我正在使用 maven-sql-plugin 编写测试类，在这里我设置了用户名、密码、驱动程序名、源文件位置和 url，我还在GRANT插件中添加了查询，但仍然ACCESS-DENIED出现错误。

这是我的插件

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>sql-maven-plugin</artifactId>
<version>1.5</version>

<executions>
 <execution>
  <id>create-database</id>
  <phase>pre-integration-test</phase>
  <goals>
   <goal>execute</goal>
  </goals>
  <configuration>
   <driver>org.h2.Driver</driver>
   <!--<driver>com.mysql.jdbc.Driver</driver> -->
   <url>jdbc:h2:file:target/db/employee;DB_CLOSE_DELAY=-1;DATABASE_TO_UPPER=false;FILE_LOCK=NO;INIT=CREATE
    SCHEMA IF NOT EXISTS employee\;SET SCHEMA
    employee</url>
   <username>root</username>
   <password>root</password>
   <srcFiles>
    <srcFile>src/test/resources/employee.sql</srcFile>
   </srcFiles>
   <sqlCommand>${GRANT ALL PRIVILEGES ON . TO 'root'@'localhost' IDENTIFIED BY 'root' WITH GRANT OPTION}</sqlCommand>
  </configuration>
 </execution>
</executions>
<dependencies>
 <dependency>
  <groupId>com.h2database</groupId>
  <artifactId>h2</artifactId>
  <version>1.3.166</version>
 </dependency>
 <!--<dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> 
  <version>5.1.18</version> </dependency> -->
</dependencies>

我收到以下异常
