Eclipse IDE

Eclipse was the dominant Java IDE for a decade. 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.
