spring boot app shutting down without error

Question

I am running a spring boot application with mysql, web, jpa as dependencies. I have configured the application.properties file with the database properties. The log is attached for more details below:

I have created the git repository and uploaded my code onto Github - Link to Github repo

I am also attaching the pom.xml for reference

How should I be debugging this error. Kindly let me know as there is lot of magic going on here.

@zilcuanu run this as maven project with spring-boot:run as the goal. — Pramod

The condition evaluation report in the application log shows that the embedded servlet container hasn't been configured as javax.servlet.ServletRequest is not on the classpath:

ServletWebServerFactoryAutoConfiguration:
  Did not match:
     - @ConditionalOnClass did not find required class 'javax.servlet.ServletRequest' (OnClassCondition)

It should be on the classpath as you have a dependency on spring-boot-starter-web which pulls in tomcat-embed-core that contains all of the Servlet API classes. The application log also shows that C:\Users\classpath\.m2\repository\org\apache\tomcat\embed\tomcat-embed-core\8.5.32\tomcat-embed-core-8.5.32.jar is on the classpath.

For the jar file to be on the classpath and a class that it contains not to be found, the jar file must be corrupted. This can happen when Maven downloads the jar. Try deleting the C:\Users\classpath\.m2\repository\org\apache\tomcat\embed\tomcat-embed-core\8.5.32\ directory and rebuilding your application. This will cause Maven to download a new copy of the jar and, hopefully, to not corrupt it this time.

Finally, I was able to solve this problem. I deleted the repository directory inside .m2 and build the whole project once again. This time, it worked.
