All Implemented Interfaces:
  `Cloneable`

public class JDependTask extends Task
Runs JDepend tests.

JDepend is a tool to generate design quality metrics for each Java package. It has been initially created by Mike Clark. JDepend can be found at https://github.com/clarkware/jdepend. The current implementation spawn a new Java VM.
