Maven

Apache Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central piece of information.

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:

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.

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.

EGerrit

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

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.

More details about Trace Compass can be found here.

 

Lua Development Tools (LDT)

Lua Development Tools (LDT) is about providing Lua developers with an IDE providing the user experience developers expect from any other tool dedicated to a static programming language.

Like many other dynamic languages, Lua is so flexible that it is hard to analyze enough to provide relevant and powerful tooling.
LDT is using Metalua, to analyze Lua source code and provide nice user assistance.
