                            NOTE: Users occasionally misuse the id "local" for remote repos which screws up the metadata
                            of the local repository. This is especially troublesome during snapshot resolution so we try

and set `networkPolicy.enabled` to `true`.

For Kubernetes v1.5 & v1.6, you must also turn on NetworkPolicy by setting
the DefaultDeny namespace annotation. Note: this will enforce policy for *all* pods in the namespace:

```
kubectl annotate namespace default "net.beta.kubernetes.io/network-policy={\"ingress\":{\"isolation\":\"DefaultDeny\"}}"
```

 * Note that the aggregator project is required to have a {@code pom} packaging.</p>
