For example: <profile> <id>jboss-public-repository</id> <!-- Repository is active unless explicitly disabled e.g. -P!jboss-public-repository --> <activation> <property> <name>jboss-public-repository</name> <value>!false</value> </property> </activation> <repositories> <repository> <id>jboss-public-repository-group</id> <name>JBoss Public Maven Repository Group</name> <url>http://repository.jboss.org/nexus/content/groups/public</url> <layout>default</layout> <releases> <enabled>true</enabled> <updatePolicy>never</updatePolicy> </releases> <snapshots> <enabled>false</enabled> <updatePolicy>never</updatePolicy> </snapshots> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>jboss-public-repository-group</id> <name>JBoss Public Maven Repository Group</name> <url>http://repository.jboss.org/nexus/content/groups/public</url> <layout>default</layout> <releases> <enabled>true</enabled> <updatePolicy>never</updatePolicy> </releases> <snapshots> <enabled>true</enabled> <updatePolicy>never</updatePolicy> </snapshots> </pluginRepository> </pluginRepositories> </profile>
