Tycho

Tycho is focused on a Maven-centric, manifest-first approach to building Eclipse plug-ins, features, update sites, RCP applications and OSGi bundles.

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:

EclEmma

EclEmma is a free Java code coverage tool for Eclipse, available under the Eclipse Public License.

It brings code coverage analysis directly into the Eclipse workbench:

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 ChemClipse

Eclipse ChemClipse supports the user to analyse data acquired from systems used in analytical chemistry. In particular, chromatography coupled with mass spectrometry (GC/MS) or flame-ionization detectors (GC/FID) is used to identify and/or monitor chemical substances. It's an important task e.g. for quality control issues.

EGerrit

The purpose of this project is to provide a set of Eclipse plug-ins that provide code review capabilities in the Eclipse IDE.

Andmore - Eclipse Android Tooling

The project develops and maintains technologies for creating Android applications. This ranges from creating new Eclipse components and updating existing components that support Android development to a downloadable package that can be used for new developers and students. The project will maintain parity with current development trends in phones, tablets, smart watches, smart TVs, embedded Android, and future directions for Android development.

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.
