從多個maven模塊構建可執行jar

Question

我有從多個maven模塊構建單個可執行jar的問題。 所以這裏的情況：我有三個maven模塊：應用程序 - >持久性 - >域。我也有父pom.xml。我加入到這一父POM行家組件插件：

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-assembly-plugin</artifactId> 
    <configuration> 
     <archive> 
      <manifest> 
       <mainClass>com.toys.app.Service</mainClass> 
      </manifest> 
     </archive> 
     <descriptorRefs> 
      <descriptorRef>jar-with-dependencies</descriptorRef> 
     </descriptorRefs> 
    </configuration> 
</plugin> 

因此，當我從命令行在父POM目錄（其含有parent.pom和應用程式，持久性和域行家模塊）類型的命令：MVN組件：組件 它給了我一個錯誤：

每隔Maven的生命週期正常工作！誰能幫我？

Answer 1

嘗試添加執行階段：

 <plugin> 
      <artifactId>maven-assembly-plugin</artifactId> 
      <configuration> 
       <archive> 
        <manifest> 
        <mainClass>com.toys.app.Service</mainClass> 
        </manifest> 
       </archive>    
       <descriptorRef>jar-with-dependencies</descriptorRef>     
      </configuration> 
      <executions> 
       <execution> 
        <id>make-jar-with-dependencies</id> 
        <phase>package</phase> 
        <goals> 
         <goal>single</goal> 
        </goals> 
       </execution> 
      </executions> 
     </plugin> 
    </plugins>

我建議你添加在同一水平上爲您的應用程序，持久性，領域工程項目「分配」。

<project> 

    <artifactId>distribution</artifactId> 
    <packaging>pom</packaging> 

    <parent> 
    ... 
    </parent> 

    <dependencies> 
    <dependency> 
     <groupId>${project.groupId}</groupId> 
     <artifactId>app</artifactId> 
     <version>${project.version}</version> 
     <scope>runtime</scope> 
    </dependency> 
    <dependency> 
     <groupId>${project.groupId}</groupId> 
     <artifactId>persistence</artifactId> 
     <version>${project.version}</version> 
     <scope>runtime</scope> 
    </dependency> 
    <dependency> 
     <groupId>${project.groupId}</groupId> 
     <artifactId>domain</artifactId> 
     <version>${project.version}</version> 
     <scope>runtime</scope> 
    </dependency> 
    </dependencies> 

    <build> 
    <plugins> 
     <plugin> 
     <groupId>org.apache.maven.plugins</groupId> 
     <artifactId>maven-assembly-plugin</artifactId> 
      <configuration> 
      <archive> 
       <manifest> 
       <mainClass>com.toys.app.Service</mainClass> 
       </manifest> 
      </archive>    
      <descriptorRef>jar-with-dependencies</descriptorRef>     
      </configuration> 
      <executions> 
      <execution> 
       <id>make-jar-with-dependencies</id> 
       <phase>package</phase> 
       <goals> 
       <goal>single</goal> 
       </goals> 
      </execution> 
      </executions> 
     <plugin> 
    </plugins> 
    </build> 

</project> 

我在嘗試在移動到自己的項目後創建分佈在反應器POM中時遇到了類似的問題 - 沒有頭痛。

此外，不要忘記添加'分配'模塊到反應堆項目。
