JBang IDE Support

VS Code / VSCodium

The JBang extension works in both Visual Studio Code and VSCodium (a free, open-source VS Code distribution). Running jbang edit installs VSCodium by default with Java and JBang extensions pre-configured — ready to code immediately.

Install

Quickest: just run jbang edit hello.java — JBang installs VSCodium and the required extensions automatically.

Manual install in VS Code: install JBang from the VS Marketplace.

Manual install in VSCodium: install JBang from Open VSX.

Features

  • Automatic classpath synchronization from JBang directives
  • Completion for //DEPS, //SOURCES, //FILES, and options
  • Run and Debug via CodeLens
  • Create scripts from templates, export native binaries, install as apps
  • Per-script projects with java.import.jbang.projectPerScript
  • Automatic annotation processor configuration
  • build.jbang and jbang-catalog.json support

# Install JupyterLab (requires Python)
pip install jupyterlab

# Install JBang kernel
jbang install-kernel@jupyter-java --java 25 --enable-preview jbang

Usage

Launch JupyterLab and create a new notebook with the JBang kernel:

jupyter lab

In JupyterLab, create a new notebook and select "JBang" as the kernel. You can now write and execute Java code with JBang directives like //DEPS directly in your notebooks!

Try Online

Want to try it without installing? Use our online Jupyter environment powered by MyBinder.
