如何使Maven构建依赖项目 [英] how to make maven build dependent project

问题描述

我有一个与其他项目有多个依赖项的项目.

I have project with several dependencies on other project.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>group1</groupId>
<artifactId>artifact1<artifactId>
<name>RealtyRegistry</name>
<packaging>war</packaging>
<version>1.0.0-SNAPSHOT</version>
<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
    <dependency>
        <groupId>group1</groupId>
        <artifactId>artifact2</artifactId>
        <version>1.0.0</version>
    </dependency>
    <dependency>
        <groupId>group1</groupId>
        <artifactId>artifact3</artifactId>
        <version>1.0.0</version>
    </dependency>
</dependencies>

所有这些都是我同时开发的.我将版本添加到所有项目的文件中，并且需要与相关项目一起构建主项目.对于没有树状结构的项目该怎么做?

All of them developed by me simultaniously. I add edition to files of all of project and i need to build main project together with dependent ones. How to do that for projects without tree structure?

对于层级项目，可以有2棵或更多棵覆盖树，例如:A取决于B，C； D取决于C，E； A和D是独立的.

There can be 2 or more covering trees for projects hierachy, for example: A depends on B,C; D depends on C,E; A and D are independent.

推荐答案

您可以使用模块"一起构建多个项目.通常，您可以通过使用<packaging>pom</packaging>创建一个母亲"项目，并使用<modules>标记将您的真实项目添加为模块来完成此操作.然后，当您构建母亲"项目时，所有模块都将以正确的顺序自动构建.

You can build multiple projects together using "Modules". Normally, you would do this by creating a "mother" project with <packaging>pom</packaging> and adding your real project as modules using the <modules> tag. Then, when you build the "mother" project, all modules are automatically built in the right order.

以下是示例行家中的示例本书:

<groupId>org.sonatype.mavenbook.multi</groupId>
<artifactId>simple-parent</artifactId>
<version>1.0</version>
<packaging>pom</packaging>

<modules>
    <module>simple-weather</module>
    <module>simple-webapp</module>
</modules>

请注意，这要求您将模块包含在相应命名的子文件夹中.例如，您将在某个文件夹中放置母亲" pom:

Note that this requires you to have your modules in subfolders that are named accordingly. For example, you would have the "mother" pom in some folder:

/.../my-project/

以及其中的模块:

/.../my-project/simple-weather/
/.../my-project/simple-webapp/
