Install IntelliJ IDEA

IntelliJ IDEA is a cross-platform IDE that provides consistent experience on the Windows, macOS, and Linux operating systems.

IntelliJ IDEA is available in the following editions:

• Community Edition is free and open-source, licensed under Apache 2.0. It provides all the basic features for JVM and Android development.
• IntelliJ IDEA Ultimate is commercial, distributed with a 30-day trial period. It provides additional tools and features for web and enterprise development. For pricing information, see Subscription options & Pricing.

For more information about the editions, see the comparison matrix.

System requirements

Multi-core CPU. IntelliJ IDEA supports multithreading for different operations and processes making it faster the more CPU cores it can use.

SSD drive with at least 5 GB of free space

Officially released 64-bit versions of the following:

• Microsoft Windows 10 1809 or later Windows Server 2019 or later
• macOS 10.15 or later
• Any Linux distribution that supports Gnome, KDE , or Unity DE. IntelliJ IDEA is not available for the Linux distributions that do not include GLIBC 2.27 or later.

Pre-release versions are not supported.

Latest 64-bit version of Windows, macOS, or Linux (for example, Debian, Ubuntu, or RHEL)

You do not need to install Java to run IntelliJ IDEA because JetBrains Runtime is bundled with the IDE (based on JRE 17). However, to develop Java applications, a standalone JDK is required.

Older Linux distributions (before Ubuntu 18.04 and CentOS 8) don’t support the required JCEF version starting from IntelliJ IDEA version 2022.1. This means that components relying on the embedded browser will not work, for example, the Markdown HTML preview and the interactive debugger console.

Install using the Toolbox App

The JetBrains Toolbox App is the recommended tool to install JetBrains products. Use it to install and manage different products or several versions of the same product, including Early Access Program (EAP) and Nightly releases, update and roll back when necessary, and easily remove any tool. The Toolbox App maintains a list of all your projects to quickly open any project in the right IDE and version.

Install the Toolbox App

1. Download the installer .exe from the Toolbox App web page.
2. Run the installer and follow the wizard steps.
3. After you run the Toolbox App, click its icon in the notification area and select which product you want to install. To install a specific version, click and select Available versions .

Log in to your JetBrains Account from the Toolbox App, and it will automatically activate the available licenses for any IDE that you install.

Install the Toolbox App

1. Download the disk image .dmg from the Toolbox App web page. There are separate disk images for Intel and Apple Silicon processors.
2. Mount the image and drag the JetBrains Toolbox app to the Applications folder.
3. After you run the Toolbox App, click its icon in the main menu and select which product you want to install. To install a specific version, click and select Available versions .

Log in to your JetBrains Account from the Toolbox App, and it will automatically activate the available licenses for any IDE that you install.

Install the Toolbox App

1. Download the tarball .tar.gz from the Toolbox App web page.
2. Extract the tarball to a directory that supports file execution. For example, if the downloaded version is 1.17.7391, you can extract it to the recommended /opt directory using the following command:

Execute the jetbrains-toolbox binary from the extracted directory to run the Toolbox App. After you run the Toolbox App for the first time, it will automatically add the Toolbox App icon to the main menu.

Select the product that you want to install. To install a specific version, click and select Available versions .

Log in to your JetBrains Account from the Toolbox App, and it will automatically activate the available licenses for any IDE that you install.

If you installed IntelliJ IDEA via the Toolbox App, you can find the installation directory in the app: open the settings of the IDE instance in the Toolbox App, expand Configuration and look for the Install location field.

Standalone installation

Install IntelliJ IDEA manually to manage the location of every instance and all the configuration files. For example, if you have a policy that requires specific install locations.

1. Download the installer .exe . There is a separate installer for ARM64 processors.
2. Run the installer and follow the wizard steps. On the Installation Options step, you can configure the following:
   • Create a desktop shortcut for launching IntelliJ IDEA.
   • Add the directory with IntelliJ IDEA command-line launchers to the PATH environment variable to be able to run them from any working directory in the Command Prompt.
   • Add the Open Folder as Project action to the system context menu (when you right-click a folder).
   • Associate specific file extensions with IntelliJ IDEA to open them with a double-click.

To run IntelliJ IDEA, find it in the Windows Start menu or use the desktop shortcut. You can also run the launcher batch script or executable in the installation directory under bin .

To run IntelliJ IDEA, use the launcher batch script or executable in the extracted directory under bin .

1. Download the disk image . There are separate disk images for Intel and Apple Silicon processors.
2. Mount the image and drag the IntelliJ IDEA app to the Applications folder.

Run the IntelliJ IDEA app from the Applications directory, Launchpad, or Spotlight.

1. Download the tarball .tar.gz . There is a separate tarball for ARM64 processors.
2. Extract the tarball to a directory that supports file execution. For example, to extract it to the recommended /opt directory, run the following command for IntelliJ IDEA Ultimate:

Do not extract the tarball over an existing installation to avoid conflicts. Always extract it to a clean directory.

Execute the idea.sh script from the extracted directory to run IntelliJ IDEA.

To create a desktop entry, do one of the following:

• On the Welcome screen, click Configure | Create Desktop Entry
• From the main menu, click Tools | Create Desktop Entry

When you run IntelliJ IDEA for the first time, you can take several steps to complete the installation, customize your instance, and start working with the IDE.

For information about the location of the default IDE directories with user-specific files, see Directories used by the IDE.

