detektGenerateConfig ignores detekt.config paramenter

[BraisGabin]

Expected Behavior

./gradlew detektGenerateConfig creates the config file in the defined config path defined in the configuration

detekt {
    config = files("$rootProjectDir/detekt-config.yml")
}

Observed Behavior

The config is ignored and the task creates it in the default path: config/detekt/detekt.yml

Steps to Reproduce

Configure the plugin like this:

detekt {
    config = files("$rootProjectDir/detekt-config.yml")
}

and then run: ./gradlew detektGenerateConfig

Your Environment

• Version of detekt used: 1.7.2 (reproducible in 1.6.0 too)
• Version of Gradle used (if applicable): 5.6.1
• Operating System and version: macOS

I had some problems with config as well. But this code fixed the issue for me:
config.from(files("${project.rootDir}/config/quality/detekt/default-config.yml"))

Right, the cli respects the config parameter but the gradle plugin not.
So the fix is quite easy in the gradle plugin.
Not sure if this is a bug or feature. I would consider this for a 1.X.0 release as this will need a migration entry.

Ok, I was trying to fix this but it's not that easy. We allow to add multiple paths in config. So, which one should be used?

[arturbosch]

Let's go with the last one as it overwrites the properties of the preceding. E.g.: config1,config2 we would use config2
