So, I have Hudson setup locally, and I am using an open source plugin that lets me create AWS Stacks from CloudFormation using the AWS SDK. However, the plugin fails because I am on a VPN, and I need to go through a proxy server. I have configured Hudson to use my proxy server for downloading (and updating) plugins. My question is - is there any way for my plugin to access Hudson's proxy settings and re-use those so that I don't have to enter the proxy settings in the plugin as well? I checked to see if Hudson happened to be setting the http.proxyHost, etc, System properties, and it doesn't appear that it is.
After downloading the Hudson code and looking at how it uses the proxy settings, I was able to utilize those in my plugin with the following lines:
Hudson hudson = Hudson.getInstance();
ProxyConfiguration proxyConfig = hudson != null ? hudson.proxy : null;
From there, I can call proxyConfig.name, proxyConfig.port, proxyConfig.getUserName(), and proxyConfig.getPassword() to get the settings that I needed.
