Definition
Eclipse is a free, open-source integrated development environment (IDE) best known for Java development, built on an extensible plugin architecture that supports many other languages.
Overview
Eclipse was originally developed by IBM and released as open source in the early 2000s, later being placed under the independent Eclipse Foundation. For many years it was one of the most widely used Java IDEs, especially in enterprise development. Its core is an OSGi-based plugin framework (Equinox), meaning nearly all of Eclipse's functionality — the Java Development Tools (JDT), the C/C++ Development Tooling (CDT), and countless other language and tool integrations — is delivered as plugins on top of a generic tool-integration platform, rather than being hard-coded into a single application. It integrates with build tools like Apache Maven, and its large plugin ecosystem (the Eclipse Marketplace) covers everything from version control to application servers. Eclipse remains widely used for Java development, including with frameworks like Spring Boot, but general developer mindshare has shifted considerably toward alternatives such as VS Code and IntelliJ IDEA. Learning Java tooling in an Eclipse-style environment complements the material in SkillVeris's Java Spring Boot course.
