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.

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

Joda-Convert provides a small set of classes to aid conversion between Objects and Strings. It is not intended to tackle the wider problem of Object to Object transformation.

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.

Drip is a launcher for the Java Virtual Machine that provides much faster startup times than the java command. The drip script is intended to be a drop-in replacement for the java command, only faster.

The Apache Commons Net library implements the client side of many basic Internet protocols. The purpose of the library is to provide fundamental protocol access, not higher-level abstractions.

This package provides the Java development kit OpenJDK.

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

OPS4J stands for Open Participation Software for Java. This package contains utilities for obtaining services via the Java SE 6 ServiceLoader.

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

This library implements concurrent data structures that are not natively available in Java.

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 is the GNU servlet API distribution, part of the ClasspathX project. It provides implementations of version 3.0 of the servlet API and version 2.1 of the Java ServerPages API.

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.

This package provides the Eclipse core variables module org.eclipse.core.variables.

Commons-Exec simplifies executing external processes.

Dataformat backends are used to support format alternatives to JSON, supported by default. This is done by sub-classing Jackson core abstractions.

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

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.

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.

Xerial is a set of data management libraries for the Java programming language. The ultimate goal of the Xerial project is to manage everything as database, including class objects, text format data, data streams, etc.

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.

JNA provides Java programs easy access to native shared libraries without writing anything but Java code - no JNI or native code is required. JNA allows you to call directly into native functions using natural Java method invocation.

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.
