I am trying to use jenkins slave behind the corporate proxy to fetch data from the internet. However when I run jobs in the slave, it is not able to connect to the internet. the slave environment has http_proxy, https_proxy and non proxy setup. If I login to the machine directly, I am able to run the curl/ping google and fetch data from the internet easily. but the same command if I run in the build step in a execute shell step, the connections times out, showing not able to connect to internet. I have setup proxy everywhere, including the java arguments and the issue doesn't seem to resolve. Any help to fix this issue is appreciated.
