The JavaMail API provides a platform-independent and protocol-independent framework to build mail and messaging applications.

Plexus interpolator is a modular, flexible interpolation framework for the expression language style commonly seen in Maven, Plexus, and other related projects.

It has its foundation in the org.codehaus.plexus.utils.interpolation package within plexus-utils, but has been separated in order to allow these two libraries to vary independently of one another.

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.

Stax2 API is an extension to basic Stax 1.0 API that adds significant new functionalities, such as full-featured bi-direction validation interface and high-performance Typed Access API.

JOpt Simple is a Java library for parsing command line options, such as those you might pass to an invocation of javac. In the interest of striving for simplicity, as closely as possible JOpt Simple attempts to honor the command line option syntaxes of POSIX getopt and GNU getopt_long. It also aims to make option parser configuration and retrieval of options and their arguments simple and expressive, without being overly clever.

TLA+ is a high-level language for modeling programs and systems---especially concurrent and distributed ones. It's based on the idea that the best way to describe things precisely is with simple mathematics. TLA+ and its tools are useful for eliminating fundamental design errors, which are hard to find and expensive to correct in code.

The following TLA+ tools are available in this distribution:

• The Syntactic Analyzer: A parser and syntax checker for TLA+ specifications;

• TLC: A model checker and simulator for a subclass of "executable" TLA+ specifications;

• TLATeX: A program for typesetting TLA+ specifications;

• Beta test versions of 1-3 for the TLA+2 language; and

• The PlusCal translator.

Commons-Exec simplifies executing external processes.

The Apache Commons CLI library provides an API for parsing command line options passed to programs. It is also able to print help messages detailing the options available for a command line tool.

Commons CLI supports different types of options:

• POSIX like options (ie. tar -zxvf foo.tar.gz)

• GNU like long options (ie. du --human-readable --max-depth=1)

• Java like properties (ie. java -Djava.awt.headless=true Foo)

• Short options with value attached (ie. gcc -O2 foo.c)

• long options with single hyphen (ie. ant -projecthelp)

This is a part of the Apache Commons Project.

The Plexus project provides a full software stack for creating and executing software projects. Based on the Plexus container, the applications can utilise component-oriented programming to build modular, reusable components that can easily be assembled and reused. This package provides the Maven plugin generating the component metadata.

QDox is a high speed, small footprint parser for extracting class/interface/method definitions from source files complete with JavaDoc @tags. It is designed to be used by active code generators or documentation tools.

Java Servlet is the foundation web specification in the Java Enterprise Platform. Developers can build web applications using the Servlet API to interact with the request/response workflow. This project provides information on the continued development of the Java Servlet specification.

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.

BeanUtils provides a simplified interface to reflection and introspection to set or get dynamically determined properties through their setter and getter method.

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).

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.

This package is the jaxb annotations module for jackson.

ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files. It's widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build and walk parse trees.

XMLUnit provides you with the tools to verify the XML you emit is the one you want to create. It provides helpers to validate against an XML Schema, assert the values of XPath queries or compare XML documents against expected outcomes.

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

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-default-container is Plexus' inversion-of-control (IoC) container. It is composed of its public API and its default implementation.

The goal of this script is to provide a fast and lightweight script to enable responsive web designs in browsers that don't support CSS3 Media Queries.

This package provides Sanskrit stemmers and stopwords for the Lunr Javascript library.

DataTables is a table enhancing plug-in for the jQuery Javascript library, adding sorting, paging and filtering abilities to plain HTML tables with minimal effort.
