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:

- 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.
- Android Studio. The official IDE for Google's Android operating system.
- CLion. A cross-platform IDE for C and C++ from JetBrains.
- DataGrip. The IDE for Databases and SQL from JetBrains.
- GoLand. The cross-platform Go IDE from JetBrains.
- IntelliJ IDEA. The IDE for JVM from JetBrains.
- JProfiler. The Java profiler.
- PhpStorm. The PHP IDE from JetBrains.
- PyCharm. The Python IDE from JetBrains.
- Rider. The cross-platform .NET IDE from JetBrains.
- RubyMine. The Ruby and Rails IDE from JetBrains.
- Toolbox App. JetBrains IDE manager.
- WebStorm. The JavaScript IDE from JetBrains.
- YourKit. Java and .NET profilers.

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
./configureand check its output. It would usually have meaningful advice on how to solve the problem.
Create a container (use the mkdocker... variant for your architecture):
$ cd jb/project/docker
$ ./mkdocker_x86_64.sh
...
Successfully built 942ea9900054
Run these commands in the new container:
$ docker run -v `pwd`../../../../:/JetBrainsRuntime -it 942ea9900054
# cd /JetBrainsRuntime
# sh ./configure
# make images
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 libspeechd-dev libwayland-dev \
wayland-protocols libxkbcommon-x11-0
Get Java 23 (for instance, Azul Zulu Builds of OpenJDK 23).
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/.
- 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 21 (for instance, Azul Zulu Builds of OpenJDK 21). 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/.
If you want to add support of a11y announcing via NVDA screen reader, you will need to bundle the NVDA Controller Client library. You can do it with the following steps:
- Download the NVDA Controller Client library. You can find the link in its official README here
- Pass the path to the unpacked package to
configurevia an additional flag--with-nvdacontrollerclient=<path>. The build system will search the required library files under<path>/<target-arch>.
JBR is built with built-in support of JAWS screen reader.
If you want to disable it, run configure with the additional flag --disable-jaws-client.
Install the following:
- Xcode command line developer tools and
autoconfvia Homebrew. - Java 21 (for instance, Azul Zulu Builds of OpenJDK 21).
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/.
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.
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.
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.
