Gradle can't resolve my dependencies if not provided in a certain format

Question

I can't pull any dependencies from my Artifactory repository, if they're in a certain format. However maven manages to pull all those dependencies without any problems regardless of the format.

> Could not resolve all files for configuration ':compileClasspath'.
   > Could not find eu.****:cloudnet-bridge:1.0.0.

This is the error I am getting in IntelliJ (2020.1.2 Community Edition) using gradle (6.5).

This is the folder structure for a non-working dependency (the jar is directly placed in the folder)

This is the folder structure for a working dependency (the jar is inside a version folder along with a valid POM; the artifactory auto-generated one does NOT work here! There also is a xml file in the dependency's root folder containing some information about the version etc.)

Now my question is whether or not I can fix this issue.

It looks like the lack of a .pom is the problem.

By default, Gradle 6 can't find dependencies unless they have metadata. This is a change from Gradle 5 behaviour. You can customise it by adding a metadataSources block to your repository declaration, like this:

repositories {
    maven {
        url = uri("https://repo.****.dev:443/artifactory/****-repo")
        metadataSources {
            mavenPom()
            artifact()
        }
    }
}

This means, "Look for the .pom first, but if there is no .pom, look for the .jar."

You might also want to add gradleMetadata() if the repo contains any.
