Making an Ant task
Checkstyle can also be integrated with Ant task. Take the
following configuration sample for the Ant task and add it to
your build file. Generally, it is a good practice so that Java
files are checked at the build time for the coding standard. Any
deviation from the defined coding standard will stop the build
process.
<taskdef resource="checkstyletask.properties"
classpath="/path/to/checkstyle-all-3.1.jar"/> <checkstyle
config="config/mychecks.xml"> <fileset dir="src"
includes="**/*.java"/> <formatter type="plain"/>
<formatter type="xml" toFile="build/checkstyle_errors.xml"/>
</checkstyle>
Executing this ant task will produce the plain error report to
the console and generate an xml file to show the error reports.
The advantage of having an XML file is that you can apply
stylesheets to it, to generate HTML formatted output. Also, you
can migrate the error report to any other system.
Conclusion
Checkstyle is a valuable tool. I truly hope this article will
help you find some interest in incorporating Checkstyle in your
project. If you want more details, the Checkstyle website has a great
deal of information in it. Employing coding standards just got a little
easier
