This package provides the core libraries of the Eclipse Java development tools.

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

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.

OPS4J stands for Open Participation Software for Java. This package contains utilities for storing and retrieving data from an InputStream.

SLF4J binding for the Simple implementation, which outputs all events to System.err. Only messages of level INFO and higher are printed.

This package provides the Java development kit OpenJDK.

JSON Processing (JSON-P) is a Java API to process (e.g. parse, generate, transform and query) JSON messages. It produces and consumes JSON text in a streaming fashion (similar to StAX API for XML) and allows building a Java object model for JSON text using API classes (similar to DOM API for XML).

JCommander is a very small Java framework that makes it trivial to parse command line parameters. Parameters are declared with annotations.

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.

Eclipse LSP4J provides Java bindings for the Language Server Protocol and the Debug Adapter Protocol. This package contains its JSON-RPC implementation's debug protocol.

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.

This package provides the Eclipse preferences mechanism with the module org.eclipse.equinox.preferences.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the Data Transfer Objects. It is easily serializable having only public fields of primitive types and their wrapper classes, Strings, and DTOs. List, Set, Map and array aggregates may also be used. The aggregates must only hold objects of the listed types or aggregates.

jakarta-regexp is an old regular expression parser generator for Java.

AssertJ core is a Java library that provides a fluent interface for writing assertions. Its main goal is to improve test code readability and make maintenance of tests easier.

jsch-agent-proxy is a proxy program to OpenSSH's ssh-agent and Pageant included in Putty. This component contains an implementation of USocketFactory using JNA (Java Native Access).

jsch-agent-proxy is a proxy program to OpenSSH's ssh-agent and Pageant included in Putty. This component contains a library to use jsch-agent-proxy with JSch.

Plexus classworlds replaces the native ClassLoader mechanism of Java. It is especially useful for dynamic loading of application components.

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.

BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java. BeanShell dynamically executes standard Java syntax and extends it with common scripting conveniences such as loose types, commands, and method closures like those in Perl and JavaScript.

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

JSch is a pure Java implementation of SSH2. JSch allows you to connect to an SSH server and use port forwarding, X11 forwarding, file transfer, etc., and you can integrate its functionality into your own Java programs.
