Hudson

Hudson is a continuous integration (CI) tool written in Java, which runs in a servlet container, such as Apache Tomcat or the GlassFish application server. It supports SCM tools including CVS, Subversion, Git and Clearcase and can execute Apache Ant and Apache Maven based projects, as well as arbitrary shell scripts and Windows batch commands. The Eclipse Foundation runs an instance of Hudson at https://hudson.eclipse.org/hudson/

Eclipse LSP4E

The project includes the necessary code to integrate any language server in the Eclipse IDE, interacting with the language server: it orchestrates the request to the language servers and presents the response in the usual IDE metaphors so users can manipulate them.
The default integration is to provide features into the Platform's Generic and Extensible editor, but some code may be used as API to let integration be done with other Eclipse-based editors.

Some examples of integration are:

Eclipse Collections

Eclipse Collections is a collections framework for Java. It has JDK-compatible List, Set and Map implementations with a rich API, additional types not found in the JDK like Bags, Multimaps and set of utility classes that work with any JDK compatible Collections, Arrays, Maps or Strings. The iteration protocol was inspired by the Smalltalk collection framework.

Eclipse Tools for Cloud Foundry

Eclipse Tools for Cloud Foundry (CFT) provide an extensible framework and common UI to deploy applications to different Cloud Foundry targets, and it is a framework that closely integrates with Web Tools Platform (WTP) and Eclipse. It allows application scaling and services management from the same Eclipse-based IDE where applications are developed. Applications can also be debugged on Cloud Foundry using the built-in Eclipse debugger. This makes it very convenient for developers to work on applications running on CF.

Model Driven Health Tools

MDHT delivers a standard object-oriented alternative to proprietary development methodologies and tooling used to specify and implement most healthcare industry standards. There are three primary categories of users for MDHT tools: authors of healthcare industry interoperability standards, certification or testing authorities who validate that an Electronic Health Record (EHR) system produces XML or JSON files that comply with the standard, and software developers that implement adapters or applications that produce and consume healthcare data.

Eclipse Package Drone

Eclipse Package Drone™ is a software artifact repository where OSGi™ bundles are first class citizens. The basic idea is, that through some process, be it a build or some manual upload, OSGi bundles get deployed to the repository. This can be restricted to specific named channels. In that way it is possible to tweak the code and the build process to a point where the developers are satisfied with the state of the channel and then it can be made public (e.g. a release).

Dirigible

Overview

Dirigible is an open source project that provides Integrated Development Environment as a Service (IDEaaS) as well as runtime containers integration for the running applications. The environment itself runs directly in browser and therefore does not require additional downloads and installations. It packs all the needed components, which makes it self-contained and well integrated software bundle that can be deployed on any Java based Web Server.

Eclipse Vorto

The Vorto project comprises of the meta information model, the tool set to create information models, the code generators and the repository to manage existing information models. The meta information model and also the tool set are based on the Eclipse EMF (Eclipse Modeling Framework) framework.

Eclipse Trace Compass

Eclipse Trace Compass is an open source application for viewing and analyzing any type of logs or traces. Its goal is to provide views, graphs, metrics, and more to help extract useful information from traces, in a way that is more user-friendly and informative than huge text dumps.
