The url in the pom (of the submodules) is invalid

Maven seems to append the module name to project's url thus it references a page that does not exist.

http://bytebuddy.net/byte-buddy http://bytebuddy.net/byte-buddy-agent

Please set the correct url for the submodules as well or configure a server side redirect.

You can test this with mvn site and then checking the links on the dependency page.
