We welcome all contributions to the project both big and small. From new features, bug reports to even spelling mistake corrections in the documentation. Please don’t hesitate to submit an issue.

The Contributing guide provides information on how to submit an issue or create a pull request to fix a bug or add a new feature to JBake.


The project has adopted the Semantic Versioning spec from v2.2.0 onwards to maintain an understandable backwards compatibility strategy.

The version format is as follows:

  • An increment of the major version represents incompatible API changes.

  • An increment of the minor version represents additional functionality in a backwards-compatible manner.

  • An increment of the patch version represents backwards-compatible bug fixes.

  • Existence of a label represents a pre-release or build metadata.

Docker Image

The image uses the official adoptopenjdk/openjdk11:alpine image for building a distribution of JBake and adoptopenjdk/openjdk11:alpine-jre for runtime.


To build the Docker image:

$ docker build -t jbake/jbake:latest .


To execute JBake via Docker run this from project directory:

$ docker run --rm -u jbake -v "$PWD":/mnt/site jbake/jbake:latest

This command will execute using the jbake user to avoid running as root and will mount the current working directory as /mnt/site in the Docker container where JBake is expecting your project files to be. By default the Docker image will execute a bake -b only.

If you want to bake and serve your project using the Docker image then you’ll need to override the default command:

$ docker run --rm -u jbake -v "$PWD":/mnt/site -p 8820:8820 jbake/jbake:latest -b -s

This command will also expose port 8820 from the container, you’ll also need to set the following option in your file:

Docker image timezone is UTC. This may affect the date and time expected in output content. To set different timezone, add TZ environment variable and set value to required timezone. Example - docker run --rm -u jbake -e TZ=America/New_York -v "$PWD":/mnt/site jbake/jbake:latest

Build System

The project uses Gradle 4.9+ as the build system. To build the JBake distribution ZIP file execute the following command from the root of the repo:

$ ./gradlew distZip

This will build a ZIP file in the /build/distributions folder.

For more information see Test, Build and Deploy

Coding conventions

The project uses a basic set of checkstyle rules to keep the Code in shape.

We configured the gradle checkstyle Plugin to run with the check task. It does not break the build if convention violations are found. But prints a warning and generates a report.

For more information see Test, Build and Deploy

Setup Intellij

  • Install checkstyle-idea plugin

    Settings → Plugins → CheckStyle-IDEA

  • Configure
