How to install Intellij Idea Community on Feren OS

Introduction to IntelliJ IDEA Community Edition

IntelliJ IDEA Community Edition is a powerful, open-source Integrated Development Environment (IDE) primarily used for Java development but also supports other languages such as Kotlin, Groovy, and Scala. Known for its robust features, including advanced code editing, debugging, and project management capabilities, it offers an excellent platform for developers of all skill levels.

Feren OS, a user-friendly linux distribution based on Ubuntu, provides a seamless environment for developers looking to install and use IntelliJ IDEA. This guide will walk you through the installation process step-by-step, ensuring you have IntelliJ IDEA running smoothly on your Feren OS system.

Pre-Installation Steps

System Requirements

Before you begin the installation process, it’s essential to ensure that your system meets the necessary requirements to run IntelliJ IDEA Community Edition efficiently:

• Operating System: Feren OS or any Ubuntu-based distribution.
• RAM: Minimum of 2 GB (4 GB or more recommended).
• Disk Space: At least 1 GB for IDE, plus additional space for projects.
• Java Development Kit (JDK): A compatible version must be installed on the system.

Installing JDK

IntelliJ IDEA requires Java Development Kit (JDK) to function correctly. Feren OS does not come with JDK pre-installed, so let’s get that out of the way first.

1. Open Terminal: You can access the terminal by searching for “Terminal” in the applications menu.

2. Update Package Index: Always start by updating your package index to ensure you get the latest available versions. Type the following command:

   bash
   sudo apt update

3. Install JDK: You can install OpenJDK by running the command:

   bash
   sudo apt install openjdk-11-jdk

4. Verify Installation: After installation, check if JDK was installed correctly with this command:

   bash
   java -version

   You should see output indicating the version of Java that’s currently installed.

Installing IntelliJ IDEA

Now that you have JDK installed, it’s time to get IntelliJ IDEA Community Edition up and running.

Step 1: Downloading IntelliJ IDEA

1. Visit JetBrains Website: Navigate to the IntelliJ IDEA Community Edition download page.

2. Choose the Right Version: Select the “Community” version for free use.

3. Download the Tar.gz File: Click on the link to download the tar.gz archive. It will download to your default downloads folder.

Step 2: Extracting the Package

Once the download is complete, you need to extract the contents of the tar.gz file.

1. Navigate to Downloads Directory:

   bash
   cd ~/Downloads

2. Extract the File: Use the following command:

   bash
   tar -xzf ideaIC-*.tar.gz

   Replace ideaIC-* with the actual downloaded file name if necessary. This will create a directory named idea-IC-* in your Downloads folder.

Step 3: Moving IntelliJ IDEA to the Appropriate Directory

For better organization, it is advisable to move the IntelliJ IDEA directory to the /opt folder, which is generally used for optional software.

1. Move the Extracted Directory: Enter the following command:

   bash
   sudo mv idea-IC-* /opt/

Step 4: Starting IntelliJ IDEA

1. Navigate to IntelliJ IDEA’s bin Directory:

   bash
   cd /opt/idea-IC-*/bin

2. Launch IntelliJ IDEA: Start the application with:

   bash
   ./idea.sh

   The initial startup might take some time as it configures settings.

Step 5: Creating a Desktop Entry

To easily access IntelliJ IDEA from your applications menu, you can create a desktop entry.

1. Create a New Entry: Open a terminal and type:

   bash
   sudo nano /usr/share/applications/idea.desktop

2. Insert the Following Configuration:

   text
   [Desktop Entry]
   Version=1.0
   Type=Application
   Name=IntelliJ IDEA Community Edition
   Icon=/opt/idea-IC-/bin/idea.png
   Exec=/opt/idea-IC-/bin/idea.sh
   Comment=The Leading Java IDE
   Categories=Development;IDE;
   Terminal=false

   Save the file by pressing CTRL + O, and then exit nano by pressing CTRL + X.

3. Update Desktop Database: Finally, update the desktop database:

   bash
   sudo update-desktop-database

Now you should see IntelliJ IDEA listed among your installed applications, accessible directly from the application menu.

Step 6: Configuring the IDE

The first run of IntelliJ IDEA will prompt you to set up your development environment. Here are a few initial configuration steps to consider:

1. Select Themes and UI Options: You can choose between the default light theme or a dark one based on your preference.

2. Import Settings: If you’re migrating from a previous installation, it allows you to import settings from another IDE version.

3. Install Plugins: You can enhance your development experience with plugins that support various languages, frameworks, and tools.

Step 7: Updating IntelliJ IDEA

To keep IntelliJ IDEA up to date, you can check for updates from within the application:

1. Go to Help > Check for Updates.

2. Follow the prompts to download and install any available updates.
