创建程序集归档文件箱时出错：您必须至少设置一个文件 [英] Error creating assembly archive bin: You must set at least one file

问题描述

我有一个maven多模块项目，其中包含一个名为 mod1 的模块，我正在尝试将其添加到文件夹 / project jars ，带有 mvn assembly：assembly 来自应用程序文件夹，其中app是pom.xml。

I have a maven multi-module project with a module called mod1 that I'm trying to add into a folder /project jars with mvn assembly:assembly from the app folder, where the app pom.xml is.

错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.3:single (assembly) on project wrapper: Failed to create assembly
: Error creating assembly archive bin: You must set at least one file. -> [Help 1]

项目文件夹结构：

app
    | pom.xml
    | src    | main     | ...
wrapper
    | pom.xml
    | src    | main     | ...
mod1
    | pom.xml
    | src    | main     | ...

// After mvn assembly:assembly

project jars
    | mod1.jar

更新

app pom.xml

app pom.xml

<project>
  <groupId>org.test</groupId>
  <artifactId>app</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>pom</packaging>

  <modules>
    <module>../mod1</module>
    <module>../wrapper</module>
  </modules>
</project>

推荐答案

为什么要在项目'app'中声明两者模块'包装'和'mod1'。 app必须在依赖库中使用'mod1'吗？

Why you declare in the project 'app' the both modules 'wrapper' and 'mod1'. app must use 'mod1' at dependency lib?

执行此操作：

Add parent pom.xml and 3 modules :
    +app
    +wrapper
    +mod1

pom app：

<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>

使用< includes> 和<排除> 。

要创建程序集，请使用以下答案：
Maven构建具有依赖关系的程序集

To create the assembly, use this answer : Maven build assembly with dependencies
