-- Introduction --

The eclipse-cs Checkstyle plug-in integrates the well-known source code analyzer Checkstyle into the Eclipse IDE.
Checkstyle is a Open Source development tool to help you ensure that your Java code adheres to a set of coding standards. Checkstyle does this by inspecting your Java source code and pointing out items that deviate from a defined set of coding rules.
Apart from using the Eclipse Checkstyle plug-in you can also use Checkstyle from the command line or as part of an Ant build.
For more information about using Checkstyle outside of Eclipse see the Checkstyle documentation.

With the Checkstyle Eclipse plug-in your code is constantly inspected for problems. Within the Eclipse workbench you are notified of problems via the Eclipse Problems View and source code annotations just as you would see with compiler errors or warnings.
