maven程序集插件模块集源指令不包括任何文件，也不匹配包含的模块 [英] The maven assembly plugin moduleset sources instructions are not including any files and not matching the included modules

问题描述

我有一个多模块maven项目，我正在尝试使程序集插件的模块集源部分工作。

I have a multi-module maven project, and I'm trying to get the moduleset sources portion of the assembly plugin to work.

我有模块 module_parent ， module_a 和 module_assembly 。

module_a 和 module_assembly 是 module_parent 的子项。

module_assembly 在 module_a 上声明了pom依赖。

module_assembly has a declared pom dependency on module_a.

module_assmebly 具有程序集插件，其assembly.xml类似于：

module_assmebly has the assembly plugin, with the assembly.xml looking like:

<?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_assembly有明确的依赖关系。 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>

我打开调试时从mvn包获得的错误是：

The error I get from mvn package with debug turned on is:

[DEBUG] All known ContainerDescritporHandler components: [metaInf-services, plexus, metaInf-spring, file-aggregator]
[DEBUG] No dependency sets specified.

我认为主要问题是这条警告线：

I think the main problem is this warning line:

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

如何更正？

推荐答案

如果module_assembly没有对模块的子引用，它不算作模块。请注意，此处的内容仅指儿童： http： //maven.apache.org/plugins/maven-assembly-plugin/advanced-module-set-topics.html

If module_assembly doesn't have a child reference to your module, it's not counted as a module. Note the content here refers to children only: 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。

If you want to do this, you need to use a dependencySet rather than a moduleSet.
