一零五八、Failed to execute goal org.codehaus.mojo:exec-maven-plugin:3.1.0:exec (default-cli) on project

解决:Failed to execute goal org.codehaus.mojo:exec-maven-plugin:3.0.0:exec (default-cli) on project spring_aop: Command execution failed.的问题

在pom中加入以下依赖插件，内容不用更改

maven-compiler-plugin：用来编译Java文件，指定JDK版本等（我试着换成1.8.0 ，好像不行然后又改成1.6.0了）
exec-maven-plugin：用来执行class文件，其中插件配置中需指明执行类的路径。

<build>
     <plugins>
         <plugin>
             <groupId>org.codehaus.mojo</groupId>
             <artifactId>exec-maven-plugin</artifactId>
             <version>1.6.0</version>
             <executions>
                 <execution>
                     <goals>
                         <goal>java</goal>
                     </goals>
                 </execution>
             </executions>
             <configuration>
                 <classpathScope>test</classpathScope>
             </configuration>
         </plugin>
     </plugins>
</build>

补充：
使用mybatis-plus自动生成框架
