- 1024×768 minimum screen resolution
Java Development Kit (JDK): While IntelliJ IDEA includes a bundled JRE, having a JDK installed can be beneficial for certain projects.
Internet Connection: Required for downloading the IntelliJ IDEA installation files.

Pre-Installation Steps

To ensure a smooth installation, follow these pre-installation steps:

Update System Packages

Start by updating your system’s package list and upgrading installed packages. Open your terminal and run the following commands:

sudo apt update
sudo apt upgrade

This ensures you have the latest versions of all software, reducing the likelihood of compatibility issues.

Install Required Dependencies

IntelliJ IDEA requires certain dependencies to run correctly. Install these dependencies using the following command:

sudo apt install openjdk-17-jdk

This command installs the OpenJDK 17, a recommended Java Development Kit for IntelliJ IDEA.

Verify System Architecture

Confirm your system architecture is 64-bit, as IntelliJ IDEA requires a 64-bit environment. Run the following command:

uname -m

If the output is x86_64, your system is 64-bit. If not, you may need to use an older version of IntelliJ IDEA or upgrade your system.

Download IntelliJ IDEA

The next step is to download the IntelliJ IDEA installation files. You can download either the Community or Ultimate edition from the JetBrains website.

Obtaining the IntelliJ IDEA Installer

Visit the JetBrains IntelliJ IDEA Download Page.
Choose the edition you want to install (Community or Ultimate).
Select the “Linux” option to download the appropriate installation package (a .tar.gz file).

Verifying Download Integrity

After downloading the file, it’s crucial to verify its integrity to ensure it wasn’t corrupted during the download process. JetBrains provides SHA256 checksums for each release.

Understanding SHA256 Checksums

A SHA256 checksum is a unique identifier for a file. By comparing the checksum of your downloaded file with the one provided by JetBrains, you can confirm the file is intact.

Steps to Verify the Checksum

Open your terminal and navigate to the directory where you downloaded the .tar.gz file.
Run the following command, replacing <filename>.tar.gz with the actual filename:

sha256sum <filename>.tar.gz

Compare the output with the SHA256 checksum provided on the JetBrains website. If they match, your download is valid.

Handling Download Permissions

Ensure you have the necessary permissions to execute the downloaded file. By default, files downloaded from the internet may not have execute permissions. To add these permissions, use the following command:

chmod +x <filename>.tar.gz

Replace <filename>.tar.gz with the actual filename. This command adds execute permissions to the file, allowing you to proceed with the installation.

Installation Process

With the prerequisites met and the installation file verified, you can now proceed with the installation.

Running the Installer Script

Extract the .tar.gz file to your desired installation directory. A common location is /opt/. Use the following command:

sudo tar -xzf <filename>.tar.gz -C /opt/

Replace <filename>.tar.gz with the actual filename.

Navigate to the extracted directory:

cd /opt/intellij-idea-community-*/bin/

Adjust the directory name based on the version you downloaded.

Run the idea.sh script to start the installation:

./idea.sh

License Agreement Navigation

The first screen you’ll see is the license agreement. Read through it carefully, and if you agree, accept the terms to continue.

Installation Path Configuration

You’ll be prompted to configure the installation path. The default location is usually sufficient, but you can choose a different directory if needed.

Environment Initialization Options

The installer provides several options for initializing the environment:

Create Desktop Entry: Adds a shortcut to your desktop for easy access.
Create Associations: Associates file types (e.g., .java, .kt) with IntelliJ IDEA.
Update PATH: Adds IntelliJ IDEA’s bin directory to your system’s PATH environment variable, allowing you to run IntelliJ IDEA from the command line.

Select the options that best suit your needs and click “Next” to proceed.

Shell Profile Configuration

If you chose to update the PATH, the installer will prompt you to configure your shell profile. Follow the instructions provided to update your .bashrc or .zshrc file.

Verification of Installation Success

Once the installation is complete, IntelliJ IDEA will launch. You should see the welcome screen, where you can create a new project, open an existing one, or customize your settings.

Post-Installation Configuration

After the installation, there are a few additional steps you can take to optimize your experience.

Initializing IntelliJ IDEA

On the first launch, IntelliJ IDEA will guide you through the initial setup. You can customize the UI theme, keymap, and install additional plugins.

Setting Up Shell Integration

If you didn’t update the PATH during installation, you can manually add IntelliJ IDEA’s bin directory to your shell profile. Open your .bashrc or .zshrc file and add the following line:

export PATH="/opt/intellij-idea-community-*/bin:$PATH"

Replace /opt/intellij-idea-community-*/bin with the actual path to the bin directory.

Configuring Default Environments

You can configure default environments for your projects. Go to File > Settings > Build, Execution, Deployment > Build Tools > Maven (or Gradle) and configure the settings according to your project requirements.

Environment Variables Setup

Ensure that necessary environment variables such as JAVA_HOME are correctly set. This is crucial for projects that rely on specific Java versions.

Managing IntelliJ IDEA Environments

IntelliJ IDEA allows you to manage multiple environments for different projects, ensuring that each project has the dependencies it needs without conflicts.

Creating New Environments

To create a new environment, follow these steps:

Open IntelliJ IDEA and go to File > New > Project.
Select the project type and click “Next”.
In the project settings, you can configure the project SDK. Choose an existing SDK or create a new one.

Activating and Deactivating Environments

IntelliJ IDEA automatically activates the environment associated with the current project. You can switch between environments by opening different projects.

Installing Packages

You can install packages using IntelliJ IDEA’s built-in package manager. For Maven projects, you can edit the pom.xml file. For Gradle projects, you can edit the build.gradle file.

Environment Management Best Practices

Isolate Projects: Use separate environments for each project to avoid dependency conflicts.
Version Control: Keep your environment configurations in version control to ensure reproducibility.
Documentation: Document your environment setup to help others (and yourself) understand the project’s dependencies.

Troubleshooting Common Issues

Even with careful preparation, you may encounter issues during the installation or configuration process. Here are some common problems and their solutions:

Path Conflicts

If IntelliJ IDEA fails to start or throws errors related to missing commands, there may be a conflict in your PATH environment variable. Ensure that the IntelliJ IDEA bin directory is correctly added and that there are no conflicting entries.

Permission Problems

If you encounter permission errors, ensure that you have the necessary permissions to read and execute the IntelliJ IDEA files. Use the chmod command to adjust permissions as needed.

Shell Integration Issues

If shell integration is not working correctly, double-check your shell profile configuration. Ensure that the PATH variable is correctly set and that you have sourced your shell profile after making changes.

Package Installation Errors

If you encounter errors while installing packages, check your internet connection and ensure that the package repositories are accessible. You may also need to update your package manager’s configuration.

Advanced Configuration

For advanced users, IntelliJ IDEA offers a range of configuration options to customize the development environment.
