Hello, I want to deploy my Ktor App to Heroku. The deployment says “Build successful” but when I start the app, I get application error.
Now I saw that I don’t have a .build/install directory in my build folder.
This direcotry is referenced in the .Procfile as direction for heroku where to start the app.

So how can I create this install directory? Thanks a lot!

Are you following this: https://ktor.io/docs/heroku.html?

Seeing from your screenshot that you are using Gradle and assuming you are using the application plugin, you would call the installDist task, or rather depend on it from the stage task that Heroku is calling.

The critical bit will be adding this to `build.gradle.kts`:

tasks {
    create("stage").dependsOn("installDist")
}

Heroku will check out your code and run gradle stage when you push to heroku, and that will create the build/.build/install build/install directory on Heroku's side. You should not commit build or anything in it to source control.

build/install/ actually
And you should never use tasks.create but always tasks.register due to task configuration avoidance, those instructions are simply bad.

D'oh, yes, missed that it was running a command...
