TestNG is a testing framework inspired from JUnit and NUnit but introducing some new functionalities that make it more powerful and easier to use.

This package is the Plexus Security Dispatcher Component. This component decrypts a string passed to it.

The AOP Alliance project is a joint project between several software engineering people who are interested in Aspect-Oriented Programming (AOP) and Java.

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.

Microemulator is a Java 2 Micro Edition (J2ME) CLDC/MIDP Emulator. It demonstrates MIDlet based applications in web browser applet and can be run as a standalone java application.

SVG Salamander is an SVG engine for Java that's designed to be small, fast, and allow programmers to use it with a minimum of fuss. It's in particular targeted for making it easy to integrate SVG into Java games and making it much easier for artists to design 2D game content - from rich interactive menus to charts and graphcs to complex animations.

This package contains an HTTP/1.1 compliant HTTP agent implementation. It also provides reusable components for client-side authentication, HTTP state management, and HTTP connection management.

Ant is a platform-independent build tool for Java. It is similar to make but is implemented using the Java language, requires the Java platform, and is best suited to building Java projects. Ant uses XML to describe the build process and its dependencies, whereas Make uses Makefile format.

Commons-Exec simplifies executing external processes.

AssertJ core is a Java library that provides a fluent interface for writing assertions. Its main goal is to improve test code readability and make maintenance of tests easier.

This package provides the native library for jansi, a small Java library that allows you to use ANSI escape sequences to format your console output.

The codec package contains simple encoder and decoders for various formats such as Base64 and Hexadecimal. In addition to these widely used encoders and decoders, the codec package also maintains a collection of phonetic encoding utilities.

This is a part of the Apache Commons Project.

OPS4J stands for Open Participation Software for Java. This package contains utilities and extensions related to java.lang.

Armed Bear Common Lisp (ABCL) is a full implementation of the Common Lisp language featuring both an interpreter and a compiler, running in the JVM. It supports JSR-223 (Java scripting API): it can be a scripting engine in any Java application. Additionally, it can be used to implement (parts of) the application using Java to Lisp integration APIs.

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.

This package provides the Java development kit OpenJDK.

Apache Commons Text is a library focused on algorithms working on strings.

This is a part of the Apache Commons Project.

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.

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

This is a word-aligned compressed variant of the Java Bitset class. It provides both a 64-bit and a 32-bit RLE-like compression scheme. It can be used to implement bitmap indexes.

The goal of word-aligned compression is not to achieve the best compression, but rather to improve query processing time. Hence, JavaEWAH tries to save CPU cycles, maybe at the expense of storage. However, the EWAH scheme is always more efficient storage-wise than an uncompressed bitmap (as implemented in the BitSet class by Sun).

EasyMock is a Java library that provides an easy way to use mock objects in unit testing.

This package provides the Java development kit OpenJDK.

The Daemon package from Apache Commons can be used to implement Java applications which can be launched as daemons. For example the program will be notified about a shutdown so that it can perform cleanup tasks before its process of execution is destroyed by the operation system.

This package contains the Java library. You will also need the actual binary for your architecture which is provided by the jsvc package.

This is a part of the Apache Commons Project.

ANTLR, ANother Tool for Language Recognition, (formerly PCCTS) is a language tool that provides a framework for constructing recognizers, compilers, and translators from grammatical descriptions containing Java, C#, C++, or Python actions. ANTLR provides excellent support for tree construction, tree walking, and translation.
