使用Maven在单独的jar中构建和打包应用程序和依赖关系

Question

我在寻找一个pom.xml配置，它将我的应用程序打包到一个jar文件中，并将所有应用程序依赖关系打包到另一个jar文件中。我看着Maven的组装插件，并具有以下配置我是能够建立一个应用程序罐子，然后用所有依赖的应用程序的jar，但我需要依赖罐子不包含我的应用程序：

<plugin> 
    <artifactId>maven-assembly-plugin</artifactId> 
    <version>2.4</version> 
    <configuration> 
     <descriptorRefs> 
      <descriptorRef>jar-with-dependencies</descriptorRef> 
     </descriptorRefs> 
     <finalName>${project.artifactId}-${project.version}</finalName> 
     <appendAssemblyId>false</appendAssemblyId> 
    </configuration> 
    <executions> 
     <execution> 
      <id>jar-with-dependencies</id> 
      <phase>package</phase> 
      <goals> 
       <goal>attached</goal> 
      </goals> 
     </execution> 
    </executions> 
</plugin> 

谢谢

我已经看到通过在模块中构建应用程序解决了这个问题。这里有一个很好的博客：http://giallone.blogspot.com/2012/12/maven-install-missing-offline.html?_sm_au_=iVVnK0HqJZDtb1Hw

对于你的情况，你可以有一个名为'dependencies'的模块，它使用maven-dependency-plugin和maven-assembly-plugin来复制所有依赖并将它们打包罐。然后，您的应用程序可以引用该jar，因为它依赖于单独的模块。顶层将构建两者。

顶层POM

    <packaging>pom</packaging> 
.

    <modules> 
     <module>dependencies</module> 
     <module>yourApp</module> 
    </modules>
