How to use BOM file with Maven?

by

A bom is a so called bill of materials – it bundles several dependencies to assure that the versions will work together. JBoss has boms for many of it’s projects, including Arquillian and the JBoss AS itself.

There is an explanation of the bom usage in the maven docs – it is hidden well below.

A practical example:

You include the bom into your pom like this:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.jboss.bom</groupId>
            <artifactId>jboss-javaee-6.0-with-tools</artifactId>
            <version>${javaee6.with.tools.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

Then you do not have to specify the version attribute of a dependency, if it is defined in the bom like this:

<dependency>
    <groupId>javax.enterprise</groupId>
    <artifactId>cdi-api</artifactId>
    <scope>provided</scope>
</dependency>
