Why you declare in the project 'app' the both modules 'wrapper' and 'mod1'. app must use 'mod1' at dependency lib?
为什么你在项目“app”中声明了两个模块“wrapper”和“mod1”。应用程序必须在依赖项库中使用“mod1”？
Do this :
做这个 ：
Add parent pom.xml and 3 modules :
+app
+wrapper
+mod1
pom app :
pom 应用程序：
<dependency>
<groupId>${groupId}</groupId>
<artifactId>mod1</artifactId>
</dependency>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>project/</classpathPrefix>
</manifest>
</archive>
</configuration>
</plugin>
Create assembly.xml and filter dependency with <includes>and <excludes>.
创建assembly.xml与过滤器的依赖<includes>和<excludes>。
To create the assembly, use this answer : Maven build assembly with dependencies
要创建程序集，请使用以下答案： Maven build assembly with dependencies

Check your project structure. In my case the name of the directory that I was referencing with variables ($) was not correct,the directories were called differently and produced this error. I had to follow the error from the parent pom, going through the child, and config.xml.
检查您的项目结构。在我的情况下，我使用变量 ($) 引用的目录名称不正确，目录的调用方式不同并产生了此错误。我必须遵循来自父 pom 的错误，通过孩子和 config.xml。
