Pax Exam creates OSGi bundles for testing purposes. It lets the user take control of the OSGi framework, the test framework (e.g. JUnit) and the system under test at the same time.

Xbean-reflect provides very flexible ways to create objects and graphs of objects for dependency injection frameworks

Woodstox is a stax XML API implementation.

Argparse4j is a command line argument parser library for Java based on Python's argparse module.

This package contains the runtime library used with generated sources by ANTLR.

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.

Java Compiler Compiler (JavaCC) is the most popular parser generator for use with Java applications. A parser generator is a tool that reads a grammar specification and converts it to a Java program that can recognize matches to the grammar. In addition to the parser generator itself, JavaCC provides other standard capabilities related to parser generation such as tree building (via a tool called JJTree included with JavaCC), actions, debugging, etc.

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.

Plexus-cipher contains a component to deal with encryption and decryption.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains a factory for JDBC connection factories. There are 3 preferred connection factories for getting JDBC connections:

• javax.sql.DataSource;

• javax.sql.ConnectionPoolDataSource;

• javax.sql.XADataSource.

Commons-compiler contains an API for janino, including the IExpressionEvaluator, IScriptEvaluator, IClassBodyEvaluator and ISimpleCompiler interfaces.

Eclipse Parsson is an implementation of the Jakarta JSON Processing specification.

This package contains the API used by components to manipulate compilers.

The JUnitParams project adds a new runner to JUnit and provides much easier and readable parametrised tests for JUnit.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains a repository service that contains resources.

Although the java.net package provides basic functionality for accessing resources via HTTP, it doesn't provide the full flexibility or functionality needed by many applications. HttpClient seeks to fill this void by providing an efficient, up-to-date, and feature-rich package implementing the client side of the most recent HTTP standards and recommendations.

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.

LZ4 - Java is a Java port of the popular lz4 compression algorithms and xxHash hashing algorithm.

APT stands for Annotation Processing Tool. APT provides a means for generating files and compiling new Java classes based on annotations found in your source code.

OPS4J stands for Open Participation Software for Java. This package contains utilities for storing and retrieving data from an InputStream.

This package contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. It builds on core streaming parser/generator package, and uses Jackson Annotations for configuration.

java-native-access-platform has cross-platform mappings and mappings for a number of commonly used platform functions, including a large number of Win32 mappings as well as a set of utility classes that simplify native access.

This package provides a library of matcher objects (also known as constraints or predicates) allowing match rules to be defined declaratively, to be used in other frameworks. Typical scenarios include testing frameworks, mocking libraries and UI validation rules.

This package provides the Eclipse core resource management module org.eclipse.core.resources.
