Why mvn spring-boot:run fail to find some ojdbc8 related jars?

Question

My pom.xml has ojdbc8 dependency and it pull in other dependencies like ucp, oraclepki, osdt_core, ...

When I package my project and run it as a executable jar, everything is fine! But I got FileNotFoundException about these jars when I run my project using "mvn spring-boot:run". Why and how can I get rid of this problem?

EDIT

The project is a web project using JSP. But other projects which use Thymeleaf don't have this issue and I don't know why...

Not only this one but also 4 other jars were reported:
Failed to scan [file:/D:/Lib/com/oracle/ojdbc/oraclepki/19.3.0.0/osdt_core.jar]
Failed to scan [file:/D:/Lib/com/oracle/ojdbc/oraclepki/19.3.0.0/osdt_cert.jar]

When I do mvn package, I think it is a fat jar and also an executable jar. But my question is about using "mvn spring-boot:run" which doesn't related to JAR packaging. — Magic, Jun 28 '20 at 06:26
as far as I understood, this is not an actual problem - these are warnings and they are shown because embedded tomcat searches for some (optional) dependencies that ojdbc8 references - there is a way to turn this auto scanning off in a separate tomcat instance, but you have to do more tweaks to turn this off in embedded tomcat. see https://stackoverflow.com/questions/45460750/tomcat-cannot-find-gdk-custom-jar-oracle-cannot-create-it — hello_earth, Feb 18 '21 at 08:42

Edit the context.xml file for Apache Tomcat, and add an entry like the following one to set the value of scanClassPath to false: <JarScanner scanClassPath="false" />

Spring boot has a property to disable tomcat's jar scanning as needed. In your case you would need this:

server.tomcat.additional-tld-skip-patterns=oraclepki.jar, osdt_core.jar, osdt_cert.jar

or in yaml:

server.tomcat.additional-tld-skip-patterns:
  - oraclepki.jar
  - osdt_core.jar
  - osdt_cert.jar

It also allows basic pattern matching if that's more your style.

See: https://docs.spring.io/spring-boot/docs/current/reference/html/application-properties.html#application-properties.server.server.tomcat.additional-tld-skip-patterns

Why mvn spring-boot:run fail to find some ojdbc8 related jars?
