Spring boot autoconfigure application start fails

Question

I've built my own starter and the autoconfigure step fails with dependency conflict.

These are the spring boot versions both my starter and upstream project are using

'spring-boot-gradle-plugin', version2.1.8.RELEASE

'spring-boot-autoconfigure', version: '2.4.1'

The following method did not exist:
    'org.springframework.web.servlet.config.annotation.ResourceHandlerRegistration org.springframework.web.servlet.config.annotation.Re
sourceHandlerRegistration.addResourceLocations(org.springframework.core.io.Resource[])'
The method's class, org.springframework.web.servlet.config.annotation.ResourceHandlerRegistration, is available from the following loca
tions:

From your log I see one of two possible problems:

Somewhere you override spring-webmvc-5.3.2 to a higher or lower version
Problem in your starter code (if it configure your WebMvc)

Try mvn dependency:tree or gradle dependencies to explore dependencies. Attached your starter code.
