Usually, when you create a Java project you want to use functionalities made in another Java projects. For example, if your project wants to send one email you dont need to create all the necessary code for doing that. You can bring a java library that does the most part of the work. Maven is a building tool that will help you in several tasks. One of those tasks is to bring these external dependencies or artifacts to your project in an automatic way ( only with some configuration in a XML file ). Of course Maven has more details but, for your question this is enough. And, of course too, Maven can build your project as an artifact (usually a jar file ) that can be used or imported in other projects.

工件是项目可以使用或生成的元素。在Maven术语中，工件是Maven项目构建后生成的输出。例如，它可以是jar、war或任何其他可执行文件。

此外，Maven工件包括五个关键元素，groupId、artifactId、版本、打包和分类器。这些是我们用来识别工件的元素，被称为Maven坐标。

从这里开始阅读

工件是一个JAR或存储在存储库中的东西。Maven将它们取出并构建您的代码。

Maven在项目中组织其构建。

maven中的工件是由maven项目生成的资源。每个maven项目都可以有一个工件，比如罐子、战争、耳朵等。 项目的配置文件“pom.xml”描述了如何构建工件，如何运行单元测试等等。 通常，使用maven构建的软件项目由许多maven项目组成，这些maven项目构建了构成产品的工件(例如jar)。 如。

Root-Project   // produces no artifact, simply triggers the build of the other projects
  App-Project  // The application, that uses the libraries
  Lib1-Project // A project that creates a library (jar)
  Lib2-Project // Another library
  Doc-Project  // A project that generates the user documentation from some resources

Maven工件并不局限于java资源。你可以生成任何你需要的资源。例如文档、项目站点、zip-archives、本地库等。

Each maven project has a unique identifier consiting of [groupId, artifactId, version]. When a maven project requires resources of another project a dependency is configured in it's pom.xml using the above-mentioned identifier. Maven then automatically resolves the dependencies when a build is triggered. The artifacts of the required projects are then loaded either from the local repository, which is a simple directory in your user's home, or from other (remote) repositories specified in you pom.xml.

工件是部署到Maven存储库的文件，通常是JAR。

Maven构建生成一个或多个工件，例如编译后的JAR和“源”JAR。

每个工件都有一个组ID(通常是反向域名，如com.example.foo)、一个工件ID(只是一个名称)和一个版本字符串。三者合在一起唯一地识别了这个神器。

项目的依赖项被指定为工件。
