如何强制maven安装在依赖项目上？ [英] how to force maven install on dependent project?

问题描述

我有项目B依赖于项目A.

在项目B的pom.xml文件中，我已经声明了一个依赖关系：

 <依赖关系> 
< groupId>< / groupId> 
< artifactId> A< / artifact> 
< version> 1< / version> 
< scope> compile< / scope> 
< / dependency> 
  

但是，每次对项目A进行任何更改，我必须在eclipse上运行maven install将项目安装到我的用户资料库。

如何在项目B构建并运行之前确保项目A已经建成并安装？

解决方案

使用包装= pom的模块来控制整个构建。在另一个Eclipse项目中，称之为顶级，具有这个pom：

 < 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/xsd/maven-4.0.0.xsd\"> 
< modelVersion> 4.0.0< / modelVersion> 
 
< groupId>< / groupId> 
< artifactId>顶层< / artifactId> 
< version> 1< / version> 
< packaging> pom< / packaging> 
 
< modules> 
< module> ../ A< / module> 
< module> ../ B< / module> 
< / modules> 
< / project> 
  

然后在这个pom上执行你的maven操作（清洁，安装等）。 Maven将找出处理模块的正确顺序。

一个警告词：Maven使用文件系统来访问A和B的相对pom位置。如果所有三个项目都在相同的根目录（Eclipse工作空间根，git repo根目录等）下，则可以工作。

I have project B which depends on project A.

On project B's pom.xml file, I have declared A dependency as:

<dependency>
   <groupId></groupId>
   <artifactId>A</artifact>
   <version>1</version>
   <scope>compile</scope>
</dependency>

But every time I make any changes on project A, I have to run maven install on eclipse, to install the project to my user's repository.

How can I make sure project A is built and installed before project B is built and ran?

解决方案

Use a module with packaging=pom to control the entire build. In another Eclipse project, call it top-level, have this pom:

<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/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId></groupId>
    <artifactId>top-level</artifactId>
    <version>1</version>
    <packaging>pom</packaging>

    <modules>
        <module>../A</module>
        <module>../B</module>
    </modules>
</project>

Then perform your maven operations (clean, install, etc.) on this pom. Maven will figure out the right order for processing the modules.

One word of warning: Maven uses the file system to access the relative pom locations for A and B. This only works if all three projects are under the same root directory (the Eclipse workspace root, the git repo root directory, etc.)
