Gradle - Could not get unknown property 'scm&#

问题:

Execution failed for task ':app:iterateDeclaredDependencies'.
> Could not get unknown property 'scm' for configuration container of type org.gradle.api.internal.artifacts.configurations.DefaultConfigurationContainer.

I'm using the exact code snippet from Working with Dependencies

I don't know what scm is here but autocompletion seems to suggests that all is good, no?

Versions I'm using:

------------------------------------------------------------
Gradle 5.4.1

To query specific dependency sets, they must be declared first. scm doesn't exist, thus Gradle fails with an error message. Additional dependency sets can be added like this:

configurations {
    scm
}

(Defining custom configurations)

Try with one of the defaults instead, for example implementation.

I'm not an IntelliJ IDEA user, so cannot tell exactly why autocompletion works in this case.
