Maven build issue - Connection to repository refused

Question

I wish to import, change, rebuild, test and push/check-in my changes to the code available in this Github repository

Currently, I do not wish to use any IDE or plug-ins for this purpose.

I installed Maven on my Windows machine and as proceeded as per the installation instructions as shown below :

Answer 1

Most probably you are behind proxy.

Try to do a telnet repo.maven.apache.org 80 and probably you will find it failed to connect.

In your settings.xml, add corresponding proxy settings to tell Maven to go through the proxy to download the artifacts

<settings>
    .......
    <proxies>
        <proxy>
            <active>true</active>
            <protocol>http</protocol>
            <host>your_proxy_host</host>
            <port>your_proxy_port</port>
            <!--
            <username>proxyuser</username>
            <password>somepassword</password>
            <nonProxyHosts>*.yourdomain.com|*.yourOtherDomain.com</nonProxyHosts>
            -->
        </proxy>
    </proxies>
</settings>
