FeatureUtility can connect to Maven repository using proxy. However, users may not want to use proxy for some Maven repository even when they configured proxy settings. Common use case would be when they want connect to internal repository that doesn't require proxy.

Hi @jjiwooLim - this update is ready for review:

https://docs-draft-openlibertyio.mqj6zf7jocq.us-south.codeengine.appdomain.cloud/docs/latest/reference/command/featureUtility-commands.html

One thing I want to confirm is whether the 3 http envars at the end of the table should be all caps like the other ones. I thought environment variables were always specified in all caps but maybe this is an exception?

[jjiwooLim]

Hi, yes that's the usual way but we are following the convention used by featureUtility. It used the lowercase for proxy environment variables.

[jjiwooLim]

This is a list of patterns separated by | (bar) and , (comma) -> Period is not part of the separator. Only bar and comma.
