Failed to load driver class oracle.jdbc.OracleDriver in either of HikariConfig class loader or Thread context - spring

Question

I'm working with Spring for the first time and trying to set it up so that my code can access an Oracle database. I have the following configuration in my application.properties:
spring.datasource.url=jdbc:oracle:thin:#140.192.30.237:1521:def
spring.datasource.username=<username>
spring.datasource.password=<password>
spring.datasource.driver.class-name=oracle.jdbc.driver.OracleDriver
My pom.xml contains the following dependencies:
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>

</dependency>
<dependency>
<groupId>javax.json</groupId>
<artifactId>javax.json-api</artifactId>
<version>1.0</version>
</dependency>
</dependencies>
Yet I get the following error and am not sure how to solve it, I"ve found similar ones from searching but none that have solved my problem:
Failed to bind properties under '' to com.zaxxer.hikari.HikariDataSource:
Property: driverclassname
Value: oracle.jdbc.OracleDriver
Origin: "driverClassName" from property source "source"
Reason: Failed to load driver class oracle.jdbc.OracleDriver in either of HikariConfig class loader or Thread context classloader
Action:
Update your application's configuration
Thanks for any tips to solve this.

Answer 1

As its mentioned in your error the problem is with your configuration.
Following line,
spring.datasource.driver.class-name=oracle.jdbc.driver.OracleDriver
should change as,
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
Note that its not driver.class-name, instead its driver-class-name

Answer 2

Add below dependency and repository in the pom
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0.3</version>
</dependency>
<repositories>
<repository>
<id>codelds</id>
<url>https://code.lds.org/nexus/content/groups/main-repo</url>
</repository>
</repositories>
Also add the following properties in the application.properties
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:#localhost:1521:xe(SID)
spring.datasource.username=system
spring.datasource.password=pw

Answer 3

Try on the project directory pom.xml file in in command promt or your ide.
mvn clean install

Below dependency to POM should work.
<!-- https://mvnrepository.com/artifact/oracle/ojdbc6 -->
<dependency>
