Why do you add the version property to each of your modules?

We use a parent pom like below, where all the information of a
dependency is added to the dependencyManagement tag:

<?xml version="1.0" encoding="UTF-8"?>
<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";>

        <modelVersion>4.0.0</modelVersion>
        <groupId>be.telenet</groupId>
        <artifactId>main</artifactId>
        <packaging>pom</packaging>
        <version>1.0-SNAPSHOT</version>
        <name>Main Project</name>

        <dependencyManagement>
        <dependencies>

                <dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                <version>${ver-junit}</version>
                <scope>test</scope>
                </dependency>

        </dependencies>
        </dependencyManagement>

        <properties>
                <ver-junit>3.8.1</ver-junit>
        </properties>
</project>

In the project POM's, I only use the groupId and artifactId of the
dependency. The rest is resolved via the information in the
dependencyManagement tag of the parent 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/xsd/maven-4.0.0.xsd";>

        <modelVersion>4.0.0</modelVersion>
        <groupId>be.telenet</groupId>
        <artifactId>someproject</artifactId>
        <packaging>jar</packaging>
        <version>1.0-SNAPSHOT</version>
        <name>someproject</name>

        <parent>
                <groupId>be.telenet</groupId>
                <artifactId>main</artifactId>
                <version>1.0-SNAPSHOT</version>
        </parent>

        <dependencies>
                <dependency>
                        <groupId>junit</groupId>
                        <artifactId>junit</artifactId>
                </dependency>
        </dependencies>
</project>

Works like a charm!
