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.

Java-cdi-api contains the required APIs for Contexts and Dependency Injection (CDI).

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.

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.

Bnd is a swiss army knife for OSGi, it creates manifest headers based on analyzing the class code, it verifies the project settings, it manages project dependencies, gives diffs jars, and much more.

Java Compiler Compiler (JavaCC) is the most popular parser generator for use with Java applications. A parser generator is a tool that reads a grammar specification and converts it to a Java program that can recognize matches to the grammar. In addition to the parser generator itself, JavaCC provides other standard capabilities related to parser generation such as tree building (via a tool called JJTree included with JavaCC), actions, debugging, etc.

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.

This project contains API and Compatible Implementation of Jakarta JSON Processing specification. Jakarta JSON Processing provides portable APIs to parse, generate, transform, and query JSON documents.

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

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

The org.apache.commons.jxpath package defines a simple interpreter of an expression language called XPath. JXPath applies XPath expressions to graphs of objects of all kinds: JavaBeans, Maps, Servlet contexts, DOM etc, including mixtures thereof.

This package provides a Java runtime environment for and Java development kit. It supports enhanced class redefinition (DCEVM), includes a number of improvements in font rendering, keyboards support, windowing/focus subsystems, HiDPI, accessibility, and performance, provides better desktop integration and bugfixes not yet present in OpenJDK.

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.

This package provides various Java utility classes for the Plexus framework to ease working with strings, files, command lines, XML and more.

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.

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

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.

This package contains an implementation of the JSR-341 specification for the expression language 3.0. It implements an expression language inspired by ECMAScript and XPath. This language is used with JavaServer Pages (JSP).

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.

Eclipse LSP4J provides Java bindings for the Language Server Protocol and the Debug Adapter Protocol. This package contains its LSP4J Java bindings for the Debug Server Protocol.

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.

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.

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.

Commons-Exec simplifies executing external processes.
