Deploying SpringBoot Project to WLS, Dynamic Web Module keeps reverting back to 4.0

Question

I have a springboot project that I am working on. I am using spring boot version 2.1.3. I need this version so that I can use mysql connector version 8.0.15. I am using Hibernate and JPA in this project.

Since WLS 12.1.3 does not use servlet 4.0 I am getting this error

When I deploy my .war file to Web Logic Server I get this error:

Message icon - Error VALIDATION PROBLEMS WERE FOUND C:\Oracle\user_projects\domains\dev_domain\weblogic.utils.classloaders.GenericClassLoader@2ad4423 finder: weblogic.utils.classloaders.CodeGenClassFinder@3be64d51 annotation: \WEB-INF\lib\tomcat-embed-jasper-9.0.16.jar!\META-INF\web-fragment.xml:18:3:18:3: problem: cvc-enumeration-valid: string value '4.0' is not a valid enumeration value for web-app-versionType in namespace http://xmlns.jcp.org/xml/ns/javaee

I have tried going into org.eclipse.wst.common.project.facet.core.xml and setting the dynamic web module in there to 3.1 . However as soon as I update the maven project it reverts back to 4.0.

I have also made changes to my pom file to make sure the right java-x servlet has been used. Here is my pom.xml

Servlet specs 4.0 are part of JEE 8 and is not yet implemented in WebLogic Server 12c. You may use another application server that supports JEE 8 and Servlets 4.0.
