Starting multiple Spring Boot apps from Maven

Question

To do a chain test over a several micro services components I want to start multiple microservices (created using Spring Boot) before running the tests.

Root
|
+  microservice A
|
+  microservice B
|
+  microservice C
|
+  integration tests

I tried to run 'spring-boot:start' multiple times in the pre-integration-test phase from the integration test module, but I could not get this working. So I do have two questions:

• Is there a way to start/stop a spring boot jar from another submodule using the spring-boot-maven-plugin?
• Or, is there another way to start multiple components in the pre-integration-test phase?

It took some time, but I got it working using the following plugin settings
