Prerequisites

Before you begin the installation of Eclipse IDE on Rocky Linux 9, it is essential to ensure that your system meets the necessary prerequisites. This section outlines the system requirements and the software you need to have installed.

System Requirements

• Operating System: Rocky Linux 9 or compatible distributions.
• RAM: Minimum of 4 GB (8 GB recommended for optimal performance).
• Disk Space: At least 1 GB of free disk space for Eclipse installation.
• Processor: 64-bit processor is required.

Necessary Software

To run Eclipse IDE, you need to have the Java Development Kit (JDK) installed on your system. The recommended version is:

• JDK Version: JDK 11 or later.

Updating Your System

Before installing any software, it is a good practice to ensure that your system is up to date. You can update your system by running the following command in the terminal:

sudo dnf update

Method 1: Installing Eclipse IDE using the Eclipse Installer

This method involves using the official Eclipse Installer, which simplifies the installation process. Follow the steps below to install Eclipse IDE on your Rocky Linux 9 system.

Step 1: Downloading the Eclipse Installer

To begin, navigate to the official Eclipse download page:

https://www.eclipse.org/downloads/

Select the appropriate installer for Linux and download it to your system. Make sure to choose the version that matches your architecture (64-bit).

Step 2: Extracting the Installer

Once the download is complete, open your terminal and navigate to the directory where the installer was downloaded. Use the following command to extract the downloaded tarball:

tar -xzf eclipse-inst-linux64.tar.gz

This command will create a new directory containing the Eclipse Installer.

Step 3: Running the Installer

Navigate to the installer directory:

cd eclipse-installer

Now, execute the installer script with the following command:

./eclipse-inst

This will launch the Eclipse Installer GUI. Follow the prompts in this graphical interface.

Step 4: Selecting Packages

In the installer, you will see various Eclipse packages available for installation. Choose the package that best suits your development needs, such as:

• Java Developer
• C/C++ Developer
• PHP Developer
• PDE (Plugin Development Environment)

Step 5: Installation Process

After selecting the desired package, click on the Install button. The installer will download and install all necessary components. This process may take a few minutes depending on your internet speed. You may be prompted to accept license agreements during this process; make sure to read them carefully before proceeding.

Step 6: Verifying Installation

Once the installation is complete, you can verify that Eclipse is installed correctly by launching it from the terminal:

eclipse

If Eclipse opens successfully, congratulations! The installation was successful. If not, check for any error messages in your terminal that might indicate what went wrong.

Method 2: Installing Eclipse IDE using Snap

This method utilizes Snap, a package management system that makes it easy to install and manage software on Linux. Follow these steps to install Eclipse IDE using Snap on your Rocky Linux 9 system.

Step 1: Installing Snapd

You need to install Snapd first, which enables Snap packages. Open your terminal and run:

sudo dnf install snapd

This command installs Snapd on your system. After installation is complete, enable the Snapd socket with:

sudo systemctl enable --now snapd.socket

Step 2: Installing Eclipse via Snap

The next step is to install Eclipse using Snap. Run this command in your terminal:

sudo snap install --classic eclipse

This command will download and install the latest version of Eclipse IDE available through Snap.

Step 3: Launching Eclipse

You can launch Eclipse by running:

eclipse

You can also find it in your applications menu under “Eclipse”. Click on it to launch.

Advantages and Disadvantages of Using Snap

The use of Snap for installing Eclipse comes with its own set of advantages and disadvantages:

• Advantages:
  • Simplified installation and updates through a single command.
  • Eclipse runs in an isolated environment which reduces dependency issues.
• Disadvantages:
  • You might experience delays in receiving updates compared to direct installations from official sources.
  • The Snap packaging method may consume more disk space due to its bundled dependencies.

The next crucial step before fully utilizing Eclipse IDE is setting up a proper Java environment since it relies heavily on Java Development Kit (JDK). This section will guide you through installing JDK and configuring necessary environment variables.

You can choose between OpenJDK or Oracle JDK for your Rocky Linux 9 system. To install OpenJDK, run this command:

sudo dnf install java-11-openjdk-devel

If you prefer Oracle JDK, visit their official website to download it and follow their specific installation instructions provided there.

A vital part of configuring Java is setting up JAVA_HOME variable which helps other applications locate Java installations. Open your terminal and edit either .bashrc or .bash_profile file as follows:

nano ~/.bashrc

Add this line at the end of the file:

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk

This path may vary based on where JDK was installed; adjust accordingly if needed. Save changes and apply them by running:

source ~/.bashrc

You can verify if Java was installed correctly by running this command in your terminal:

java -version

If everything is set up properly, you’ll see version information displayed indicating that Java is functioning correctly.

Your final step after successfully installing Eclipse IDE is launching it so you can start developing applications. This section provides instructions on how to launch Eclipse and perform initial setup tasks.

You can launch Eclipse IDE in two ways:

• • The easiest way is from terminal; simply type:

eclipse

• You can also find it in your applications menu; just click on it to open.

The first time you launch Eclipse, you’ll be prompted to select a workspace—a directory where all your projects will reside. You can either accept its default location or choose another by clicking on Select Other….

Selecting a workspace allows better organization of projects according to personal preferences or project types. After making your selection, click on Lauch, and you’ll be greeted with a welcome screen showcasing various features available within Eclipse along with tutorials for beginners.

If you’ve followed all steps carefully but still encounter issues while using or launching eclipse here are some common problems along with their solutions :

Eclipse Won’t Start

If eclipse fails to start check if correct version of JDK has been installed . To confirm run:

java -version </ code ></ pre >
If version isn’t compatible reinstall appropriate version of JDK.

Error Messages During Launch

Sometimes users may face error messages while trying start eclipse . These could indicate missing libraries or incorrect configurations . Check logs located at:

~/.eclipse//workspace/.metadata/.log

This log file contains detailed information about errors encountered during startup.

No GUI Displayed </ h4 >

If GUI doesn’t appear after executing eclipse command ensure X11 forwarding enabled if working remotely over SSH . You can do this by adding -X flag when connecting :

ssh -X user@hostname

Additionally make sure required libraries such as GTK+ are properly installed.

Congratulations! You have successfully installed Eclipse IDE. Thanks for using this tutorial for installing Eclipse integrated development environment (IDE) on Rocky Linux 9 system. For additional help or useful information, we recommend you check the official Eclipse website.
