Overview

A repository is used to hold build artifacts and dependencies of varying types. There are only two types of repositories: local and remote.

A local repository is a cache of the remote downloads and also contains temporary build artifacts.

A remote repository is accessed over a network protocol such as http:// or even file://. They may be set up by other organizations, or by your own organization in order to share artifacts between different development teams.

Where are Repositories Declared?

The right place to declare additional repositories is, according to the Maven orthodoxy, the settings.xml file. Repositories can also be declared in pom.xml, but usually that type of information does not belong in there.

Adding a Remote Repository

Both "http://" and "file://" work.

A generic http repository:

...
<repositories>
    <repository>
        <id>my-internal-site</id>
        <url>http://myserver/repo</url>
    </repository>
</repositories>
...

This is an example of adding a local EAP repository:

...
<repositories>
    <repository>
        <id>jboss-datagrid-6.6.0-maven-repository</id>
        <url>file:///Users/ovidiu/runtime/jboss-datagrid-6.6.0-maven-repository</url>
    </repository>
</repositories>
...

Using Maven Repositories when Compiling JBoss EAP

Note that in some cases, multiple maven repositories are required, as with JDG 7 which relies on EAP 7:

...
<profiles>
    <profile>
        <id>jdg7</id>
        <repositories>
            <repository>
                <id>jboss-eap-7.0.0.GA-maven</id>
                <url>file:///Users/ovidiu/runtime/jboss-eap-7.0.0.GA-maven-repository/maven-repository</url>
            </repository>
            <repository>
                <id>jboss-datagrid-7.0-maven</id>
                <url>file:///Users/ovidiu/runtime/jboss-datagrid-7.0.0-maven-repository/maven-repository</url>
             </repository>
        </repositories>
        ...
    </profile>
</profiles>
...
