This Maven plugin generates dependency graphs on single modules or in an aggregated form on multi-module projects. The graphs are represented by .dot files. In case that Graphviz is installed on the machine where this plugin is run, the .dot file can be directly converted into all supported image files.

There is a newer version: 4.0.3
