No plugin found for prefix ‘mybatis-generator‘ in the current project and in the plugin groups

wrong description:

Use MyBatis Generator to automatically generate mappings when given
No plugin found for prefix 'mybatis- generator' in the current project and in the plugin groups
not found in the current project group and plug the prefix 'mybatisi -generator' plug-ins

wrong reason

Because the mybatis-generator plugin is not imported in pom.xml

Solution

Add the mybatis-generator plugin in the <plugins> tag

		<!--	mybatis-generator插件 用于自动生成javabean和sql
            	version版本要与对应依赖版本一致
        -->
        <plugin>
          <groupId>org.mybatis.generator</groupId>
          <artifactId>mybatis-generator-maven-plugin</artifactId>
          <version>1.3.4</version>
          <dependencies>
            <dependency>
              <groupId>mysql</groupId>
              <artifactId>mysql-connector-java</artifactId>
              <version>5.1.38</version>
            </dependency>
          </dependencies>
          <configuration>
            <overwrite>true</overwrite>
            <configurationFile>./mybatis-generator.xml</configurationFile>
          </configuration>
        </plugin>

The version must be consistent:
this is my dependent version (to be consistent)
