JDeodorant is an Eclipse plug-in that detects design problems in Java software, known as code smells, and recommends appropriate refactorings to resolve them.

For the moment, the tool supports five code smells, namely Feature Envy, Type/State Checking, Long Method, God Class and Duplicated Code.

JDeodorant is the outcome of research conducted in the Software Refactoring Lab at the Department of Computer Science and Software Engineering, Concordia University, Canada and the Software Engineering Group at the Department of Applied Informatics, University of Macedonia, Thessaloniki, Greece.

JDeodorant can be easily installed in your Eclipse IDE using the Eclipse Marketplace Client.
