在Eclipse 3.5中更改用户代理以进行新的软件安装

如何在Eclipse 3.5中更改用户代理？我尝试向eclipse.ini文件添加属性 -Dhttp.agent =我的用户代理，但使用WireShark我可以看到用户代理仍然是 Jakarta Commons-HttpClient / 3.1 。我需要更改这个，以便我可以通过公司的过滤器来下载插件和更新。这是我的eclipse.ini文件：

How can the user-agent be changed in Eclipse 3.5? I tried adding the property -Dhttp.agent=my user agent to the eclipse.ini file, but using WireShark I can see that the user agent is still Jakarta Commons-HttpClient/3.1. I need to change this so that I can get through the company's filter to download plug-ins and updates. Here is my eclipse.ini file:
