OPS4J stands for Open Participation Software for Java. This package contains utilities and extensions related to handling streams and files.

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.

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

jsch-agent-proxy is a proxy program to OpenSSH's ssh-agent and Pageant included in Putty. This component contains an implementation of USocketFactory using JNA (Java Native Access).

Modello Java Plugin generates Java objects for the model.

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 in par with ZSH line editor. People familiar with the readline/editline capabilities for modern shells (such as bash and tcsh) will find most of the command editing features of JLine to be familiar.

This package includes the line reader.

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.

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.

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.

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 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.

This package provides the Java development kit OpenJDK.

Commons CSV reads and writes files in variations of the Comma Separated Value (CSV) format. The most common CSV formats are predefined in the CSVFormat class:

• Microsoft Excel

• Informix UNLOAD

• Informix UNLOAD CSV

• MySQL

• RFC 4180

• TDF

Custom formats can be created using a fluent style API.

Hdrhistogram creates histograms that support recording and analyzing sampled data value counts across a configurable integer value range with configurable value precision within the range. Value precision is expressed as the number of significant digits in the value recording, and provides control over value quantization behavior across the value range and the subsequent value resolution at any given level.

MVEL has largely been inspired by Java syntax, but has some fundamental differences aimed at making it more efficient as an expression language, such as operators that directly support collection, array and string matching, as well as regular expressions. MVEL is used to evaluate expressions written using Java syntax.

In addition to the expression language, MVEL serves as a templating language for configuration and string construction.

Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object. Gson can work with arbitrary Java objects including pre-existing objects that you do not have source-code of.

This package contains runtime libraries for Xbase languages such as Xtend.

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.

JGit is a lightweight, pure Java library implementing the Git version control system, providing repository access routines, support for network protocols, and core version control algorithms.

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 in par with ZSH line editor. People familiar with the readline/editline capabilities for modern shells (such as bash and tcsh) will find most of the command editing features of JLine to be familiar.

This package includes the Terminal API and implementations.

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.
