Maven 程序集插件模块集源指令不包含任何文件并且与包含的模块不匹配

我有一个多模块 Maven 项目，我正在尝试让程序集插件的模块集源部分正常工作。

我有模块“模块父模块", "module_a", and "模块组件".

module_a and 模块组件是的孩子模块父模块.

模块组件已声明 pom 依赖项module_a.

模块组装有程序集插件，程序集.xml 如下所示：

<?xml version="1.0"?>
<assembly>
  <id>bin</id>
  <formats>
    <format>zip</format>
  </formats>
  <includeBaseDirectory>false</includeBaseDirectory>
  <moduleSets>
    <moduleSet>
      <useAllReactorProjects>true</useAllReactorProjects>
      <includes>
        <include>com.mystuff:module_a</include>
      </includes>
      <sources>
        <fileSets>
          <fileSet>
            <outputDirectory>/</outputDirectory>
            <excludes>
              <exclude>**/target/**</exclude>
            </excludes>
            <directory>/</directory>
          </fileSet>
        </fileSets>
      </sources>
    </moduleSet>
  </moduleSets>
</assembly> <!-- -->

我对 module_a 的 module_assemble 有显式依赖。 module_ assembly 的 pom 中的依赖关系如下所示：

<dependencies>
    <dependency>
        <groupId>com.mystuff</groupId>
        <artifactId>module_a</artifactId>
        <version>1.0</version>
        <type>pom</type>
    </dependency>
</dependencies>

我从打开调试的 mvn package 得到的错误是：

[DEBUG] All known ContainerDescritporHandler components: [metaInf-services, plexus, metaInf-spring, file-aggregator]
[DEBUG] No dependency sets specified.
[WARNING] The following patterns were never triggered in this artifact inclusion filter:

我认为主要问题是这条警告线：

[WARNING] The following patterns were never triggered in this artifact inclusion filter:
    o  'com.mystuff:module_a'

我该如何纠正这个问题？

如果 module_ assembly 没有对您的模块的子引用，则它不被视为模块。请注意，此处的内容仅适用于儿童：http://maven.apache.org/plugins/maven-assemble-plugin/advanced-module-set-topics.html http://maven.apache.org/plugins/maven-assembly-plugin/advanced-module-set-topics.html

如果你想这样做，你需要使用 dependencySet 而不是 moduleSet。
