NOSQL for the Enterprise

The dependency:tree goal of the Maven plugin dependency supports various graphical outputs from the version 2.4 up. This is how you would create a diagram showing all dependencies in the com.example group in the dot format:

mvn dependency:tree -Dincludes=com.example-DappendOutput=true -DoutputType=dot -DappendOutput=true -DoutputFile=/path/to/output.dot

To actually produce an image from .dot you can use one of .dot renderers, f.ex. this online dot renderer (paste into the right text box, press enter).

You could also generate the output f.ex. in the graphml format & visualize it in Eclipse.

Thanks. Just a note, after trying this, it seems that maven 3.0.x is tied to version 2.1 by default, so you will need to specify 2.4 explicitly: 

mvn org.apache.maven.plugins:maven-dependency-plugin:2.4:tree -DoutputType=dot
Also note that the documentation for this plugin incorrectly states that the outputType property is available from 2.1 on. It should say 2.4.
