java-native-access-platform has cross-platform mappings and mappings for a number of commonly used platform functions, including a large number of Win32 mappings as well as a set of utility classes that simplify native access.

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.

This package provides annotations for the findbugs package. It provides packages in the javax.annotations namespace.

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.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the compendium specification module, providing interfaces and classes for use in compiling bundles.

The Java Collections Framework is the recognised standard for collection handling in Java. Commons-Collections seek to build upon the JDK classes by providing new interfaces, implementations and utilities. There are many features, including:

• Bag interface for collections that have a number of copies of each object

• BidiMap interface for maps that can be looked up from value to key as well and key to value

• MapIterator interface to provide simple and quick iteration over maps

• Transforming decorators that alter each object as it is added to the collection

• Composite collections that make multiple collections look like one

• Ordered maps and sets that retain the order elements are added in, including an LRU based map

• Reference map that allows keys and/or values to be garbage collected under close control

• Many comparator implementations

• Many iterator implementations

• Adapter classes from array and enumerations to collections

• Utilities to test or create typical set-theory properties of collections such as union, intersection, and closure.

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.

This package is the Plexus Security Dispatcher Component. This component decrypts a string passed to it.

JUnit is a simple framework to write repeatable tests for Java projects. JUnit provides assertions for testing expected results, test fixtures for sharing common test data, and test runners for running tests.

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.

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.

Java Message Service (JMS) API is used to send messages messages between two or more clients. It is a messaging standard that allows application components to create, send, receive, and read messages.

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

This project contains a set of libraries implementing a Java 1.0 - Java 11 Parser with advanced analysis functionalities.

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.

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.

SWT is a widget toolkit for Java designed to provide efficient, portable access to the user-interface facilities of the operating systems on which it is implemented.
