When I am trying to upgrade jenkins automatically I am getting the following error:

hudson.util.IOException2: Failed to download from http://updates.jenkins-ci.org/download/war/2.11/jenkins.war (redirected to: http://ftp-nyc.osuosl.org/pub/jenkins/war/2.11/jenkins.war)

(....)

Caused by: java.net.SocketTimeoutException: Read timed out

-------

The proxy configuration is fine because I am able to update plugins. I belive I have timeout only when updting jenkins.war because of the size of the file.

I notice this error since Jenkins version 1.6

-------

Solution for the problem:

I need a way to configure this timeout
