JUnit is a unit testing framework for the Java programming language. JUnit has been important in the development of test-driven development, and is one of a family of unit testing frameworks which is collectively known as xUnit that originated with SUnit.
Apache Ant is a software tool for automating software build processes which originated from the Apache Tomcat project in early 2000 as a replacement for the Make build tool of Unix. It is similar to Make, but is implemented using the Java language and requires the Java platform. Unlike Make, which uses the Makefile format, Ant uses XML to describe the code build process and its dependencies.
Maven is a build automation tool used primarily for Java projects. Maven can also be used to build and manage projects written in C#, Ruby, Scala, and other languages. The Maven project is hosted by The Apache Software Foundation, where it was formerly part of the Jakarta Project.
Build automation is the process of automating the creation of a software build and the associated processes including: compiling computer source code into binary code, packaging binary code, and running automated tests.
Apache Gump is an open source continuous integration system, which aims to build and test all the open source Java projects, every night. Its aim is to make sure that all the projects are compatible, at both the API level and in terms of functionality matching specifications. It is hosted at gump.apache.org, and runs every night on the official Sun JVM.
A software repository, or repo for short, is a storage location for software packages. Often a table of contents is also stored, along with metadata. A software repository is typically managed by source or version control, or repository managers. Package managers allow automatically installing and updating repositories, sometimes called "packages".
The Buckminster Project is an Eclipse (software) technology sub-project focused on component assembly. Buckminster facilitates straightforward sharing of complex assemblies of software components. It is particularly useful for building and sharing virtual distros, distributions of software components which share components across multiple software projects and repositories. In February 2019 project was archived.
Spring Roo is an open-source software tool that uses convention-over-configuration principles to provide rapid application development of Java-based enterprise software. The resulting applications use common Java technologies such as Spring Framework, Java Persistence API, Thymeleaf, Apache Maven and AspectJ. Spring Roo is a member of the Spring portfolio of projects.
Virgo is an open source, OSGi-based, Java application server. Virgo supports the deployment of OSGi bundles and unmodified Java web applications as well as OSGi-influenced Shared Libraries WARs and Shared Services WARs.
sbt is an open-source build tool created explicitly for Scala and Java projects. It aims to streamline the procedure of constructing, compiling, testing, and packaging applications, libraries, and frameworks. sbt is highly adaptable, permitting developers to customize the build process according to their project's specific needs.
Gradle is a build automation tool for multi-language software development. It controls the development process in the tasks of compilation and packaging to testing, deployment, and publishing. Supported languages include Java, C/C++, and JavaScript. Gradle builds on the concepts of Apache Ant and Apache Maven, and introduces a Groovy- and Kotlin-based domain-specific language contrasted with the XML-based project configuration used by Maven. Gradle uses a directed acyclic graph to determine the order in which tasks can be run, through providing dependency management. It runs on the Java Virtual Machine.
Java code coverage tools are of two types: first, tools that add statements to the Java source code and require its recompilation. Second, tools that instrument the bytecode, either before or during execution. The goal is to find out which parts of the code are tested by registering the lines of code executed when running a test.
Apache Allura is an open-source forge software for managing source code repositories, bug reports, discussions, wiki pages, blogs and more for any number of individual projects. Allura graduated from incubation with the Apache Software Foundation in March 2013.
Bazel is a free and open-source software tool used for the automation of building and testing software. Google uses the build tool Blaze internally and released an open-sourced port of the Blaze tool as Bazel, named as an anagram of Blaze. Bazel was first released in March 2015 and was in beta status by September 2015. Version 1.0 was released in October 2019.
Grunt is a JavaScript task runner, a tool used to automatically perform frequent tasks such as minification, compilation, unit testing, and linting. It uses a command-line interface to run custom tasks defined in a file. Grunt was created by Ben Alman and is written in Node.js. It is distributed via npm. As of October 2022, there were more than 6,000 plugins available in the Grunt ecosystem.
Spring Boot Extension is Spring's convention-over-configuration solution intended to aid in creating production-grade Spring applications with minimal amounts of configuration. Most of the application can be preconfigured using Spring team's "opinionated view" of the best configuration and use of the Spring platform and third-party libraries. A Spring Boot application can be written using several programming languages, including Java and Kotlin.
In version-control systems, a monorepo is a software-development strategy in which the code for a number of projects is stored in the same repository. This practice dates back to at least the early 2000s, when it was commonly called a shared codebase. Google, Meta, Microsoft, Uber, Airbnb, and Twitter all employ very large monorepos with varying strategies to scale build systems and version control software with a large volume of code and daily changes.
