Overview

Eclipse is a free, open-source IDE originally built for Java and still most associated with it, though plugins extend it to C/C++, PHP, and other languages. It's maintained by the Eclipse Foundation and distributed as several preconfigured packages (Java, Java EE, C/C++, and more) via the Eclipse Installer.

It suits developers, students, and teams who want a no-cost, extensible IDE, particularly in enterprise Java environments where Eclipse has long been a default choice alongside IntelliJ IDEA. Its plugin ecosystem (via the Eclipse Marketplace) covers application servers, build tools, and version control integrations that many legacy Java shops still depend on.

Compared to IntelliJ IDEA, Eclipse's core editing and refactoring experience is generally considered less polished, and its plugin-based architecture can lead to inconsistent quality and occasional instability when multiple plugins are combined. Its main advantage is being fully free with no subscription tiers, which matters for students, hobbyists, and cost-sensitive organizations.

Eclipse's interface and workspace model (with its concept of a workspace directory tracking multiple projects) can feel dated compared to newer editors, and first-time setup of a full Java EE or Spring stack often requires installing several plugins to match a team's needs.

Key features

  • Java code editing with refactoring, debugging, and code completion
  • Preconfigured package variants for Java, Java EE, C/C++, and more
  • Eclipse Marketplace for installing additional language and tool plugins
  • Integrated Git support and support for other version control plugins
  • Built-in debugger with breakpoints, variable inspection, and step execution
  • Workspace model for managing multiple related projects together

System requirements

Operating system
Windows 11 and Windows 10 (64-bit); also available for macOS
Architecture
x64
Java
A Java Development Kit (JDK) is required; recent Eclipse packages bundle one or can use a system JDK

How to install Eclipse

  1. 1. Download the Eclipse Installer

    Get it from eclipse.org/downloads.

  2. 2. Choose a package

    Pick the preconfigured edition matching your work, such as Eclipse IDE for Java Developers.

  3. 3. Select a JDK

    Point the installer at an installed JDK, or let the package manage one for you.

  4. 4. Launch and set a workspace

    Choose a workspace folder on first launch — this is where Eclipse tracks your open projects.

How to use it

  1. 1. Import or create a project

    Use File > Import for existing codebases, or create a new project from a wizard.

  2. 2. Manage dependencies

    Use the Maven or Gradle integration (installed as needed) to manage project dependencies.

  3. 3. Debug your code

    Set breakpoints and use the Debug perspective to step through execution and inspect variables.

  4. 4. Extend via Marketplace

    Add plugins through Help > Eclipse Marketplace for frameworks or tools your project needs.

Safety and privacy

  • Download only from eclipse.org/downloads — third-party mirrors have historically bundled unwanted software with Eclipse installers.
  • Use the official Eclipse Installer rather than unverified archives found through search results.
Bundled software
The official installer itself does not bundle unrelated third-party software, but installing plugins from the Marketplace pulls in additional third-party code you should review before adding.
Privacy
Eclipse's base install does not require an account or transmit personal data beyond standard update checks; individual plugins may have their own data practices.

Known risks

  • Combining many third-party plugins can cause instability or slow startup times.
  • Older tutorials sometimes point to unofficial download mirrors — stick to eclipse.org.

What's new

  • Current release

    The Eclipse Foundation ships simultaneous releases on a regular cadence across its project family. Check eclipse.org for the release notes matching your installed version.

Pros and cons

Pros

  • Completely free and open source with no subscription tiers
  • Long-established in enterprise Java environments
  • Large plugin ecosystem covering many languages and frameworks
  • Multiple preconfigured package variants for different stacks

Cons

  • Editing and refactoring experience feels dated next to IntelliJ IDEA
  • Plugin-based extensibility can lead to instability
  • Workspace model takes some getting used to
  • Requires manually installing and managing a JDK

Verdict

Eclipse remains a solid, genuinely free option for Java development, especially in organizations with existing Eclipse-based tooling. Developers starting fresh without legacy ties often find IntelliJ IDEA's editing experience more comfortable today.

Frequently asked questions

Is Eclipse free?

Yes, Eclipse is free and open source under the Eclipse Public License, with no paid tiers.

Do I need to install Java separately?

Yes, some form of JDK is required; many Eclipse packages can download or use one automatically during setup.

Does Eclipse run on Windows 11?

Yes, Windows 11 and Windows 10 (64-bit) are both supported.

Is Eclipse only for Java?

No, plugins extend it to C/C++, PHP, and other languages, though Java remains its most mature and widely used configuration.
