Prerequisites

Before we begin, ensure you have the following:

• A Stable Internet Connection: You’ll need it to download the Eclipse installer and potentially other dependencies.
• A Compatible Operating System: Eclipse runs on Windows, macOS, and Linux. This guide covers all three.
• Java Development Kit (JDK): Eclipse requires a JDK to function correctly. Make sure you have a compatible version of the JDK installed and configured. This guide will provide instructions to verify it and to install it if needed. We highly recommend using JDK 17 or higher for optimal performance and compatibility.
• Administrative privileges (Optional): While not always strictly necessary, having admin privileges can simplify the installation process, especially on Windows.

Step-by-Step Installation Guide

Let’s dive into the installation process for each operating system:

I. Checking if JDK is Installed

Before installing Eclipse, it’s crucial to ensure that a compatible Java Development Kit (JDK) is installed on your system. Eclipse relies on the JDK to compile and execute Java programs.

For Windows:

1. Open Command Prompt (search for “cmd” in the start menu).
2. Type the following command and press Enter: java -version
3. If Java is installed, you’ll see the Java version information. Check if the version is 17 or above. If not go to the next step to download JDK.
4. Type the following command and press Enter: javac -version. This will check whether your java compiler is available

For macOS:

1. Open Terminal (search for “Terminal” in Spotlight).
2. Type the following command and press Enter: java -version
3. If Java is installed, you’ll see the Java version information. Check if the version is 17 or above. If not go to the next step to download JDK.
4. Type the following command and press Enter: javac -version. This will check whether your java compiler is available

For Linux:

1. Open Terminal.
2. Type the following command and press Enter: java -version
3. If Java is installed, you’ll see the Java version information. Check if the version is 17 or above. If not go to the next step to download JDK.
4. Type the following command and press Enter: javac -version. This will check whether your java compiler is available

If the java -version command returns an error or indicates a version lower than 17, you’ll need to download and install a JDK.

II. Downloading and Installing JDK

If you don’t have a JDK installed, or if it’s below version 17, follow these steps to download and install a suitable version:

1. Go to the Oracle JDK Download page: Visit the official Oracle website’s Java downloads page (https://www.oracle.com/java/technologies/downloads/). Choose the correct version for your system(jdk-17 or higher).
2. Download the JDK: Click on the appropriate download link for your operating system. It may ask you to create an account, create one and proceed with download.
3. Install the JDK:
   • Windows: Run the downloaded .exe file and follow the on-screen instructions. This involves clicking on “Next” on multiple pages. It is recommended to install it in the suggested location.
   • macOS: Open the downloaded .dmg file and follow the installation wizard. Drag and drop the .pkg file to install. Follow the steps in the installer.
   • Linux: The installation process can vary depending on your distribution, but usually involves unpacking the downloaded archive and then configuring the system environment variables. Often, .deb or .rpm file are used. It can also be done through package manager (sudo apt install openjdk-17-jdk for ubuntu based distributions).
4. Verify the installation: After the installation, repeat the `java -version` and `javac -version` commands in the terminal/command prompt to confirm that the newly installed JDK is working correctly.

III. Downloading Eclipse IDE

Now that you’ve verified or installed the JDK, you can proceed with downloading the Eclipse IDE.

1. Visit the Eclipse Downloads Page: Open your web browser and navigate to the official Eclipse downloads page (https://www.eclipse.org/downloads/).
2. Choose the Package: Look for “Eclipse IDE for Java Developers.” This package includes all the necessary tools for Java development.
3. Select Your Operating System: Click on the appropriate download link for your operating system (Windows, macOS, or Linux).
4. Start the Download: The download will begin. Depending on your internet speed, this may take some time.

IV. Installing Eclipse on Windows

After you’ve downloaded the installer for Windows, follow these steps:

1. Run the Installer: Double-click the downloaded .exe file to run the installer.
2. Select the Package: If the installer gives an option, choose “Eclipse IDE for Java Developers”.
3. Installation Directory: You can choose the installation directory, but the default is usually fine.
4. JDK selection The installer will give option to select the java virtual machine (JVM). If it cannot find the installed java location, then you can manually provide the location. If no java is installed or if it is older than version 17, you should install java first.
5. Create Start Menu Shortcut: Check the option to create a start menu shortcut if you want one.
6. Start the Installation Click on Install to start the installation. The installation may take a few minutes.
7. Launch Eclipse: Once the installation is complete, click on “Launch”.

V. Installing Eclipse on macOS

For macOS, the installation process involves these steps:

1. Extract the Archive: Double-click the downloaded .tar.gz or .zip file to extract its contents.
2. Move the Application: Drag the extracted “eclipse” folder to the “Applications” folder.
3. Launch Eclipse: Open the Applications folder and double-click the Eclipse application to launch it.
4. Security Prompt: The first time you launch it, macOS may ask for confirmation due to security reasons. Click on Open to allow the app to launch.
5. JDK selection The installer will give option to select the java virtual machine (JVM). If it cannot find the installed java location, then you can manually provide the location. If no java is installed or if it is older than version 17, you should install java first.

VI. Installing Eclipse on Linux

The installation process on Linux may vary slightly depending on your distribution. The following steps are generally applicable to most systems:

1. Extract the Archive: Open your terminal and navigate to the directory where you downloaded the .tar.gz or .zip file. Use the following command to extract the archive (replace eclipse-*.tar.gz with the actual filename):

   tar -xzvf eclipse-*.tar.gz

   or

   unzip eclipse-*.zip

2. Move to Installation Folder: Move the eclipse folder to your desired install directory (usually, /opt folder is used).

   sudo mv eclipse /opt/

3. Create a Shortcut (Optional): You can create a shortcut on your desktop or application menu. Create a desktop entry file by using a text editor.

   sudo nano /usr/share/applications/eclipse.desktop

   Add the following to the file (Modify the path according to your install location):

   [Desktop Entry]
   Type=Application
   Name=Eclipse
   Comment=Eclipse IDE
   Exec=/opt/eclipse/eclipse
   Icon=/opt/eclipse/icon.xpm
   Terminal=false
   Categories=Development;IDE;

   Save the file and make it executable:

   sudo chmod +x /usr/share/applications/eclipse.desktop

4. Launch Eclipse: From the application menu or using the executable from its location, open eclipse.
5. JDK selection The installer will give option to select the java virtual machine (JVM). If it cannot find the installed java location, then you can manually provide the location. If no java is installed or if it is older than version 17, you should install java first.
