The latest version distribution does not work! Maven can't find the artifact even if the entry is registered.
If you use a profile, make sure to add <type>pom</type> to the dependency.
You should use the official search site for Maven artifacts. You can find all TrueZIP 7.7.2 artifacts here: http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22de.schlichtherle.truezip%22%20AND%20v%3A%227.7.2%22
The link you have given is confusing to me. It does not give a complete <dependency> snippet and <repository> snippet in order to access to the latest TrueZip library in Maven.
Let me suggest to you to put these two elements on your website so that there is no confusion.
I still can't get access to your TrueZip from Maven.
The best way to get started is by using a Maven archetype to generate a sample project.
