I have install maven in my machine. I have properly set the class-path and maven home folder. Every time I execute mvn clean install, it gives me exception. I have also tried to delete the .m2 folder but the same result.

  • mvn -version output

Your debug output indicates that Clean is the first thing that it's trying to run, so I'm guessing it's failing to download any plugins from central.

First off, see if you can download the plugin jar directly in a web browser: http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-clean-plugin/2.5/maven-clean-plugin-2.5.jar

If that works then your web browser has connectivity to central but maven doesn't. That suggests to me that your web browser is using a proxy that maven isn't configured to use.

Maven proxy settings are described in depth here. To simplify that a little fill this out (replace the protocol/host/port with the values from your internet settings) and put it in the <settings> tag of your maven settings.xml file:

<proxies>
  <proxy>
    <id>proxy</id>
    <active>true</active>
    <protocol>http</protocol>
    <host>proxy.example.com</host>
    <port>8080</port>
  </proxy>
</proxies>
