[BUG] Error during gradle build: Cannot choose between the following variants of org.openapitools:openapi-generator-gradle-plugin:7.3.0

Description

I have a gradle project that uses the following dependendy in its buildscript:

buildscript {
	repositories {
		[...]
	}
	
	dependencies {
		classpath 'org.openapitools:openapi-generator-gradle-plugin:7.3.0'
	}
}

apply plugin: 'org.openapi.generator'

openApiGenerate {
    generatorName.set("html2")
    inputSpec.set("$rootDir/src/Resources/Documentation/My.yaml")
    outputDir.set("$rootDir/bin/apiGenerator")
}

When I run the build, I get the following error: during the dependency resolution step:

   > Could not resolve org.openapitools:openapi-generator-gradle-plugin:7.3.0.

         project :

          - sourcesElements
        All of them match the consumer attributes:
          - Variant 'javadocElements' capability org.openapitools:openapi-generator-gradle-plugin:7.3.0:

I have tried several things in order to choose a variant, but nothing I tried helped, and I was unable to find an explanation of how to solve this problem anywhere.

However, if I use version 6.6.0 instead, it works just find.

Either make it so that one of those two variants is automatically chosen as a default value, or provide guidance in the documentation about how the build.gradle should be adjusted it this happens.

Start with the build.gradle dependency example and compare resolution of org.openapitools:openapi-generator-gradle-plugin:7.3.0 with 6.6.0. Investigate how the Gradle plugin artifact publishes and selects variants, then verify the result with the reported build configuration. Done means the 7.3.0 dependency resolves correctly or the required build.gradle adjustment is documented.
