IntelliJ IDEA not copying resources on build

Impulse The Fox :

My build output is out/production/classes. Java files get compiled into classes just fine and get put on out/production/classes/[packageName], but resources aren't copied. As far as I know they should go directly inside the out/production/classes directory.

If relevant, I'm using Java 11, Spring Boot and Gradle. This is my build.gradle

plugins {
    id 'org.springframework.boot' version '2.1.3.RELEASE'
    id 'java'
}

apply plugin: 'io.spring.dependency-management'

group = 'net.impfox'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
}

dependencies {
    // hidden
}

And my Compiler settings:

What could be the cause for my resources not being copied to the output directory and how can I fix this?

Impulse The Fox :

I was not able to find the root problem, but I've got a guess. I renamed the entire project before and replaced every occurence of the old project name with the new one. Maybe some internal cache still had the old name inside?

I ended up cloning the project from version control, now it works.