Silent installation on Windows

Silent installation is performed without any user interface. It can be used by network administrators to install IntelliJ IDEA on a number of machines and avoid interrupting other users.

To perform silent install, run the installer with the following switches:

• /S : Enable silent install
• /CONFIG : Specify the path to the silent configuration file
• /D : Specify the path to the installation directory This parameter must be the last in the command line, and it should not contain any quotes even if the path contains blank spaces.

To check for issues during the installation process, add the /LOG switch with the log file path and name between the /S and /D parameters. The installer will generate the specified log file. For example:

ideaIU.exe /S /CONFIG=d:\temp\silent.config /LOG=d:\JetBrains\IDEA\install.log /D=d:\IDE\IntelliJ IDEA Ultimate

Silent configuration file

You can download the default silent configuration file for IntelliJ IDEA at https://download.jetbrains.com/idea/silent.config

The silent configuration file defines the options for installing IntelliJ IDEA. With the default options, silent installation is performed only for the current user: mode=user . If you want to install IntelliJ IDEA for all users, change the value of the installation mode option to mode=admin and run the installer as an administrator.

The default silent configuration file is unique for each JetBrains product. You can modify it to enable or disable various installation options as necessary.

It is possible to perform silent installation without the configuration file. In this case, omit the /CONFIG switch and run the installer as an administrator. Without the silent configuration file, the installer will ignore all additional options: it will not create desktop shortcuts, add associations, or update the PATH variable. However, it will still create a shortcut in the Start menu under JetBrains .

Install as a snap package on Linux

You can install IntelliJ IDEA as a self-contained snap package. Since snaps update automatically, your IntelliJ IDEA installation will always be up-to-date.

To use snaps, install and run the snapd service as described in the installation guide.

On Ubuntu 16.04 LTS and later, this service is pre-installed.

IntelliJ IDEA is distributed via two channels:

The stable channel includes only stable versions. To install the latest stable release of IntelliJ IDEA, run the following command:

Starting Intellij IDEA from icon on linux: No JDK found

I am using Linux Mint and trying to run Intellij IDEA from icon on the start menu. Starting Intellij via terminal ./idea.sh works fine. However launching from icon (points to the same ./idea.sh ) ends up with following error: No JDK found. Please validate either IDEA_JDK, JDK_HOME or JAVA_HOME environment variable points to valid JDK installation. Running echo $JAVA_HOME and java -version works correctly and shows installed JDK. How can I fix this issue and why starting from icon differs from starting from terminal?

Where are you setting JAVA_HOME ? I’m guessing it’s a file that only gets loaded by the shell in terminal windows, but not for your desktop session. That is, what is happening is: your desktop runs without JAVA_HOME set, you click on the icon, the launcher uses the environment on the desktop, breaks. You run a terminal, .bashrc sets JAVA_HOME, you run idea.sh in the terminal, then it works.

Actually, that’s not necessary, we’ve already established that the variable is not available in your login environment and thus to the launcher, so either way you need to make it available. It’s been a hot minute since I used a Linux, but can’t you set environment variables on the launcher shortcut directly? Change the call to idea.sh to be JAVA_HOME=/path/to/some/jdk /path/to/idea.sh ? Or set JAVA_HOME in .profile or whatever file Linux Mint loads at login.

@DmitryKach, I think what sdkman does is to expose the JAVA_HOME every time the terminal is launched. If this is the case you will have to manually export your java home (point to sdkman files, it’s OK)

Change the boot Java runtime of the IDE

As a Java application, IntelliJ IDEA requires a Java runtime environment (JRE). By default, IntelliJ IDEA uses JetBrains Runtime (a fork of OpenJDK), which is included with the IDE. JetBrains Runtime fixes various known OpenJDK and Oracle JDK bugs, and provides better performance and stability. However, in some cases you may be required to use another Java runtime or a specific version of JetBrains Runtime.

Changing the boot Java runtime may cause unexpected problems. Do not change it unless you were specifically asked to do so by JetBrains support.

The runtime for IntelliJ IDEA is not the same runtime used for your applications. Define an SDK for each of your projects, which includes the necessary development and runtime environment.

Switch the Java runtime used to run IntelliJ IDEA

1. From the main menu, select Help | Find Action or press Ctrl+Shift+A .
2. Find and select the Choose Boot Java Runtime for the IDE action.
3. Select the new desired runtime and click OK . If necessary, you can change the location where IntelliJ IDEA will download the selected runtime.
4. Wait for IntelliJ IDEA to restart with the new runtime.

When you open the Choose Boot Runtime for the IDE dialog for the first time, it may take a while to load the list of JetBrains Runtime builds from the server.

To use a different Java runtime available on your computer, select Add Custom Runtime… under Advanced in the New field. IntelliJ IDEA lists all the JDKs and JREs that it was able to detect. Select one or click Add JDK to specify the location of the desired Java home directory.

To reset back to the default runtime that the IDE initially used, click Use Default Runtime .

When using a non-default Java runtime for IntelliJ IDEA, it will not update with the IDE and may not be compatible with the new version. Reset back to the default runtime when updating IntelliJ IDEA to get the latest compatible version of JetBrains Runtime.

The path to the selected runtime is stored in the idea.jdk or idea64.jdk file in the IntelliJ IDEA configuration directory. If there are problems with the selected runtime, you can delete this file to revert to the default runtime.

You can also override the runtime used for IntelliJ IDEA by adding the IDEA_JDK environment variable with the path to the desired JDK home directory.
