未能在maven中構建多個程序集。找不到裝配描述符

Question

使用裝配插件時，在嘗試從Maven項目生成兩個或多個罐子時遇到了一些麻煩。

我有以下maven pom.xml文件（見下文）。

然而，當我運行mvn clean compile assembly:single，

我得到以下錯誤： Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.2-beta-5:single (default-cli) on project hyuga: Error reading assemblies: No assembly descriptors found. -> [Help 1]

我缺少什麼？

<plugin> 
    <artifactId>maven-assembly-plugin</artifactId> 
    <executions> 
     <execution> 
      <id>dg2cep</id> 
      <configuration> 
       <archive> 
        <manifest>

啊..你正在執行它，像這樣：mvn ... assembly:single？如果不這樣做，請在生命週期內使用它，如mvn clean package ....
