Building and Running the plugin

Use this to get started with developing the plugin.

Local Build

This plugin is built using Gradle. As this project includes the Gradle wrapper, developers don’t need to install Gradle. They need to install Java and make it available in the path or set environment variable JAVA_HOME the folder where they installed it. When building or running for the first time, the build-script downloads the community edition of IntelliJ automatically.

To build this plugin, run:

./gradlew -Dfile.encoding=UTF-8 buildPlugin

The ZIP file with plugin to distribute will be located in build/distributions.

The plugin.xml inside the archive will state version 0.0.1 unless the developer specifies an environment variable VERSION that holds a release number. This ensures that a locally built plugin will be overwritten by the JetBrains plugin update site.

Running the development version locally

To run the plugin for development, run

./gradlew -Dfile.encoding=UTF-8 runIde

To run all tests and the CheckStyle validations, run

./gradlew -Dfile.encoding=UTF-8 check

Running the plugin from with the IDE


You most likely want to do this for fast turnaround times when running single tests, and debugging both tests and the plugin itself. Please use IntelliJ IDEA as an IDE for developing on this plugin.

You can use the most recent version of the IDE. The build.gradle file specifies the minimum version for all users of the plugin, but when developing you are free to use a more recent version.

Setup Tasks

  1. Checkout the GitHub project and import it as a gradle project.

  2. Ensure to install the following plugins (your IDE should recommend installing them once you open the project):


    Helps with highlighting and code completion in Grammar files (*.flex).


    Helps to analyze the PSI (abstract syntax tree) created from the plugin in the IDE.


    This project contains a ready-to-go CheckStyle configuration that will work both in the IDE and in gradle.

  3. Go to Project Structure…​  Project Setting  Project.

  4. Choose “Amazon Corretto 11” as Project JDK
    (use Add JDK and Download JDK…​ if not already present).

Running Tests from the IDE

Running tests from the IDE might produce the error message “jarFiles is not set for PluginDescriptor”. To avoid this error message, set the following system properties when running tests from the IDE. When running tests from Gradle, this is added automatically:


Still, when running via the IDE, the tests in AsciiDocGrammarInspectionTest fail with an ExceptionInInitializerError when loading language tool classes. Please run these tests using the CLI command gradlew check as described above.

Validation Tasks

Perform these tasks to ensure that your setup is ready for development.

  1. Run the test cases from to see that running tests works in your setup.

  2. There are two ready-to-go run configurations checked in to git that you can run:


    building the plugin as a ZIP-file that you can then install locally into your IDE


    runs an IntelliJ community edition with the AsciiDoc plugin enabled. You can choose to run it in the debug mode.
