Can I create a SpringBootApplication in src/test/java?

Question

We want to run some remote tests in Docker. Our idea was to create a SpringBootApplication that will run the tests and report the results and we will have this Application deployed in it's own Docker with it's own JAR.

To make sure that it does not ship with the main code (src/main/java) we want to have this code in src/test/java..

From the documentation this does not appear possible from the Spring-boot-maven-plugin.

So now I am trying to create a test-jar but when I run the Application class I get

Is there any documentation on how to package a SpringBoot Application without the maven plugin?

package as in create the jar? you need some kind of compiler and you should use the default project structure since you don't seem to have any real reason not to. Why is shipping your application tied to your source code in anyway? — Will Evers, Jan 24 '19 at 15:48

It turns out all I needed to do as add a file to my source repo

src/main/resources/META-INF/spring.factories

You can grab a copy from here

All thanks to the answer from another post related the question
