And error in result. How to configure plugin to work with proxy?

The problem of the proxy should be easy to solve. It is necessary to edit the configuration maven file(settings.xml) with your proxy configuration:


<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                  https://maven.apache.org/xsd/settings-1.0.0.xsd">
  ...
<proxies>
<proxy>
  <id>myproxy</id>
  <active>true</active>
  <protocol>http</protocol>
  <host>proxy.somewhere.com</host>
  <port>8080</port>
  <username>proxyuser</username>
  <password>somepassword</password>
  <nonProxyHosts>*.google.com|ibiblio.org</nonProxyHosts>
</proxy>
...

You can find further information about it on the
[maven webpage]
(https://maven.apache.org/settings.html) .

Have the same issue. My proxy is configured in settings.xml. No effect.
