Maven: Failed to retrieve plugin descriptor error

Question

I configured Maven 3.0.3 and tried to download a sample project using archetypes with this command:

mvn archetype:generate -DarchetypeGroupId=org.graniteds.         


        

Answer 1

I had the same issue in Windows

and it worked since my proxy configuration in settings.xml file was changed

So locate and edit the file inside the \conf folder, for example : C:\Program Files\apache-maven-3.2.5\conf

<proxies>
    <!-- proxy
     | Specification for one proxy, to be used in connecting to the network.
     |
    <proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>
      <username>jorgesys</username>
      <password>supercalifragilisticoespialidoso</password>
      <host>proxyjorgesys</host>
      <port>8080</port>
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
    -->
  </proxies>

• In my case i had to chage from port 80 to 8080
• If you can´t edit this file that is located inside /program files you can make a copy, edit the file and replace the file located into /program files folder.
