camel-restlet has dependencies on a few org.restlet Maven artifacts:

org.restlet.jee:org.restlet:jar:2.3.12:compile
org.restlet.jee:org.restlet.ext.httpclient:jar:2.3.12:compile

These however are not found in our public Maven repositories nor in Maven central repository.

https://maven.repository.redhat.com/ga/org/restlet/jee/org.restlet/
https://maven.repository.redhat.com/earlyaccess/all/org/restlet/jee/org.restlet/
https://repo1.maven.org/maven2/org/restlet

I could only find them in repo http://maven.restlet.com/, which seems to be owned by Talend but we do not document to use this repository for Fuse 7 (and we probably don't want to use this repo)
