Answer 1

的maven-assembly-plugin的descriptors屬性預計從開始的一條路徑項目的基礎目錄。例如，如果文件位於src/assembly/distribution.xml之內，則這是您應該指定的路徑。

您在插件綁定的階段也存在問題。階段assembly不存在，您應該使用<phase>package</phase>來代替。

作爲一個副節點，您使用的是插件的舊版本（2.2-beta-5）。請考慮使用最新版本，即2.6。

示例配置：

<plugin> 
    <!-- no need to specify the groupId, it defaults to "org.apache.maven.plugins" --> 
    <artifactId>maven-assembly-plugin</artifactId> 
    <version>2.6</version> <!-- explicit version is safer for build consistency than implicit --> 
    <executions> 
     <execution> 
      <id>make-assembly</id> 
      <phase>package</phase> <!-- bind the execution to the "package" phase --> 
      <goals> 
       <goal>single</goal> 
      </goals> 
      <configuration> 
       <descriptors> 
        <descriptor>src/assembly/distribution.xml</descriptor> <!-- use the path to the file starting from base directory --> 
       </descriptors> 
      </configuration> 
     </execution> 
    </executions> 
</plugin> 

與mvn clean install運行Maven將在包裝階段正確地調用插件。
