Handle proxy setup for Jenkins-CLI

[de-jcup]

It would be nice if the proxy settings from eclipse would be used by Jenkins-CLI calls aswell.
So in a enterprise network servers inside cloud can be reached without problems.

-Dhttp.proxyHost=10.0.0.100 
-Dhttp.proxyPort=8800
-Dhttp.nonProxyHosts="localhost|127.0.0.1|10.*.*.*|*.foo.com‌​|etc"

But what about password settings etc.?

Hm... standard http proxy settings are not working correct.

Reason seems to be:
https://github.com/jenkinsci/jenkins/blob/master/cli/src/main/java/hudson/cli/CLIConnectionFactory.java
and
https://github.com/jenkinsci/jenkins/blob/master/cli/src/main/java/hudson/cli/CLI.java
...
It seems the CLIConnectionFactory is set bei CLI.java with command line parameter -p ?

-Djava.net.useSystemProxies=true must be set... than Jenkins CLI will use the given data!

[de-jcup]

Per default the eclipse proxy usage is not enabled, but can be done in Preferences (so behaviour as before is given).

Just another view for documentation
