This package provides the Eclipse core resource management module org.eclipse.core.resources.

FEST-Assert provides a fluent interface for assertions.

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

JSON Processing (JSON-P) is a Java API to process (e.g. parse, generate, transform and query) JSON messages. This package contains a reference implementation of that API.

JMH is a Java harness for building, running, and analysing nano/micro/milli/macro benchmarks written in Java and other languages targeting the JVM.

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 HTTP/1.1 compliant HTTP agent implementation. It also provides reusable components for client-side authentication, HTTP state management, and HTTP connection management.

Guice is a lightweight dependency injection framework for Java 6 and above.

Commons-compiler contains an API for janino, including the IExpressionEvaluator, IScriptEvaluator, IClassBodyEvaluator and ISimpleCompiler interfaces.

Commons VFS provides a single API for accessing various different file systems. It presents a uniform view of the files from various different sources, such as the files on local disk, on an HTTP server, or inside a Zip archive.

This is a word-aligned compressed variant of the Java Bitset class. It provides both a 64-bit and a 32-bit RLE-like compression scheme. It can be used to implement bitmap indexes.

The goal of word-aligned compression is not to achieve the best compression, but rather to improve query processing time. Hence, JavaEWAH tries to save CPU cycles, maybe at the expense of storage. However, the EWAH scheme is always more efficient storage-wise than an uncompressed bitmap (as implemented in the BitSet class by Sun).

HawtJNI is a code generator that produces the JNI code needed to implement Java native methods. It is based on the jnigen code generator that is part of the SWT Tools project.

Plexus IO is a set of plexus components, which are designed for use in I/O operations. This implementation using plexus components allows reusing it in maven.

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

OPS4J stands for Open Participation Software for Java. This package contains utilities and extensions related to resolving properties from different sources.

Plexus-default-container is Plexus' inversion-of-control (IoC) container. It is composed of its public API and its default implementation.

HttpCore is a set of low level HTTP transport components that can be used to build custom client and server side HTTP services with a minimal footprint. HttpCore supports two I/O models: blocking I/O model based on the classic Java I/O and non-blocking, event driven I/O model based on Java NIO.

This package provides the non-blocking I/O model library based on Java NIO.

Fest-test contains the common FEST testing infrastructure.

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.

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

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.

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.

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.

OPS4J stands for Open Participation Software for Java. This package contains utilities and extensions related to environment, i18n and mime types.
