请问老师，我用的数据库为mysql-5.7.27, 现在用的驱动是mysql-connector-java-5.1.25.jar 但总是提示 Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.7:generate (default-cli) on project mmall: Execution default-cli of goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.7:generate failed: Exception getting JDBC Driver: ${db.driverClassName} -> [Help 1]

  pom的配置
  <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.25</version>
      </dependency>
  
  datasource.properties的配置
  db.driverLocation=D:/maven/apache-maven-3.6.1/repository/mysql/mysql-connector-java/5.1.25/mysql-connector-java-5.1.25.jar
  db.driverClassname=com.mysql.jdbc.Driver
  db.url=jdbc:mysql://127.0.0.1:3306/shopping_mall?characterEncoding=utf-8
  db.username=root
  db.password=root
