Eclipse was originally developed by IBM to replace the commercial software Visual Age for Java's next-generation IDE development environment. It was contributed to the open source community in November 2001. It is a non-profit Managed by the Eclipse Foundation, an alliance of software vendors.
While most users are happy to use Eclipse as a Java integrated development environment (IDE), Eclipse aims to be much more than that.
Eclipse also includes the Plug-in Development Environment (PDE), a component primarily aimed at software developers who wish to extend Eclipse because it allows them to build tools that integrate seamlessly with the Eclipse environment. Since everything in Eclipse is a plug-in, all tool developers have an equal role to play in providing plug-ins to Eclipse and providing users with a consistent and unified integrated development environment.
This equality and consistency is not limited to Java development tools. Although Eclipse is developed using the Java language, its use is not limited to the Java language; for example, plug-ins to support programming languages such as C/C++, COBOL, PHP, etc. are already available or expected to be released. The Eclipse framework can also be used as the basis for other application types not related to software development, such as content management systems.
