java.sql.SQLException: Unable to load class: oracle.jdbc.driver.OracleDriver from ClassLoader:java.net.URLClassLoader@545b995e;

Question

I am getting below error when I am starting server or triggering pipeline.

java.sql.SQLException: Unable to load class: oracle.jdbc.driver.OracleDriver from ClassLoader:java.net.URLClassLoader@545b995e;

I checked in lib folder of Tomcat and ojdbc jar was also missing

I checked in pom.xml, and dependency was missing, so I put below dependency in pom.xml and triggered a build again.

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc</artifactId>
    <version>8.0</version>
    <scope>provided</scope>
</dependency>

Still, I am getting same issue. Below is the detail log. What could be the possible reason?

If you check in maven repo, does not exists the 8.0 version, the correct version is 19.3.0.0
