Error Prone is a static analysis tool for Java that catches common programming mistakes at compile-time. This package contains annotations used by programmers to guide the static analysis.

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.

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

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 contains the runtime library used with generated sources by ANTLR.

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.

SnakeYAML is a YAML processor for the Java Virtual Machine.

The Logging package is a thin bridge between different logging implementations. A library that uses the commons-logging API can be used with any logging implementation at runtime.

This package provides annotations for security. It provides packages in the javax.annotation and javax.annotation.security namespaces.

This package contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. It builds on core streaming parser/generator package, and uses Jackson Annotations for configuration.

This package provides the Java development kit OpenJDK built with the IcedTea build harness.

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.

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 is a library to help creating CLI around Plexus components.

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 an extension to earlier versions of easymock that allows mocking classes.

This package contains the base build API for maven and a default implementation of it. This API is about scanning files in a project and determining what files need to be rebuilt.

ANTLR, ANother Tool for Language Recognition, (formerly PCCTS) is a language tool that provides a framework for constructing recognizers, compilers, and translators from grammatical descriptions containing Java, C#, C++, or Python actions. ANTLR provides excellent support for tree construction, tree walking, and translation.
