If a dependency resolution trigger another dependency resolution, the org.gradle.initialization.DependencyResolutionLogger class throw an IllegalStateException.

This happen for instance with the following script

repositories {
	flatDir {
		dirs "."
	}
}

configurations {
	fragments
}

repositories {
	flatDir {
		dirs configurations.fragments
	}
}

configurations {
	compile
}

dependencies {
	compile name:'foo'
}

task foo << {
	println configurations.compile.files
}

Mainly the directories of a flatDir repository are resolved as dependencies.

Running gradle foo throws an IllegalStateException

If the fragments configuration is resolved "a-priori", it works correctly. For instance by adding to the script:

afterEvaluate {
	configurations.fragments.files
}
