Checkstyle

Checkstyle [1] is a static code analysis tool used in software development for checking if Java source code is compliant with specified coding rules. Originally developed by Oliver Burn back in , the project is maintained by a team of developers from around the world. The current stable release is version The programming style adopted by a software development project can help to ensure that the code is compliant with good programming practices which improve the quality, readability, and re-usability of the code and may reduce the cost of development. The checks performed by Checkstyle are mainly limited to the presentation of the code. These checks do not confirm the correctness or completeness of the code. Checkstyle rules are not programming style, they are merely rules for formatting the code. Checkstyle defines a set of available modules, each of which provides rules checking with a configurable level of strictness mandatory, optional Each rule can raise notifications, warnings, and errors. For example, Checkstyle can examine the following:.

The Checkstyle Plugin generates a report regarding the code style used by the developers. This version of the plugin uses Checkstyle 9. But you can upgrade the version used at runtime. The plugin can be configured in the project's POM. You can also use a custom ruleset by specifying it in the plugin configuration. Please note that the following parameters have been completely removed from the plugin configuration:. General instructions on how to use the Checkstyle Plugin can be found on the usage page.

A Checkstyle configuration specifies which modules to plug in and apply to Java source files. Modules are structured in a tree whose root is the Checker module. The next level of modules contains:. The TreeWalker operates by separately transforming each of the Java source files into an abstract syntax tree and then handing the result over to each of its submodules which in turn have a look at certain aspects of the tree. Checkstyle obtains a configuration from an XML document whose elements specify the configuration's hierarchy of modules and their properties. You provide a file that contains the configuration document when you invoke Checkstyle at the command line , and when you run a Checkstyle task in ant. A module element in the configuration XML document specifies a module identified by the element's name attribute.

Checkstyle

Checkstyle is a development tool to help programmers to write Java code that sticks to a coding standard. It automates the process of checking Java code. It is an open-source tool that checks code against a configurable set of rules. It allows you to define your own set of rules and check your code against it. The plugins are independent of each other and can be integrated individually in our build or IDEs. To Configure the Checkstyle in our Project, we need to add the plugins with the help of Maven Configuration. We can use a Sun-style check and a Google-style check two Predefined checks by Checkstyle. The config file will be checkstyle. The goal check mentioned in the execution section asks the plugin to run in the verify phase of the build and forces a build failure when a violation of coding standards occurs. After this, if we run the mvn clean install command then it will scan every file for violations and the build will fail if any violations deduct.
