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

A note to anyone that runs into this when using v9.0.0 or greater of the Shadow Jar plugin. You have to set:
duplicatesStrategy = DuplicatesStrategy.INCLUDE
In addition to mergeServiceFiles(). Release notes. Hopefully this saves people some time!
