JLine is a Java library for handling console input. It is similar in functionality to BSD editline and GNU readline but with additional features that bring it on par with the Z shell line editor.

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

This package provides the Java development kit OpenJDK.

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.

Java-jboss-interceptors-api-spec implements the Interceptors API. Interceptors are used to interpose on business method invocations and specific events.

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-based solution for accessing, manipulating, and outputting XML data from Java code.

Plexus-archiver contains a component to deal with project archives (jar).

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

The Commons Lang components contains a set of Java classes that provide helper methods for standard Java classes, especially those found in the java.lang package. The following classes are included:

• StringUtils - Helper for java.lang.String.

• CharSetUtils - Methods for dealing with CharSets, which are sets of characters such as [a-z] and [abcdez].

• RandomStringUtils - Helper for creating randomised strings.

• NumberUtils - Helper for java.lang.Number and its subclasses.

• NumberRange - A range of numbers with an upper and lower bound.

• ObjectUtils - Helper for java.lang.Object.

• SerializationUtils - Helper for serializing objects.

• SystemUtils - Utility class defining the Java system properties.

• NestedException package - A sub-package for the creation of nested exceptions.

• Enum package - A sub-package for the creation of enumerated types.

• Builder package - A sub-package for the creation of equals, hashCode, compareTo and toString methods.

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.

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 a namespace with contracts.

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.

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.

Fest-test contains the common FEST testing infrastructure.

JEXL is a library intended to facilitate the implementation of dynamic and scripting features in applications and frameworks written in Java. JEXL implements an Expression Language based on some extensions to the JSTL Expression Language supporting most of the constructs seen in shell-script or ECMAScript. Its goal is to expose scripting features usable by technical operatives or consultants working with enterprise platforms.

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.

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.

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.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the OSGi org.osgi.service.event module.
