FlexPMD tool helps us to improve code quality by auditing AS3/Flex source directory and detecting common bad practices code. like:

• Unused code (functions, variables, constants, etc.)
• Inefficient code (misuse of dynamic filters, heavy constructors, etc.)
• Over-complex code (nested loops, too many conditionals, etc.)
• Over-long code (classes, methods, etc.)
• Incorrect use of the Flex component lifecycle (commitProperties, etc.)

A report is generated by it which describing the violations of a given rule set.

Eclipse plugin are not available yet. FlexPMD can currently be invoked from:

• The command line
• Maven
• Ant

Adobe recently released (August 2009) the Flex implementation of PMD tool which extensively used at J2EE shops for code quality management.
