如何将maven依赖项打进jar包，将一个完整的项目打进jar包

目的：我的目的就是将项目所有的文件，包括pom文件中依赖的jar包都打进一个jar包里面。

过程：将下面的内容放到pom文件里面。

</dependencies>
<build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>com.allen.capturewebdata.Main</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
</build>

执行：

输入打包命令：mvn assembly:assembly

或者按照下面的方式：

完整的pom
