		<name>Maven Central</name>
		<url>http://repo1.maven.org/maven2/</url>
	</repository>
	<repository>
		<id>spring-release</id>
		<name>Spring Maven Release Repository</name>
		<url>http://repo.springsource.org/libs-release</url>
	</repository>
	<repository>
		<id>atlassian-m2-repository</id>
		<url>https://m2proxy.atlassian.com/repository/public</url>
