These convenstions are not only limited to the Palladio core development but for all tools developed in the context of Palladio and behind. The Palladio project has defined coding conventions to ensure a common style of Java development. 1.2 Configuring Checkstyle for an Eclipse Project.1.1 Configuring Checkstyle in a new IDE.
You can make the Checkstyle plugin your own in the rule configuration editor. For example, is the Javadoc rule creating too many false positives? If so, an easy rule configuration change to make is to have Checkstyle ignore Javadoc. A developer can switch between files and also manage various Checkstyle rules via the tool's configuration page in the IDE's preferences window.
The Checkstyle for Eclipse plugin comes with two default configuration files: google_checks.xml and sun_checks.xml.

The plugin will also highlight lines of code that contain Checkstyle warnings in yellow to let the developer know exactly where the code problems lie. After you install the Checkstyle plugin for Eclipse, the IDE will restart, and two new views will be accessible from within your Java perspectives: the Checkstyle for Eclipse violations view and the Checkstyle for Eclipse violations chart. So, how do Eclipse users take advantage of the insights from Checkstyle's static analysis of Java code? The easiest way is to simply access the Marketplace link inside the IDE and search for the Checkstyle download. How does the Checkstyle plugin for Eclipse work? Checkstyle reports will flag any issues with your code.Ĭheckstyle can also be configured to use supplemental modules to perform tasks such as McCabe cyclomatic complexity calculations, but those aren't default features and need to be added by a developer. Most of its warnings are simply structural, such as "Line contains a tab character" or "Unused Imports," although some warnings are a bit more insightful, such as suggestions that code could be optimized by making certain variables final or that a given method has not been designed for future extension. View Checkstyle reportsĬheckstyle's static analysis of Java code stops short of bug identification and instead focuses on composition and form. Incorrect indentation levels, a lack of Javadoc comments, line lengths exceeding a predefined number of characters and instances where shadow variables occur are all flagged by Checkstyle's static analysis for Java routines. What does Checkstyle do?Ĭheckstyle's goal is to ensure that the Java code developer's write complies with accepted conventions and governance standards. The Checkstyle plugin for Eclipse will be the focus of this static analysis tutorial, but the concepts apply equally to other IDEs and build tools, such as Jenkins or Maven. There is a simple Maven Checkstyle plugin, and the Checkstyle plugins for Eclipse, NetBeans and IntelliJ enable it to easily integrate into all of the most popular Java IDEs. There are a number of great tools that perform static analysis of Java code, such as SonarQube, FindBugs, JaCoCo and PMD source code analyzer, but SourceForge's Checkstyle might be the simplest static code analysis tool to use when getting started.Ĭheckstyle produces easily understood results.
