Eclipse Enterprise for Java (EE4J) is an open source initiative to create standard APIs, implementations of those APIs, and technology compatibility kits for Java runtimes that enable development,

Keti is a service that was designed to protect RESTfuls API using Attribute Based Access Control (ABAC).

The Eclipse User Storage Service SDK provides an idiomatic Java library for easy use of the USS by Eclipse RCP-based applications.

The Eclipse OMR project consists of a highly integrated set of open source C and C++ components that can be used to build robust language runtimes that will support many different hardware and operating system platforms. These components include but are not limited to: memory management, threading, platform port (abstraction) library, diagnostic file support, monitoring support, garbage collection, and native Just In Time compilation.

Eclipse MDHT delivers a standard object-oriented alternative to proprietary development methodologies and tooling used to specify and implement most healthcare industry standards.

Eclipse Golo is a dynamically-typed programming language for the Java Virtual Machine. Golo is largely interoperable with Java and other JVM languages (e.g., numeric types are boxing classes from java.lang, and collection literals leverage java.util classes). Golo supports imperative and functional programming patterns. Golo is not a strictly object-oriented programming language: it very much resembles Go in the sense that methods are just functions applied to specific receiver types. Golo or Java defined types can be augmented in Golo, that is, new methods can be made available.

Eclipse Papyrus-RT is an industrial-grade, complete modeling environment for the development of complex, software intensive, real-time, embedded, cyber-physical systems.

Eclipse Che is a developer workspace server and cloud IDE.  It is a next-generation Eclipse IDE. 

Eclipse Californium (Cf) is an open source implementation of the Constrained Application Protocol (CoAP). It is written in Java and targets unconstrained environments such as back-end service infrastructures (e.g., proxies, resource directories, or cloud services) and less constrained environments such as embedded devices running Linux (e.g., smart home/factory controllers or cellular gateways).

The Krikkit architecture is a publish/subscribe mechanism where rules/policies are registered on edge routers/gateways that have visibility into and communicate with sensors.
