How to install Intellij Community edition on Linux Lite 6.2

Introduction to IntelliJ Community Edition

IntelliJ IDEA is one of the most popular Integrated Development Environments (IDEs) used by developers worldwide, particularly for Java development. The Community Edition is free, open-source, and offers many features suitable for various programming tasks. For Linux Lite users, installing IntelliJ Community Edition can be straightforward with the right instructions. This guide will walk you through the installation process, ensuring you get up and running while also highlighting some tips and tricks to maximize your productivity.

Preparing Your System

Before you begin the installation process, it’s crucial to prepare your Linux Lite system to ensure compatibility and smooth functionality.

System Requirements

Make sure your system meets the following requirements:

• Operating System: Linux Lite 6.2 (or similar distributions)
• Memory: At least 2 GB RAM (4 GB recommended)
• Disk Space: A minimum of 5 GB free disk space
• Java Development Kit (JDK): IntelliJ requires a JDK. Ensure you have a compatible version installed.

Installing JDK

If you don’t have a JDK installed, you can easily set it up using the terminal. Open a terminal and execute the following commands:

bash
sudo apt update
sudo apt install openjdk-11-jdk

This will install OpenJDK 11, which is compatible with IntelliJ Community Edition. To verify the installation, use:

bash
java -version

Updating Your System

It’s always recommended to keep your system updated before installing any software. Run the following commands to ensure your system is up-to-date:

bash
sudo apt update && sudo apt upgrade -y

Downloading IntelliJ Community Edition

Now that your system is prepared, you can proceed to download IntelliJ Community Edition.

Step-by-Step Download Guide

1. Open your preferred web browser.
2. Navigate to the official JetBrains website: JetBrains IntelliJ IDEA.
3. Under the “Community” section, select the Linux option to start the download process.
4. The downloaded file will be a .tar.gz archive, which contains the IntelliJ IDEA installation files.

Installing IntelliJ Community Edition

Once the download is complete, you need to install IntelliJ IDEA.

Extracting the Archive

Navigate to your Downloads directory and extract the downloaded .tar.gz file. You can do this via the terminal:

bash
cd ~/Downloads
tar -xzf ideaIC-*.tar.gz

This command will create a new directory named “idea-IC-x.y.z” (where x.y.z represents the version number).

Moving IntelliJ to a Suitable Directory

It’s a good practice to move the extracted directory to the /opt folder, which is commonly used for third-party applications. You can do this with the following commands:

bash
sudo mv idea-IC-* /opt/idea-IC

Creating a Symlink for Easy Access

To simplify launching IntelliJ IDEA from the terminal, create a symbolic link:

bash
sudo ln -s /opt/idea-IC/bin/idea.sh /usr/local/bin/idea

Launching IntelliJ IDEA

You can now launch IntelliJ IDEA using the terminal:

bash
idea

Alternatively, you can also run the .sh script directly from the installation directory.

Setting Up IntelliJ Community Edition

When you first launch IntelliJ IDEA, you’ll go through an initial setup wizard. Here’s what you need to know:

Configuration Settings

1. Import Settings: If this is your first install, choose to start without importing settings.
2. UI Theme: Select your preferred theme. You can choose between light and dark themes based on your comfort.
3. Plugins: The wizard will suggest essential plugins. You can install some popular ones, such as Git support or Kotlin if needed.

Creating Your First Project

1. Click on “New Project.”
2. Choose the type of project you want to create – for example, a Java project.
3. Configure the project’s SDK if it’s not detected automatically.
4. Name your project and select the desired location.
5. Click “Finish” to set up your project.
