Pass proxy configuration to the application in startup script

[tartakynov]

In *nix world, there is a widely accepted set of environment variables for proxy configuration:http_proxy, https_proxy, ftp_proxy, no_proxy. SBT already picks up those variables.

But in Java a quite different set of system properties is accepted as described in the following document http://docs.oracle.com/javase/7/docs/technotes/guides/net/proxies.html Many HTTP libraries support Java-style system properties out of the box, whereas *nix standard http_proxy stays neglected.

It would be very handy to have a setting bashScriptUseSystemProxy (it may be a different name) which would enable translation of http_proxy and no_proxy environment variables into following Java arguments upon startup: http.proxyHost, http.proxyPort, http.nonProxyHosts

Thanks for your feature request.

I'm not sure if native-packager is the right place to put this into.
Setting java options for a specific runtime behavior is not related to creating
packages.

Putting this in the Recipe section in the documentation would be okay, but the feature itself is out-of-scope for native-packager, I'm afraid.
