Question

有些像Maven: Non-resolvable parent POM但不一样。

我有父母pom

<groupId>group</groupId>
<artifactId>parent</artifactId>
<version>SNAPSHOT</version>
<packaging>pom</packaging>

<modules>
    <module>module1</module>
    <module>module2</module>
    <module>module3</module>
</modules>

module1使用dependencies

定义了一些dependencyManagement

儿童游戏：module3/pom.xml尝试导入module1

<parent>
    <artifactId>group</artifactId>
    <groupId>parent</groupId>
    <version>SNAPSHOT</version>
    <relativePath>../</relativePath>
</parent>

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>group</groupId>
      <artifactId>module1</artifactId>
      <version>SNAPSHOT</version>
      <scope>import</scope>
      <type>pom</type>
      <!--
      <systemPath>../module1</systemPath>
      -->
    </dependency>
  </dependencies>
</dependencyManagement>

如果我尝试构建父级，则可以

mvn validate
[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[INFO] Reactor Build Order:

... ...

[INFO] parent ............................................ SUCCESS [0.128s]
[INFO] module1 ........................................... SUCCESS [0.011s]
[INFO] module2 ........................................... SUCCESS [0.009s]
[INFO] module3 ........................................... SUCCESS [0.009s]
... ...
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS

但是如果我在子模块中运行build，它就会失败

mvn validate
[INFO] Scanning for projects...
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]
[ERROR]   The project group:module3:SNAPSHOT (/path-tp/project/module3/pom.xml) has 5 errors

我尝试了什么

我尝试使用systemPath，import范围不支持。
我尝试将import范围dependencies声明从module3移到父模块，但它没有抱怨循环依赖

如何构建/加载单独的子模块module3，还是有其他方法可以将大量的dependencyManagement拆分为多个子模块？

Answer 1

在父级别工作时，Maven能够解决模块之间的依赖关系。

但是如果你在模块3中工作，它不知道module1是项目的兄弟模块。

如果您想直接在模块3内部工作，则需要先安装模块1。
