Logback is intended as a successor to the popular log4j project. This module can be assimilated to a significantly improved version of log4j. Moreover, logback-classic natively implements the slf4j API so that you can readily switch back and forth between logback and other logging frameworks such as log4j or java.util.logging (JUL).

This package specifies a means for obtaining objects in such a way as to maximize reusability, testability and maintainability compared to traditional approaches such as constructors, factories, and service locators (e.g., JNDI). This process, known as dependency injection, is beneficial to most nontrivial applications.

Many types depend on other types. For example, a Stopwatch might depend on a TimeSource. The types on which a type depends are known as its dependencies. The process of finding an instance of a dependency to use at run time is known as resolving the dependency. If no such instance can be found, the dependency is said to be unsatisfied, and the application is broken.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the support annotations for metatype.

This package contains Jackson extension component for reading and writing XML encoded data.

Further, the goal is to emulate how JAXB data-binding works with "Code-first" approach (that is, no support is added for "Schema-first" approach). Support for JAXB annotations is provided by JAXB annotation module; this module provides low-level abstractions (JsonParser, JsonGenerator, JsonFactory) as well as small number of higher level overrides needed to make data-binding work.

This package provides the Eclipse content mechanism in the org.eclipse.core.contenttype module.

JMock is a library that supports test-driven development of Java code with mock objects. Mock objects help you design and test the interactions between the objects in your programs.

The jMock library

• makes it quick and easy to define mock objects

• lets you precisely specify the interactions between your objects, reducing the brittleness of your tests

• plugs into your favourite test framework

• is easy to extend.

Tinybundles is all about creating OSGi related artifacts like Bundles, Fragments and Deployment Packages with Java Api. It is very convenient to create such artifacts on-the-fly inside Tests (like in Pax Exam). On the other hand, this library can be a foundation of real end user tools that need to create those artifacts.

Jeromq provides the java bindings for 0MQ.

This package contains an implementation of the JSR-341 specification for the expression language 3.0. It implements an expression language inspired by ECMAScript and XPath. This language is used with JavaServer Pages (JSP).

This package provides the Java development kit OpenJDK.

This package contains shared language features of the Java language, for the plexus project.

This project contains API and Compatible Implementation of Jakarta JSON Processing specification. Jakarta JSON Processing provides portable APIs to parse, generate, transform, and query JSON documents.

ASM is an all purpose Java bytecode manipulation and analysis framework. It can be used to modify existing classes or dynamically generate classes, directly in binary form. The provided common transformations and analysis algorithms allow easily assembling custom complex transformations and code analysis tools.

BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java. BeanShell dynamically executes standard Java syntax and extends it with common scripting conveniences such as loose types, commands, and method closures like those in Perl and JavaScript.

Eclipse LSP4J provides Java bindings for the Language Server Protocol and the Debug Adapter Protocol. This package contains its JSON-RPC implementation.

PowerMock is a framework that extends other mock libraries such as EasyMock with more powerful capabilities. PowerMock uses a custom classloader and bytecode manipulation to enable mocking of static methods, constructors, final classes and methods, private methods, removal of static initializers and more. By using a custom classloader no changes need to be done to the IDE or continuous integration servers which simplifies adoption.

This package provides the core libraries of the Eclipse Java development tools.

Joda-Convert provides a small set of classes to aid conversion between Objects and Strings. It is not intended to tackle the wider problem of Object to Object transformation.

Jakarta Annotations defines a collection of annotations representing common semantic concepts that enable a declarative style of programming that applies across a variety of Java technologies.

Openchart2 provides a simple, yet powerful, interface for Java programmers to create two-dimensional charts and plots. The library features an assortment of graph styles, including advanced scatter plots, bar graphs, and pie charts.

StringTemplate is a java template engine (with ports for C#, Objective-C, JavaScript, Scala) for generating source code, web pages, emails, or any other formatted text output. StringTemplate is particularly good at code generators, multiple site skins, and internationalization / localization. StringTemplate also powers ANTLR.

Modello Java Plugin generates Java objects for the model.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the names for the attributes and directives for an extender namespace.

This package provides the Java development kit OpenJDK.
