Looking to download and install Eclipse Mars on Windows?

Good news!

I’m going to explain you where you can find the package.

I’ll also guide you through the different installation steps.

Let’s go!

Check following post if you are looking to download and install Eclipse Neon or Eclipse Photon.

What is Eclipse?

Eclipse is an integrated development environment (IDE). Its primary use is for developing Java applications. But other programming languages are also supported.

The initial Eclipse codebase originated from IBM VisualAge. Today it is free and open-source software maintained by the Eclipse Foundation.

Step #1: Prerequisites

Eclipse requires Java to run. Let’s check if you have Java installed on your system.

Click on the Windows button. Then type “cmd” in the search box.

Click on the cmd shortcut.

windows search cmd

Wait for the command prompt to open.

Type “java -version” and press ENTER.

If you do not have Java installed on your system. Check following post which details how to install a Java Development Kit on Windows 10.

Step #2: Download

Head over to the Eclipse Mars 2 Packages download page.

We will download the Eclipse IDE for Java EE Developers package.

Click on your Windows version. This needs to match with the Java version installed on your system!

In this guide, we will install the 64-bit version.
