I just tried out a different approach which: - doesn't require any Maven plugin usage. - doesn't require to convert the Maven properties from the XML format to the Java properties file format etc. - is really simple.
So the idea is to simply bump one more level of parent-child dependency into our POM hierarchy (org.apache.camel:camel-dependencies:2.12-SNAPSHOT) which contains all the Maven properties of our 3rd party dependencies. And this is the diff for it dependencies.diff <http://camel.465427.n5.nabble.com/file/n5737472/dependencies.diff> . Then for the release notes of the upcomming 2.12.0 release we could just add the following link about our 3rd party dependencies, of course right now this resource doesn't exist on the central repo :-) http://search.maven.org/remotecontent?filepath=org/apache/camel/camel-dependencies/2.12.0/camel-dependencies-2.12.0.pom For example in case of our Camel Parent POM of the 2.11.1 release the link is: http://search.maven.org/remotecontent?filepath=org/apache/camel/camel-parent/2.11.1/camel-parent-2.11.1.pom Babak R.
