To build a Maven based project, open your console, change to your project folder where pom.xml file is placed, and issue this command :
mvn package
This will execute the Maven “package” phase.
Maven build lifecycle
Maven is run by phases, read this default Maven build lifecycle article for more detail. So, when the “package” phase is executed, all its above phases – “validate“, “compile” and “test“, including the current phase “package” will be executed orderly.

“mvn package” example
When you run “mvn package” command, it will compile source code, run unit test and pack it depends on your “packaging” tag in pom.xml file. For example,
1. If “packaging” = jar, it will package your project into a “jar” file and put it into your target folder
File : pom.xml
<project ...>
<modelVersion>4.0.0</modelVersion>
<groupId>com.mkyong</groupId>
<artifactId>Maven Example</artifactId>
<packaging>jar</packaging>
...
2. If “packaging” = war, it will package your project into a “war” file and put it into your target folder.
File : pom.xml
<project ...>
<modelVersion>4.0.0</modelVersion>
<groupId>com.mkyong</groupId>
<artifactId>Maven Example</artifactId>
<packaging>war</packaging>
...
I am getting this error-
Could not resolve archetype org.apache.maven.archetypes:maven-archetype-quickstart:1.1 from any of the configured repositories
Please help me resolve this issue.
Hi. My project team is using maven build. We have a package name as **/**/**/RCS under which all the classes are getting generated. But the jar does not contain these classes for some reason. Is there a way to include these classes into the RCS.jar?
There is no problem with other packages having a similar format.
Please suggest where the issue can be.
Thanks in advance!!!
