OPS4J stands for Open Participation Software for Java. This package contains utilities for obtaining services via the Java SE 6 ServiceLoader.

This library implements concurrent data structures that are not natively available in Java.

The JUnitParams project adds a new runner to JUnit and provides much easier and readable parametrised tests for JUnit.

This package provides compile-time annotations such as @SuppressFBWarnings and @ExcludeFromCodeCoverageGeneratedReport.

The modello test package contains the basis to create Modello generator unit-tests, including sample models and xml files to test every feature for every plugin.

Modello XML Plugin contains shared code for every plugins working on XML representation of the model.

OpenJFX is a client application platform for desktop, mobile and embedded systems built on Java. Its goal is to produce a modern, efficient, and fully featured toolkit for developing rich client applications. This package contains base classes for the OpenJFX distribution.

Pax Exam creates OSGi bundles for testing purposes. It lets the user take control of the OSGi framework, the test framework (e.g. JUnit) and the system under test at the same time.

Commons Math is a library of lightweight, self-contained mathematics and statistics components addressing the most common problems not available in the Java programming language or Commons Lang.

This package contains runtime libraries for Xbase languages such as Xtend.

Apache Felix is a community effort to implement the OSGi Framework and Service platform.

XMLUnit provides you with the tools to verify the XML you emit is the one you want to create. It provides helpers to validate against an XML Schema, assert the values of XPath queries or compare XML documents against expected outcomes.

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

This package provides the Java development kit OpenJDK.

The Jakarta-ORO Java classes are a set of text-processing Java classes that provide Perl5 compatible regular expressions, AWK-like regular expressions, glob expressions, and utility classes for performing substitutions, splits, filtering filenames, etc. This library is the successor of the OROMatcher, AwkTools, PerlTools, and TextTools libraries originally from ORO, Inc.

Ivy is a tool for managing (recording, tracking, resolving and reporting) project dependencies. It is characterized by the following:

• flexibility and configurability - Ivy is essentially process agnostic and is not tied to any methodology or structure. Instead it provides the necessary flexibility and configurability to be adapted to a broad range of dependency management and build processes.

• tight integration with Apache Ant - while available as a standalone tool, Ivy works particularly well with Apache Ant providing a number of powerful Ant tasks ranging from dependency resolution to dependency reporting and publication.

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.

Janino is a Java compiler. Janino can compile a set of source files to a set of class files like javac, but also compile a Java expression, block, class body or source file in memory, load the bytecode and execute it directly in the same JVM. janino can also be used for static code analysis or code manipulation.

Parallel Java (PJ) is an API and middleware for parallel programming in 100% Java on shared memory multiprocessor (SMP) parallel computers, cluster parallel computers, and hybrid SMP cluster parallel computers.

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.

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 Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction for various logging frameworks (e.g. java.util.logging, logback, log4j) allowing the end user to plug in the desired logging framework at deployment time.

This library supplies some utility classes needed for libraries from the SIS division at ETH Zurich like jHDF5.

Picocli is a framework for building command line applications for the JVM. It supports colors, autocompletion, subcommands, and more. Written in Java, usable from Groovy, Kotlin, Scala, etc.
