使用Maven在單獨的jar中構建和打包應用程序和依賴關係

Question

我在尋找一個pom.xml配置，它將我的應用程序打包到一個jar文件中，並將所有應用程序依賴關係打包到另一個jar文件中。我看着Maven的組裝插件，並具有以下配置我是能夠建立一個應用程序罐子，然後用所有依賴的應用程序的jar，但我需要依賴罐子不包含我的應用程序：

<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> 

謝謝

我已經看到通過在模塊中構建應用程序解決了這個問題。這裏有一個很好的博客：http://giallone.blogspot.com/2012/12/maven-install-missing-offline.html?_sm_au_=iVVnK0HqJZDtb1Hw

對於你的情況，你可以有一個名爲'dependencies'的模塊，它使用maven-dependency-plugin和maven-assembly-plugin來複制所有依賴並將它們打包罐。然後，您的應用程序可以引用該jar，因爲它依賴於單獨的模塊。頂層將構建兩者。
