Open Source Java Source Code Analysis Tools

CODERU is a java code quality tool to enforce good structure in respect to packages and therefore modules dependencies. CODERU is an achronym and stands for Common Dependency Rules. The CODERU-rules rely on reserved package names and the allowed dependency rules between them expressed in a general way. Unlike other tools forcing you to define allowed or disallowed individual package dependencies CODERU is based on a fixed set of general rules. The dependencies between packages need not be defined explicitly. These general dependency rules are based on common design practices what is reflected in preserved package names: "api", "common", "impl" and "factory". As an integral part of CODERU there is a tool checking your code for rules conformance. See coderu rule description on http://coderu.org .

This tool helps you to reverse engineer UML Sequence Diagram for your java program at runtime. It works well with both complex java programs (that have multiple threads) and J2EE applications deployed on Application Servers.

PatternDetect is an Eclipse plugin that extracts the design patterns used in an Eclipse Java project. PatternDetect can be extended with new design patterns.

SIM stands for Struts In Mind, the goal is to transform a struts-config.xml file into a Freemind map, thus allowing a better vizualisation of the application mapping. Configuration is analyzed to provide a vision enhanced with colors and icons.

An Eclipse plug-in to monitor and act against the deterioration of software modularity in Java source code. On going development, with a prototype available.

"Component-Watch" is a tool discovering, showing and assessing the structure of (big) java programs from their classes. It finds what are the components composing a program, analyse what are the relations between those components and compare those the the permitted relations between components. The tool helps to easily define and display UML-like diagrams showing components and their relationship.
