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

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the log service.

This package contains a set of Java annotations which can be used in JVM-based languages. They serve as an additional documentation and can be interpreted by IDEs and static analysis tools to improve code analysis.

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

Logback is intended as a successor to the popular log4j project. This module lays the groundwork for the other two modules.

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.

Java Servlet is the foundation web specification in the Java Enterprise Platform. Developers can build web applications using the Servlet API to interact with the request/response workflow. This project provides information on the continued development of the Java Servlet specification.

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

MapDB provides concurrent maps, sets and queues backed by disk storage or off-heap memory.

This package is a Maven plugin to generate Plexus descriptors from source tags and class annotations.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the OSGi Core module.

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).

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.

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 in par with ZSH line editor. People familiar with the readline/editline capabilities for modern shells (such as bash and tcsh) will find most of the command editing features of JLine to be familiar.

This package includes the line reader.

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.

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.

OPS4J stands for Open Participation Software for Java. This package contains utilities and extensions related to java.lang.

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

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).

Plexus-cipher contains a component to deal with encryption and decryption.

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.

This package contains general purpose annotations for the Jackson Data Processor, used on value and handler types. The only annotations not included are ones that require dependency to the Databind package.

Microemulator is a Java 2 Micro Edition (J2ME) CLDC/MIDP Emulator. It demonstrates MIDlet based applications in web browser applet and can be run as a standalone java application.

This package provides the HttpCore benchmarking tool. It is an Apache AB clone based on HttpCore.
