A plug-in for JetBrains' IntelliJ IDEA 15/2016/2017 which provides real-time feedback against a given CheckStyle profile by way of an inspection.
Released under a BSD-style licence - please see the LICENCE file for details.
OS X users of IDEA 15 please note - CheckStyle 6.2 and above require Java 8. As the default IDEA package for OS X runs on Java 6, please make use of the versions with the bundled JDK, e.g.
or, for Brew Cask users,
- brew cask install intellij-idea-ce-bundled-jdk
- brew cask install intellij-idea-bundled-jdk
All other users please note - we require IDEA to be running on JDK 8. AFAIK this is the default as of IDEA 2016.1.
Once installed, a new inspection will be available in the group 'CheckStyle'. The 'Inspections' item in the preferences panel will allow you to turn this on and to configure it.
Project exceptions are treated a little oddly. Because CheckStyle demands these to be on the current classpath, errors will appear if these have not as yet been compiled. Further, because we cache the real-time checkers for performance reasons, real-time scans may continue to show the errors after a compilation. A static scan will force a reload of the Checker and should resolve this.
Configuration is available under the Settings dialogue. This controls configuration for both the inspection and static scanning.
The main configuration option is that of the CheckStyle file. Multiple CheckStyle file may be added, and swapped between by using the checkbox. Files may be added using the 'Add' button.
The Scan Test Classes checkbox will enable scanning of Java files under test source roots. If disabled, these files will be ignored.
If a custom file is being used and properties are available for definition then these will accessible using the 'Edit Properties' button.
Eclipse-CS Variable Support
The following variables will be available if you have not otherwise overridden their values:
- basedir - mapped to the location of the current module file, or the project directory as a fallback.
- project_loc, workspace_loc - mapped to the project directory.
- config_loc, samedir - mapped to the directory the rules file is in, or the project directory for remote rules files (e.g. HTTP).
Third Party Checks
This tab allows you to specify any third-party checks which your configuration file makes use of. All selected directories/JAR files will be added to CheckStyle's classpath.
Copy libraries from project directory
The option "Copy libraries from project directory" will tell Checkstyle-IDEA to do the following when creating custom classloaders:
- scan a module's classpath and select those library entries which reside somewhere below the project directory
- copy those libraries to a separate temporary directory (normally under
.idea, if there is no
.ideadirectory, the system temp directory is used)
The internal classloaders will then use those copied libraries, thus preventing them from getting locked in the file system. Since this is mainly a problem on Windows, this feature is activated by default on Windows. If you know that all your libraries reside outside of the project (as is often the case when build tools such as Maven or Gradle are used), then you can disable this feature. Since it slows down checker creation, you might want to keep it disabled until necessary. After changing this option, it may be necessary to restart IDEA to see the effects.
If an error occurs during the check an exception will be thrown, which IDEA will then catch and display in the standard exceptions dialogue. If you're unsure as to why things are awry this would be your best bet - chances are it's a missing property or classpath pre-requisite.
sevntu.checkstyle offers a number of useful checks written by students of the Sevastopol National Technical University (SevNTU). They're also kind enough to offer instructions on setting them up with this plugin.
Checkstyle Addons offers additional Checkstyle checks not found in other Checkstyle extensions, and it's easy to set up in Checkstyle-IDEA.
Note that the plugin has been entirely developed on OS X - while it should be fine on Linux, I've no idea what result you'd get with Windows. YMMV.
The pre-requisites for the plugin are fairly light - you'll need Git and JDK 1.8.x. Make sure your
JAVA_HOME environment variable is set correctly before invoking Gradle.
git clone https://github.com/jshiell/checkstyle-idea.git checkstyle-idea cd checkstyle-idea
You can then easily build via Gradle:
./gradlew clean build
To run it in a sandboxed IDEA, run:
To debug the plugin, import the plugin into IDEA as a Gradle project, and then use the
runIdea Gradle target in debug mode.
Frequently Asked Questions
I see a Cannot Load Project error stating Unsupported major.minor version 52.0.
The plugin is compiled using language level 1.8, and hence must be run on Java 8. This is because CheckStyle 6.2 and above require at least JVM 1.7, and because I like lambdas.
If you're on OS X, use IDEA with the bundled JVM. Otherwise, please ensure IDEA is running using Java 8 or later. Jetbrains offer a support document on this subject.
I see 'Got an exception - java.lang.RuntimeException: Unable to get class information for . (0:0)'
CheckStyle is unable to retrieve information on exceptions in your project until you have built it. Build your project in IDEA and then rescan.
- If you import Gradle project withs Create separate module per source set active in IDEA 2016 or above then the module source paths are truncated. This means relative paths (e.g. suppressions on
src/test/.+) may not work as expected.
- The plugin will throw exceptions if used with class files targeted at a later version than that of the JDK used by IDEA. Please run IDEA on the latest available JVM, ideally the bundled version from JetBrains where available.
- If you change the configuration options the real-time scan will not be updated until the file is either changed or reopened.
- We do not check if a property definition is required for a given file. Hence you can exit configuration without setting required properties. Given, however, that CheckStyle files can change without the plug-in being aware this is something we'll always have to live with to some degree.
- CheckStyle errors and warnings from the inspection are both shown at a single level, as IDEA will only allow one warning level for an inspection.
Any comments or bug reports are most welcome - please visit the project website on GitHub.
This plug-in owes its existence to both the style-overlords at work mandating compliance with a CheckStyle configuration, and the Eclipse-CS authors for making me jealous of the real-time scan support available for Eclipse.

And also thanks are due to the authors and contributors of:
- Eclipse-CS, for inspiration and solutions to coding problems.
- JetStyle, for filling the area of static scanning and also giving me inspirations on coding solutions.
- CheckStyle, for without them we'd have merely void and chaos.
- JetBrains, for an IDE which is worth every penny and then some.
And a big thank-you to everyone who's sent me feedback or bug reports - both are much appreciated!
