java spring boot - war file is not deploying on Apache Tomcat - spring-boot

Question

I am deploying war file on apache tomcat 7 but it is not deploying,
it shows error which I do not understand.
I have tried to remove all jar files from the .m2 folder and rebuilded the application but the error is still there:
SEVERE: Unable to process Jar entry [META-INF/versions/9/module-info.class] from Jar [jar:file:/D:/Dipen/apache/bin/webapps/Graspgame-0.0.1-SNAPSHOT/WEB-INF/lib/log4j-api-2.11.2.jar!/] for annotations

Spring Boot 2.1.x requires a Servlet 3.1 or later container. Tomcat 7 is a Servlet 3.0 container so it won't work. If you want to use Tomcat, you'll need to use 8.5 (Servlet 3.1) or 9.0 (Servlet 4.0).
