When configuring EAP7 S2I image no_proxy settings for maven using proxy exclusion using an entire domain like this:

NO_PROXY=.example1.com,.example2.com

the assemble script in /usr/local/s2i/bin/assemble translate the configuration in settings.xml like this:

<proxy>
...
<nonProxyHosts>.example1.com|.example2.com</nonProxyHosts>
...
</proxy>

But the correct translation is:

<proxy>
...
<nonProxyHosts>*.example1.com|*.example2.com</nonProxyHosts>
...
</proxy>

With the * (star) in front of the domain name.

The error is at line 47 https://github.com/jboss-openshift/cct_module/blob/1.0/s2i-common/common.sh#L47

A fix might be:

noProxy="${noProxy//,/|}"
noProxy="${noProxy//|./|*.}"
noProxy="${noProxy/#./*.}"
