，我收到以下错误：

C:\ELK_Stack\logstash\bin>logstash-plugin install logstash-input-beats
Validating logstash-input-beats
Installing logstash-input-beats
Error Bundler::InstallError, retrying 1/10
An error occurred while installing logstash-core-event-java (5.1.2), and Bundler cannot continue.
Make sure that `gem install logstash-core-event-java -v '5.1.2'` succeeds before bundling.
Error Bundler::InstallError, retrying 2/10
An error occurred while installing logstash-core-event-java (5.1.2), and Bundler cannot continue.
Make sure that `gem install logstash-core-event-java -v '5.1.2'` succeeds before bundling.

这可能会有帮助，因为这个问题似乎很理想！我试图将代理配置添加到ruby maven libs设置文件中，

/usr/share/logstash/vendor/bundle/jruby/1.9/gems/ruby-maven-libs-3.9/maven-home/conf/settings.xml

，但我得到了相同的错误。

C:\ELK_Stack\logstash\bin>logstash-plugin install logstash-input-beats
