> The System.properties -Dhttp.nonProxyHosts=.... is not set during the Mojo executions,
but others parameters for http proxy are set ( useProxy, http.proxyHost, http.proxyPort),
resulting in inconsistencies .
> This is particulary annoying when using plugin cxf-maven-plugin and then another plugin
in the same jvm, like jetty:run or failsafe/surefire ... 
> The bugs occurs for example in mvn jetty:run after, doing a HttpURLConnection, with exception
like "407 Proxy authentication required" while trying to access a http resource within the
intranet, that should have by-passed the proxy but which is not due to missing -Dhttp.nonProxyHosts.
Notice that to reproduce the problem, you must have a very restrictive proxy with authentication
(like ntlm), and the bug occurs because credentials user/password are also not set passed
from maven to the jvm.
> The bug is in cxf-codegen-plugin/src/main/java/org/apache/cxf/maven_plugin/AbstractCodegenMoho.java
> line 332
> The following line is missing : 
>    System.setProperty("http.nonProxyHosts", String.valueOf(proxy.getNonProxyHosts()));
> Remarks:
> 1) to avoid side-effects on the current jvm, you could also restore previous value in
a try-finally :
>    String PROP = "http.nonProxyHosts"; // cf also http.proxyHost ..
>    String requiredPropValue = "localhost|*.mydomain";
>    String oldPropertyValue = System.getProperty(PROP);
>    if (!requiredPropValue.equals(oldPropertyValue)) {
>       // temporary change property
>       System.setProperty(PROP, requiredPropValue);
>    }
>    try {
>       // *** do work in cxf-plugin ***
>    } finally {
>       // restore old property value
>       if (!requiredPropValue.equals(oldPropertyValue)) {
>          System.setProperty(PROP, oldPropertyValue);
>       }
>    }  
>    
> 2) You should also use the credentials login/password in case of authenticating proxy...
