如何在项目上下文之外包含maven模块？ [英] How to include a maven module outside of the project context?

问题描述

我想在某种全局项目目录中有一个模块，这样我就可以在使用该公共代码的所有其他项目中包含该模块。

I'd like to have a module in some kind of global project directory, so that I can include that module in all other projects that use that common code.

但是，我怎么能告诉maven父 pom 来包含和编译这个全局共享模块？
以下不起作用：

But how can I then tell a maven parent pom to include and compile this global shared module? The following does not work:

svn/MyGlobalProject/project-commons/pom.xml           //should be shared among different projects
svn/MyProject/web-parent/trunk/pom.xml                //the parent pom used to build the application
svn/MyProject/web-parent/trunk/project-domain/pom.xml //submodule 1
svn/MyProject/web-parent/trunk/project-web/pom.xml    //submodule 2

父pom.xml：

<project>
        <groupId>de.project</groupId>
    <artifactId>project-parent</artifactId>
    <packaging>pom</packaging>

    <modules>
        <module>project-domain</module>
        <module>project-web</module>
        <module>../project-commons</module> <!-- Error -->
    </modules>
</project>

mvn package 结果：

Child module trunk\project-commons of trunk\pom.xml does not exist

推荐答案

如果您在该全球项目上运行 mvn install ，它将安装在您的本地存储库中。您的其他项目可以将其作为依赖项引用：

If you run mvn install on that global project, it will be installed in your local repository. Your other projects can then reference it as a dependency:

<dependency>
  <groupId>whatever</groupId>
  <artifactId>project-commons</artifactId>
  <version>1.0</version>
</dependency>

这种简单方法的缺点是你的其他项目在你检查之后才会编译 - out project-commons 并运行 mvn install 。

The downside of this simplistic approach is that your other projects won't compile until you've checked-out project-commons and run mvn install.

更高级的方法是部署一个可通过网络访问的存储库（例如 Artifactory 或Nexus）可以部署全局工件。 Artifactory有一个免费的社区版本。然后，您可以在设置文件中列出此存储库，Maven将解析上传到它的工件。

A more advanced approach is to deploy a network-accessible repository (such as Artifactory or Nexus) which you can deploy global artifacts to. Artifactory has a community edition which is free. You can then list this repository in your settings file and Maven will resolve artifacts that are uploaded to it.
