I'm working on a project that uses Ktor and Hibernate. Currently the project can only run using the gradle Shadow plugin. This however breaks hot reloading, since all classes are compiled into a jar file, preventing ktor from picking up changes. If I run without the Shadow plugin, then I get a '<Entity> is not mapped' message from Hibernate. Does anyone have a similar setup where they managed to get the auto reload functionality to work?

You could minimize the impact of having to make a shadow jar by splitting your project in two sub-projects: • a library containing your entities, for which you build a shadow jar, and • a Ktor app that uses the above library and uses hot reloading.

So I managed to get the application running withou shadowJar by adding the following to my build script:
Copy code
sourceSets {

	java {
		main {


The only issue now is that auto-reload doesn't quite seem to work. If I update a log to an endpoint, while a 'gradle build' process is running alongside my 'gradle run' process, I see
Copy code
ktor.application Changes in application detected.
ktor.application Responding at <>
But when I hit the endpoint, the log message isn't updated 😕
