oracle mybatis generator java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

Question

I'm trying to establish a SSM project with oracle in IDEA. I'm new to oracle and I have problems using MyBatis generator to generate tables from oracle.
I can use SQL to get data from my database but when I try to generate it I got errors java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

Here's my errors:

Here's my code

<?xml version="1.0" encoding="UTF-8"?>

        </javaModelGenerator>

        <sqlMapGenerator targetPackage="mappers"
                         targetProject=".\resource">

        </sqlMapGenerator>
  
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.yulan.dao"

        </javaClientGenerator>

        <table tableName="CUSTOMER" domainObjectName="Customer"></table>
    </context>
</generatorConfiguration>

Here's my pom.xml:

and here's my maven denpendency:

Can anyone tell me why? Thanks.

You will need to make the Oracle driver a dependency of the generator, not your project in general. You can see an example of that here: https://github.com/mybatis/generator/blob/master/core/mybatis-generator-systests-mybatis3-java8/pom.xml#L48-L79
