问题
I have created maven multi-module project, one child is spring boot-2.1.8.RELEASE & another Angular 8. Created a war file from both spring boot and angular. Created 'manifest.yml' file in parent project, pushed war file to pivotal cloud foundry. Getting ClassNotFoundException org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer.
Below are the logs:

Please check and let me know any configuration file required to debug. Java build pack v3.9 is configured in company's cloud foundry, this build pack has tomcat v8. I am not sure where this class is getting loaded. Spring boot 2 does not have this file. Does anyone had a similar issue? Updating maven dependencies:

I did more research and found out, EmbeddedServletContainerCustomizer does not exist in spring-boot2, it exists in spring boot-1.5 and prior versions.Analyzing more on java-buildpack-container customizer, when it invokes container customizer to customize tomcat container, suppose if there are any server properties configured in application.properties, then?
