About the Eclipse Project
The Eclipse Project is an open source project of eclipse.org, overseen by a Project Management Committee (PMC) and project leaders. The work is done in subprojects working against Git repositories. The Eclipse Project Charter describes the organization of the project, roles and responsibilities of the participants, and top level development process for the project. The JDT and PDE are plug-in tools for the Eclipse Platform. Together, these three pieces form the Eclipse SDK download, a complete development environment for Eclipse-based tools, and for developing Eclipse itself.

The Platform defines the set of frameworks and common services that collectively make up "integration-ware" required to support the use of Eclipse as a component model, as a rich client platform (RCP) and as a comprehensive tool integration platform. These services and frameworks include a standard workbench user interface model and portable native widget toolkit, a project model for managing resources, automatic resource delta management for incremental compilers and builders, language-independent debug infrastructure, and infrastructure for distributed multi-user versioned resource management.
JDT - Java development tools
The JDT provides the tool plug-ins for the platform that implement a Java IDE for power-users, that supports the development of any Java application, including Eclipse plug-ins. The JDT adds the notion of Java projects and a Java perspective to the Eclipse platform, as well as a number of views, editors, wizards, builders, and code merging and refactoring tools. The JDT allows Eclipse to be a development environment for itself. The JDT plug-ins themselves can also be further extended by other tool builders.
PDE - Plug-in development environment
The PDE project provides a number of views and editors that make is easier to build plug-ins for Eclipse. Using the PDE, you can create your plug-in manifest file (plugin.xml), specify your plug-in runtime and other required plug-ins, define extension points, including their specific markup, associate XML Schema files with the extension point markup so extensions can be validated, create extensions on other plug-in extension points, etc. The PDE makes integrating plug-ins easy and fun.
e4 - the next generation of the Eclipse platform
The e4 project is an incubator for developing the next generation of the Eclipse platform. The mission of the e4 project is to build a next generation platform for pervasive, component-based applications and tools.
