For the configuration editor (on http://wcm.io/caconfig/editor/usage.html) the maven coordinates listed on search.maven.org are
but by default this references a .jar file. But in the given directory I only find an AEM content package (type "zip"). Please adjust the link so other users don't have to figure that out themselves
the maven search syntax pointing to a specific non-jar artifact is misleading indeed.
as a first step i've used a different syntax to access maven search where the search result at least includes a ZIP package link.
