be able to propagate the proxy from settings.xml to plugins

attached plugin was generated from https://svn.apache.org/repos/asf/maven/plugins/trunk

it adds maven-proxy-plugin

Setting SystemVariable <java.net.useSystemProxies> to true works just fine for most environments. The proxy setting under setttings.xml should go away. At least it should move under profiles so that switching proxy is painless. Don't you feel the pain when you move from your work environment to home and suddenly you need to go and edit settings.xml for URL connections to work? . This works fine.

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.12.4</version>
<configuration>
<systemPropertyVariables>
<java.net.useSystemProxies>true</java.net.useSystemProxies>
</systemPropertyVariables>
</configuration>
</plugin>

Hmm, not sure it can be done for all plugin (got the need for dockbook and ant plugins)

Moreover i use a script to switch proxy in my conf file so the pain is just when it is not propagated in my builds

since it is a JVM switch setting -Djava.net.useSystemProxies=true to MAVEN_OPTS should make it work for all plugins (and anything else from within the code).

EDIT:
adding -Djava.net.useSystemProxies=true appended to MAVEN_OPTS did not work. However clean install -Djava.net.useSystemProxies=true works well with proxy on or proxy off. Surprised. I am sure I am missing something fundamental about the way MAVEN_OPTS is interpreted. Is it to set only the -X parameters?
