A Project Object Model or POM is the fundamental unit of work in Maven. It is an XML file that contains information about the project and configuration details used by Maven to build the project. It contains default values for most projects. Examples for this is the build directory, which is target; the source directory, which is src/main/java; the test source directory, which is src/main/test; and so on.
The POM was renamed from project.xml in Maven 1 to pom.xml in Maven 2. Instead of having a maven.xml file that contains the goals that can be executed, the goals or plugins are now configured in the pom.xml. When executing a task or goal, Maven looks for the POM in the current directory. It reads the POM, gets the needed configuration information, then executes the goal.
项目对象模型或 POM 是 Maven 中的基本工作单元。它是一个 XML 文件，其中包含有关 Maven 用于构建项目的项目和配置详细信息的信息。它包含大多数项目的默认值。这方面的例子是构建目录，它是目标；源目录，即 src/main/java；测试源目录，即 src/main/test；等等。
POM 从 Maven 1 中的 project.xml 重命名为 Maven 2 中的 pom.xml。不再有包含可以执行的目标的 maven.xml 文件，现在在 pom.xml 中配置目标或插件。执行任务或目标时，Maven 会在当前目录中查找 POM。它读取 POM，获取所需的配置信息，然后执行目标。
