When setting EmbeddedServletContainerFactory with camunda spring boot ProcessEngine bean goes missing

问题

when I add the following bean to my Spring boot with camunda process engine (using camunda-bpm-spring-boot-starter):

    @Bean
public EmbeddedServletContainerFactory servletContainerFactory() {
    return new TomcatEmbeddedServletContainerFactory() {

        @Override
        protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
                Tomcat tomcat) {

I get the following:

 Spring-Boot:  (v1.4.3.RELEASE)
  Camunda BPM: (v7.6.0)
  Camunda BPM Spring Boot Starter: (v2.0.0)

Description:

Field processEngine in au.com.nukon.ManufacturingApplication required a bean of type 'org.camunda.bpm.engine.ProcessEngine' that could not be found.


Action:

Consider defining a bean of type 'org.camunda.bpm.engine.ProcessEngine' in your configuration.

Any Ideas? my objective is to be able to add an additional war webapp to my application.
