如何从一个多模块Maven项目

Question

Ive得到了一个多模块的Maven的设置像下面添加一个依赖，

+- pom.xml 
+- module1/ 
    +- pom.xml 
+- module2/ 
    +- pom.xml 

module2产生一个可执行的JAR与它的依赖复制到lib/目录一起。该pom.xml此含有

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-dependency-plugin</artifactId> 
    <executions> 
     <execution> 
      <id>copy-dependencies</id> 
      <phase>prepare-package</phase> 
      <goals> 
       <goal>copy-dependencies</goal> 
      </goals> 
      <configuration> 
       <outputDirectory>${project.build.directory}/module2/lib</outputDirectory> 
       <overWriteReleases>false</overWriteReleases> 
       <overWriteSnapshots>false</overWriteSnapshots> 
       <overWriteIfNewer>true</overWriteIfNewer> 
       <includeScope>runtime</includeScope> 
      </configuration> 
     </execution> 
    </executions> 
</plugin> 
<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-jar-plugin</artifactId> 
    <configuration> 
     <archive> 
      <manifest> 
       <addClasspath>true</addClasspath> 
       <classpathPrefix>lib/</classpathPrefix> 
       <mainClass>com.test.JksUtility</mainClass> 
      </manifest> 
      <manifestEntries> 
       <Class-Path>.</Class-Path> 
      </manifestEntries> 
     </archive> 
     <outputDirectory>${project.build.directory}/module2</outputDirectory> 
    </configuration> 
</plugin> 

的问题变得明显时module1引用module2作为依赖。在module1的pom.xml包含，

<dependency> 
    <groupId>com.test</groupId> 
    <artifactId>jksutil</artifactId> 
    <version>${jksutil.version}</version> 
</dependency> 

当我尝试运行module1它告诉我，它无法找到的module2任何相关性，因为它要求所有的罐子在.m2库lib/目录下。这是由于上面定义的classpathPrefix。

比如我会得到下面的错误了丢失的依赖，

java.io.FileNotFoundException: /Users/test/.m2/repository/com/test/jksutil/1.2.1-SNAPSHOT/lib/argparse4j-0.7.0.jar (No such file or directory)

反正是有解决这个除了创建脂肪/超级罐子？

请尝试使用Maven Shade Plugin构建可执行文件jar https://maven.apache.org/plugins/maven-shade-plugin/index.html
