父模块中的程序集插件可以使用“moduleSets”聚合 pom 子级的二进制工件吗？

在多模块项目中：

parent
  |- child1 (packaging:pom)

can parent生成的聚合工件child1?

经过两天多的测试和阅读文档后，我不确定这是否是由于设计、错误或我自己没有发现明显的原因而不可能实现的。

Using:

$mvn --version
Apache Maven 3.0.4 (r1232337; 2012-01-17 09:44:56+0100)
Maven home: /usr/share/maven-bin-3.0
Java version: 1.8.0_66, vendor: Oracle Corporation

Remarks:

• 在以下示例中，将 child1 包装从pom to jar确实按预期工作！
• 当前错误：

[错误] 无法在项目父项目上执行目标 org.apache.maven.plugins:maven- assembly-plugin:2.6:single (build-module): 无法创建程序集: 创建程序集归档包时出错: 您必须至少设置一个文件。 -> [帮助1]

• 我附加了 child1 的 pom 的第二个版本，它也不起作用，其中我设置了 pom 打包模块不可用的所有 jar 打包绑定，也就是说，packaging=pom 或 Packaging=jar 的有效 pom 是相同的。这也行不通！
