儘管我們使用了maven進行專案管理，但是很多時候可能需要使用依賴的jar包（排查問題，分發）
我們可以基於maven-dependency-plugin 解決

參考配置

• 核心配置

<plugin>

    <groupId>org.apache.maven.plugins</groupId>

    <artifactId>maven-dependency-plugin</artifactId>

    <configuration>

      <excludeTransitive>false</excludeTransitive>
 

      <stripVersion>false</stripVersion>

      <outputDirectory>./lib</outputDirectory>

    </configuration>

</plugin>

• pom.xml
