如RCP教程详情
Plugins are the smallest deployable and installable software components of Eclipse.
Each plugin can define extension-points which define possibilities for functionality contributions (code and non-code) by other plugins. Non-code functionality contributions can, for example, provide help content.
The basis for this architecture is the runtime environment Equinox of Eclipse which is the reference implementation of OSGI. See OSGi development - Tutorialfor details.
The Plugin concept of Eclipse is the same as the bundle concept of OSGI. Generally speaking a OSGI bundle equals a Plugin and vice-versa.
插件是 Eclipse 中最小的可部署和可安装的软件组件。
每个插件都可以定义扩展点，这些扩展点定义了其他插件的功能贡献（代码和非代码）的可能性。例如，非代码功能贡献可以提供帮助内容。
该架构的基础是 Eclipse 的运行时环境 Equinox，它是 OSGI 的参考实现。有关详细信息，请参阅OSGi 开发 - 教程。
Eclipse 的 Plugin 概念与 OSGI 的 bundle 概念相同。一般来说，OSGI 包等同于插件，反之亦然。
The Feature Tutorialmentions
该功能教程提到
A feature project is basically a list of plugins and other features which can be understood as a logical separate unit.
Eclipse uses feature projects for the updates manager and for the build process. You can also supply a software license with a feature
一个功能项目基本上是一个插件和其他功能的列表，可以理解为一个逻辑上的独立单元。
Eclipse 将特性项目用于更新管理器和构建过程。您还可以提供具有功能的软件许可证
Finally, a productis a stand-alone program built with the Eclipse platform. A product may optionally be packaged and delivered as one or more features, which are simply groupings of plug-ins that are managed as a single entity by the Eclipse update mechanisms.
最后，产品是使用 Eclipse 平台构建的独立程序。一个产品可以有选择地作为一个或多个特性打包和交付，这些特性只是由 Eclipse 更新机制作为单个实体管理的插件的简单分组。
So:
所以：
plugins can be grouped into features which can be packaged as one executable unit called product.
插件可以分组为功能，这些功能可以打包为一个名为 product 的可执行单元。
