Welcome to JetBrains Runtime!
JetBrains Runtime is a fork of OpenJDK available for Windows, Mac OS X, and Linux. It supports enhanced class redefinition (DCEVM), features optional JCEF, a framework for embedding Chromium-based browsers, includes a number of improvements in font rendering, keyboards support, windowing/focus subsystems, HiDPI, accessibility, and performance, provides better desktop integration and bugfixes not yet present in OpenJDK.
NOTE: This is a development branch that is periodically synchronized with the OpenJDK master branch.
Release builds are based on these branches: * jbr11 (JDK 11) * jbr17 (JDK 17)
Download the latest releases of JetBrains Runtime to use with JetBrains IDEs. The full list can be found on the releases page.

Why Use JetBrains Runtime?
- Embedded browser: JetBrains Runtime includes the Java Chromium Embedded Framework (JCEF), which enables you to embed a Chromium-based browsers in your JVM-based application. To use it, download a build with JCEF.
- Enhanced class re-definition with the DCEVM technology that makes it easier to reload
changed code without restarting JVM; this feature needs to be explicitly enabled with
-XX:+AllowEnhancedClassRedefinition
. - Better FPS performance for graphics-intensive applications.
- Improved font rendering, keyboard input (such as shortcuts and multinational keyboards), HiDPI and accessibility support.
- Robust desktop experience: GUI-related fixes often reach JetBrains Runtime much earlier than the corresponding version of OpenJDK.

Getting Sources
macOS, Linux
git config --global core.autocrlf input
git clone git@github.com:JetBrains/JetBrainsRuntime.git
cd JetBrainsRuntime
git checkout jbr21
Windows
git config --global core.autocrlf false
git clone git@github.com:JetBrains/JetBrainsRuntime.git
cd JetBrainsRuntime
git checkout jbr21
Configuring the Build Environment
Here are quick per-platform instructions for those who can't wait to get started. Please refer to OpenJDK build docs for in-depth coverage of all the details.
TIP: To get a preliminary report of what's missing, run
./configure
and check its output. It would usually have meaningful advice on how to solve the problem.
Linux (Docker)
Create a container:
$ cd jb/project/docker
$ docker build .
...
Successfully built 942ea9900054
Run these commands in the new container:
$ docker run -v `pwd`../../../../:/JetBrainsRuntime -it 942ea9900054
# cd /JetBrainsRuntime
# sh ./configure
# make images CONF=linux-x86_64-normal-server-release
Ubuntu Linux
Install the necessary tools, libraries, and headers with:
$ sudo apt-get install autoconf make build-essential libx11-dev libxext-dev libxrender-dev libxtst-dev \
libxt-dev libxrandr-dev libcups2-dev libfontconfig1-dev libasound2-dev
Get Java 19 (for instance, Azul Zulu Builds of OpenJDK 19).
Then run the following:
$ cd JetBrainsRuntime
$ git checkout main
$ sh ./configure
$ make images
This will build the release configuration under ./build/linux-x86_64-server-release/
.
Windows
Install the following:
* Cygwin x64.
Required packages: autoconf
, binutils
, cpio
, diffutils
, file
, gawk
, gcc-core
, make
, m4
, unzip
, zip
.
Install those together with Cygwin.
* Visual Studio compiler toolset.
Install with the desktop development kit, which includes Windows SDK and compilers.
Visual Studio 2019 is supported by default.
* Java 19 (for instance, Azul Zulu Builds of OpenJDK 19).
If you have problems while configuring, read Java tips on Cygwin.
From the command line:
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64
"c:\Program_Files\cygwin64\bin\mintty.exe" /bin/bash -l
The first command sets up environment variables, the second starts a Cygwin shell with the proper environment.
In the Cygwin shell:
$ cd JetBrainsRuntime
$ git checkout main
$ bash configure --with-toolchain-version=2019
$ make images
This will build the release configuration under ./build/windows-x86_64-server-release/
.
macOS
Install the following:
* Xcode command line developer tools and autoconf
via Homebrew.
* Java 19 (for instance, Azul Zulu Builds of OpenJDK 19).
From the command line:
$ cd JetBrainsRuntime
$ git checkout main
$ sh ./configure
$ make images
This will build the release configuration under ./build/macosx-x86_64-server-release/
.
Developing
You can use CLion to develop native parts of the JetBrains Runtime and IntelliJ IDEA for the parts written in Java. Both require projects to be created.
CLion
Run
$ make compile-commands
in the git root and open the resulting build/.../compile_commands.json
file as a project.
Then use Tools | Compilation Database | Change Project Root
to point to git root of this repository.
See also this detailed step-by-step tutorial for all platforms: How to develop OpenJDK with CLion.
IDEA
Run
$ sh ./bin/idea.sh
in the git root to generate project files (add --help
for options). If you have multiple
configurations (for example, release
and fastdebug
), supply the --conf <conf_name>
argument.
Then open the git root directory as a project in IDEA.
