The Eclipse Platform SDK includes all of the function from the basic Rich Client Platform, the optional plug-ins for enhancing generic applications, and the IDE-specific plug-ins. It also includes plug-ins that further refine the Eclipse Platform as a high-performance Java and Plug-in development environment.
The Java development tooling (JDT) plug-ins extend the platform workbench by providing specialized features for editing, viewing, compiling, debugging, and running Java code.
The JDT is installed as a set of plug-ins that are included in the SDK. The Java Development User Guide describes how to use the Java tools. The JDT Plug-in Developer Guide describes the structure and API of the JDT.
The Plug-in Development Environment (PDE) supplies tools that automate the creation, manipulation, debugging, and deploying of plug-ins.
The PDE is installed as a set of plug-ins that are included in the SDK. The PDE Guide describes how to use the environment.
