This package contains shared language features of the Java language, for the plexus project.

Java-jboss-transaction-api-spec implements the Transactions API. A transaction is a unit of work containing one or more operations involving one or more shared resources having ACID (Atomicity, Consistency, Isolation and Durability) properties.

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.

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.

Xbean-reflect provides very flexible ways to create objects and graphs of objects for dependency injection frameworks

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains an interface and utilitary classes for promises. A Promise represents a future value. It handles the interactions for asynchronous processing.

Jakarta Activation lets you take advantage of standard services to: determine the type of arbitrary piece of data; encapsulate access to it; discover the operations available on it; and instantiate the appropriate bean to perform the operation(s).

Jansi is a Java library that allows you to use ANSI escape sequences to format your console output which works on every platform.

LIBANTLR3C provides run-time C libraries for ANTLR3 (ANother Tool for Language Recognition v3).

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.

This package contains the Javac Compiler support for Plexus Compiler component.

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.

This package provides the Eclipse core file system with the module org.eclipse.core.filesystem.

Javassist (JAVA programming ASSISTant) makes Java bytecode manipulation simple. It is a class library for editing bytecodes in Java; it enables Java programs to define a new class at runtime and to modify a class file when the JVM loads it.

JAX-RS provides a standardized API for building RESTful web services in Java.

OpenJFX is a client application platform for desktop, mobile and embedded systems built on Java. Its goal is to produce a modern, efficient, and fully featured toolkit for developing rich client applications. This package contains base classes for the OpenJFX distribution.

The Daemon package from Apache Commons can be used to implement Java applications which can be launched as daemons. For example the program will be notified about a shutdown so that it can perform cleanup tasks before its process of execution is destroyed by the operation system.

This package contains the Java library. You will also need the actual binary for your architecture which is provided by the jsvc package.

This is a part of the Apache Commons Project.

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).

The Byte Code Engineering Library (Apache Commons BCEL) is intended to give users a convenient way to analyze, create, and manipulate (binary) Java class files. Classes are represented by objects which contain all the symbolic information of the given class: methods, fields and byte code instructions, in particular.

Such objects can be read from an existing file, be transformed by a program (e.g. a class loader at run-time) and written to a file again. An even more interesting application is the creation of classes from scratch at run-time. The Byte Code Engineering Library (BCEL) may be also useful if you want to learn about the Java Virtual Machine (JVM) and the format of Java .class files.

This package provides support for the Eclipse extension registry.

Eclipse LSP4J provides Java bindings for the Language Server Protocol and the Debug Adapter Protocol. This package is a common definition intended to be inherited by other packages.

Conversant Disruptor is the highest performing intra-thread transfer mechanism available in Java. Conversant Disruptor is an implementation of this type of ring buffer that has almost no overhead and that exploits a particularly simple design.

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.

Apache Felix Resolver implements the OSGi resolver specification, providing dependency resolution for OSGi bundles.
