Pure Java implementation of the NaCl: Networking and Cryptography library.

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

This package provides the Eclipse core variables module org.eclipse.core.variables.

Java Compiler Compiler (JavaCC) is the most popular parser generator for use with Java applications. A parser generator is a tool that reads a grammar specification and converts it to a Java program that can recognize matches to the grammar. In addition to the parser generator itself, JavaCC provides other standard capabilities related to parser generation such as tree building (via a tool called JJTree included with JavaCC), actions, debugging, etc.

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.

TreeLayout creates tree layouts for arbitrary trees. It is not restricted to a specific output or format, but can be used for any kind of two dimensional diagram. Examples are Swing based components, SVG files, etc. This is possible because TreeLayout separates the layout of a tree from the actual rendering.

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

This library is used in the legacy build process of several key frameworks developed by ObjectWeb, among them legacy versions of the ObjectWeb ASM bytecode manipulation framework.

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

This package provides the Java development kit OpenJDK.

This package provides the ant build tool core libraries with the module org.eclipse.ant.core.

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).

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.

This package contains Jackson extension component for reading and writing XML encoded data.

Further, the goal is to emulate how JAXB data-binding works with "Code-first" approach (that is, no support is added for "Schema-first" approach). Support for JAXB annotations is provided by JAXB annotation module; this module provides low-level abstractions (JsonParser, JsonGenerator, JsonFactory) as well as small number of higher level overrides needed to make data-binding work.

Sisu is a modular JSR330-based container that supports classpath scanning, auto-binding, and dynamic auto-wiring. Sisu uses Google-Guice to perform dependency injection and provide the core JSR330 support, but removes the need to write explicit bindings in Guice modules. Integration with other containers via the Eclipse Extension Registry and the OSGi Service Registry is a goal of this project.

This package provides the Java development kit OpenJDK.

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

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.

jsch-agent-proxy is a proxy program to OpenSSH's ssh-agent and Pageant included in Putty. This component contains the code for a proxy to pageant.

The Byte Code Engineering Library (Apache Commons BCEL) is intended to give users a convenient way to analyze, create, and manipulate (binary) Java class files. Classes are represented by objects which contain all the symbolic information of the given class: methods, fields and byte code instructions, in particular.

Such objects can be read from an existing file, be transformed by a program (e.g. a class loader at run-time) and written to a file again. An even more interesting application is the creation of classes from scratch at run-time. The Byte Code Engineering Library (BCEL) may be also useful if you want to learn about the Java Virtual Machine (JVM) and the format of Java .class files.

Byte Buddy is a code generation and manipulation library for creating and modifying Java classes during the runtime of a Java application and without the help of a compiler.

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.

Modello Java Plugin generates Java objects for the model.

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