The cat-boot-structurizr-sample from catalysts

Unsuccessful in getting up and running with your sample

I really liked the idea of doing the dsl work in Kotlin and taking advantage of some of the nice features of Spring Boot, but I ran into two problems that I was ultimately unable to figure out. :/

The first was how to add a configuration parameters file such that I could read in certain values from it.
Went down a rat-hole of how to get it properly defined and annotated, and for a while I did have it successfully working, but then suddenly it started complaining that the configuration class may not be final. I don't know if it finally picked up a change from Kotlin 1.2.50 to 1.2.60 or something else.

The other problem was that I really needed to take advantage of the structurizr component finders (namely the spring-component-finder to start with). When I was able to run the app using that finder, it spewed out tons of errors saying "A component type must be provided.". Right as I tried to get set up to debug that, the build stopped working and I had to give up.

If there is any chance you guys might add to this demo showing how to use a config property file and how to use a component scanner, it would be really great.

Greetings!
I am trying to run your example with this dependencies versions:

dependencies {
    compile 'cc.catalysts.boot:cat-boot-structurizr:0.2.24'
    compile "org.springframework.boot:spring-boot-starter:2.0.1.RELEASE"
}

The following error occurs:
