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

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.

Kafka is a distributed streaming platform, which means:

• it can publish and subscribe to streams of records;

• it can store streams of records in a fault-tolerant way;

• it can process streams of records as they occur.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the compendium specification module, providing interfaces and classes for use in compiling bundles.

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.

The commons-pool package provides an object-pooling API and a number of object pool implementations. This package defines a handful of pooling interfaces and some base classes that may be useful when creating new pool implementations.

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 an API for caching accessed HTTP resources.

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.

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 provides a parser for command line arguments.

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.

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.

Although the java.net package provides basic functionality for accessing resources via HTTP, it doesn't provide the full flexibility or functionality needed by many applications. HttpClient seeks to fill this void by providing an efficient, up-to-date, and feature-rich package implementing the client side of the most recent HTTP standards and recommendations.

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

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.

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

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

Plexus Compiler is a Plexus component to use different compilers through a uniform API. This component chooses the compiler implementation to use in a project.

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.

This package provides the Eclipse core expression language with the org.eclipse.core.expressions module.

This package provides the Eclipse core file system with the module org.eclipse.core.filesystem.

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.

The Bean Scripting Framework (BSF) is a set of Java classes which provides scripting language support within Java applications, and access to Java objects and methods from scripting languages. BSF allows one to write JSPs in languages other than Java while providing access to the Java class library. In addition, BSF permits any Java application to be implemented in part (or dynamically extended) by a language that is embedded within it. This is achieved by providing an API that permits calling scripting language engines from within Java, as well as an object registry that exposes Java objects to these scripting language engines.
