See "How do I build more than one project at once?" here:
http://maven.apache.org/guides/getting-started/index.html

If you are using Eclipse, this can be useful:

If your parent project POM lists <modules>, then those projects will be
built when the parent is built.

I have a question in regards to this. Is there a way to build the projects as a whole, as you say? As of now, I have to run maven on each 


individual child, and I'm not sure if there is one way to call maven to



run the parent and all children at once.

Does anyone know if this is doable?

Hi Fredy,
The concept of parent poms can be applied to multi-module projects wherein it provides you the priviledge of building your modules individually or as a whole (project). 
You need to define your parent pom in your project's root directory

(ex.
C:\Project\pom.xml ) and the children pom in each module's root directory (ex. C:\Project\module-1\pom.xml). 

Please take a look below at the sample parent and child poms.

Parent POM:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>sample.project</groupId>
<artifactId>sample</artifactId>
<packaging>pom</packaging>
<name>Sample Project</name>
<version>1.0-SNAPSHOT</version>
<description>This is a sample project</description>
<modules>
  <module>module-1</module>
  <module>module-2</module>
  <module>module-3</module>
</modules>
<dependencies>
  <dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>3.8.1</version>
    <scope>test</scope>
  </dependency>
</dependencies>
<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>org.apache.maven</groupId>
      <artifactId>maven-model</artifactId>
      <version>2.0</version>
    </dependency>
  </dependencies>
</dependencyManagement>
</project>


Module-1 Child POM:
<project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
       xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/maven-v4_0_0.xsd";>
<parent>
  <groupId>sample.project</groupId>
  <artifactId>sample</artifactId>
  <version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>module-1</artifactId>
<name>Sample Project Module 1</name>
<dependencies>
  <dependency>
    <groupId>org.apache.maven</groupId>
    <artifactId>maven-model</artifactId>
  </dependency>
</dependencies>
</project>

Thanks,
Odea

hi,
i've read something about the parent pom at multiple places, but have

not found an explanation about it.



Is there a doc about parent pom's? Where to define it, how to extend

it?? Do it mean a pom in a multi module project like mojo-sandbox?
