Creating settings.xml in my local machine

Question

I am a new to Maven.Needs to find, how to set up settings.xml for Maven in my local machine and which remote repository should be available for it.

Answer 1

which remote repository should be available for it

In most cases you need not write anything in it, as Maven Central repository is available by default. Here are some common cases when it may be necessary to edit settings.xml:

1. You're working behind the proxy, so Maven should also be aware about this proxy:

   <proxy>
     <active>true</active>
     <protocol>http</protocol>
     <host>proxy.somewhere.com</host>
     <port>8080</port>
     <username>proxyuser</username>
     <password>somepassword</password>
     <nonProxyHosts>www.google.com|*.somewhere.com</nonProxyHosts>
   </proxy>
   

2. You need to plug in some addidional repositories to fetch the libraries missing in central one:

    <repositories>
       <repository>
         <id>codehausSnapshots</id>
         <name>Codehaus Snapshots</name>
         <releases>
           <enabled>false</enabled>
           <updatePolicy>always</updatePolicy>
           <checksumPolicy>warn</checksumPolicy>
         </releases>
         <snapshots>
           <enabled>true</enabled>
           <updatePolicy>never</updatePolicy>
           <checksumPolicy>fail</checksumPolicy>
         </snapshots>
         <url>http://snapshots.maven.codehaus.org/maven2</url>
         <layout>default</layout>
       </repository>
     </repositories>
     <pluginRepositories>
       ...
     </pluginRepositories>
   

3. You need to set some profiles as active by default

So, necessary settings depend solely on your needs.
