方式1：**dependency 本地jar包** （用本方法成功解决）

<dependency>
          <groupId>com.dahua</groupId>
          <artifactId>jna</artifactId>
          <version>1.0</version>
          <scope>system</scope> 
          <systemPath>${
        basedir}/libs/jna.jar</systemPath> 
     </dependency>

方式2：**编译阶段指定外部lib**

<plugin>
     <artifactId>maven-compiler-plugin</artifactId>
     <version>2.3.2</version>
     <configuration>
     <source>1.8</source>
     <target>1.8</target>
     <encoding>UTF-8</encoding>
     <compilerArguments>
     <extdirs>lib</extdirs>
     </compilerArguments>
     </configuration>
     </plugin>

方式3：**将外部jar打入本地maven仓库**  
cmd 进入jar包所在路径，执行以下命令

mvn install:install-file -Dfile=cloud.jar -DgroupId=com.hope.cloud -DartifactId=cloud -Dversion=1.0 -Dpackaging=jar

引入依赖

<dependency>
        <groupId>com.hope.cloud</groupId>
        <artifactId>cloud</artifactId>
        <version>1.0</version>
      </dependency>
