checkstyle ANT Task

Description

This task runs checkstyle over specified Java files. The task has been tested using ANT 1.3. The latest version of checkstyle can be found at http://www.puppycrawl.com/checkstyle. This task is included in the checkstyle distribution.

Installation

The easiest way is to include checkstyle-all-1.1.jar in the classpath. This contains all the classes required to run checkstyle. Alternatively, you must include the following in the classpath:

checkstyle-1.1.jar
ANTLR 2.7.1 classes. antlr.jar is included in the distribution.
Jakarta Regexp 1.2 classes. jakarta-regexp-1.2.jar is included in the distribution.

To use the task in a build file, you will need the following taskdef declaration:

  <taskdef name="checkstyle"
           classname="com.puppycrawl.tools.checkstyle.CheckStyleTask"/>
