Smell detection for eclipse
Arnab Bhattacharrya, Robert M. Fuhrer · 2004
Smells are architectural, rather than functional, flaws in software that tend to reduce maintainability, extensibility, modularity, testability, or other software quality measures. Common smells include overly-long method bodies, message chains, parallel inheritance, use of switch statements to implement polymorphic behavior, data clumps, overly specific variable types, and duplicated code. Code duplication in particular is a well-known source of maintenance problems. Because smells do not represent functional flaws, they can be remediated by behavior-preserving transformations (i.e. refactorings).
