In the [gradle documentation](https://www.gradle.org/docs/current/userguide/writing_build_scripts.html#N10AF5) in the section about groovy basic, we have an example:

```
configurations.runtime.each { File f -> println f }

```

What the code was supposed to print? I write the simple build script containig this line:

```
apply plugin: 'java'

configurations.runtime.each { File f -> println f }

dependencies{
    project(':api') //This's just a project declared in the settings.gradle
}

```

and what the `gradle check` does is print nothing. What does it mean actually?
