Proxy Configuration in Eclipse Settings.xml

"Failure to transfer org.apache.maven.plugins:maven-failsafe-plugin:pom:2.16 from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will 
 not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-failsafe-
 plugin:pom:2.16 from/to central (http://repo.maven.apache.org/maven2): proxy.example.com"

I get the above error in the pom tag. I searched and found out about it due to a problem with proxy settings. But whatismyip.com shows "no proxies detected."

Question 1: Can I still be behind the proxy server? If so, how to get proxy information.

I found out that users> home> .m2> settings.xml should be updated by proxies. For example:

<proxies>
   <proxy>
      <id>example-proxy</id>
      <active>true</active>
      <protocol>http</protocol>
      <username>tomcat</username>
      <password>tomcat</password>
      <host>proxy.example.com</host>
      <port>8008</port>
      <nonProxyHosts>www.google.com|*.example.com</nonProxyHosts>
   </proxy>
</proxies>

Question 2: In this I replace my case in the tag or where I can find information specific to myself.

3: - > home > .m2 > settings.xml eclipse > > > > Active Provider (Manual ) > HTTP. .
