Don't let the shadow jar plugin shadow your application

In my previous post, I shared a template for deploying a ktor application to Google App Engine.

As part of this process I was using the Shadow plugin.
Well it turns out, by default the plugin won't copy service files from java Serviceloader.

This lead to my application failing due SPI classes not being loaded. So if your app breaks by using the plugin just add this to your build.gradle

shadowJar {
    mergeServiceFiles()
}

Happy coding
