IDEA逆向生成工程失败报错：generate failed: Exception getting JDBC Driver

报的错误：
Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.4:generate (default-cli) on project generatorSqlmapCustom: Execution default-cli of goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.4:generate failed: Exception getting JDBC Driver

问题原因：
无法获取到JDBC驱动
解决办法有以下两种，可以分别试下，这里我是用第二种方法解决的：

1. 手动指定generatorConfig.xml的位置
2. pom.xml中把mysql-connector-java依赖添加在generator插件里

pom文件的正确的配置如下：
