I have a multi-module Maven project that contains an application consisting of several Spring Boot services. I am trying to set up integration and end-to-end tests for the services and am using a combination Maven plugins to orchestrate this.
I have one module that is intended to contain only end-to-end tests for groups of collaborating services that perform some work. It contains only test code and resources. I'm using the failsafe plugin (org.apache.maven.plugins:maven-failsafe-plugin) to perform the integration tests, the Spring Boot Maven plugin (org.springframework.boot:spring-boot-maven-plugin) to start and stop the "main" service and the Maven exec plugin (org.codehaus.mojo:exec-maven-plugin) to start the other services that are being used in the end-to-end tests.
I'm running into a problem that appears to be related to the repackage goal of the Spring Boot plugin. The e2e module has nothing that needs to be repackaged, so I want to skip this goal. Shouldn't be too hard, right?
org.springframework.boot
spring-boot-maven-plugin

The problem with this, is that the Maven build fails because it can't find a "main" class to repackage (as an executable jar, I believe). Well, there is no main class for this module.
The more important question is: why is
