But it is an invalid configure closure for a Configuration.
This example creates the `conf` Configuration immediately.
During `resolve` task execution, the `distributions` block executed as if it were declared at the script-level:

```groovy
configurations {
    conf.incoming.afterResolve {
        distributions {
            myDist {
                contents {}
            }
        }
    }
}

        setCanBeDeclaredInternal(allowed);
    }
