While IntelliJ has taken the lead, Eclipse remains critical for **legacy enterprise** projects and specific industries (Embedded, Auto). ## When to Use - **Legacy Projects**: Projects built with bespoke Eclipse plugins. - **OSGi / RCP**: Developing Eclipse plugins or Rich Client Platform apps. - **Free/Open Source**: Fully FOSS philosophy. ## Core Concepts ### Workspace Collection of Projects. ### Perspectives Layouts of views (Java Perspective, Debug Perspective). ### plugins The OSGi plugin system is the core of Eclipse. ## Best Practices (2025) **Do**: - **Use Eclipse Theia**: If you want a modern, VS Code-like experience built on Eclipse tech. - **Keep it Updated**: The quarterly rolling releases improve performance. **Don't**: - **Don't use for modern Web Dev**: It lags behind VS Code/WebStorm for JS/TS. ## References - [Eclipse Foundation](https://www.eclipse.org/) --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/g1joshi) — claim your Tome and manage your conversions.
