The static code analysis tools Code Formatter, Findbugs, PMD and Checkstyle are widely used in the Java development community. Each has an own purpose, strength and weaknesses.

This post explains about eclipse useful and important configuration and setting which required for every developer who used eclipse as primary IDE(Integrated Development Environment) for project development.


Configure Java Code Formatter

The analysis of Findbugs can be integrated into existing IDEs like the Eclipse IDE of IntelliJ.

The FindBugs Eclipse plugin allows FindBugs to be used within the Eclipse IDE. The FindBugs Eclipse plugin was generously contributed by Peter Friese. Phil Crosby and Andrey Loskutov contributed major improvements to the plugin.

To use the FindBugs Plugin for Eclipse, you need Eclipse 3.3 or later, and JRE/JDK 1.5 or later.
