To integrate Crowd with your Maven 2 project, you will need to include the following dependency in your pom.xml:

<dependency>
	<groupId>com.atlassian.crowd</groupId>
	<artifactId>crowd-client-libraries</artifactId>
	<version>X.X</version>
        <type>pom</type>
</dependency>

Because the Crowd libraries are not published to the standard Maven repository, you will need to add Atlassian's public repository:

<repositories>
	<repository>
		<id>central</id>
		<url>https://m2proxy.atlassian.com/repository/public</url>
		<snapshots>
			<enabled>true</enabled>
			<updatePolicy>always</updatePolicy>
		</snapshots>
		<releases>
			<enabled>true</enabled>
		</releases>
	</repository>
</repositories>
