You do not currently have this command group installed. Using it
requires the installation of components: [beta]
Your current Cloud SDK version is: 322.0.0

Do you want to continue (Y/n)?
Possible solution
Add --quiet option to run emulator, so as to silently install beta component.

It seems the issue here is likely that the process is blocking on https://github.com/googleapis/java-datastore/blob/master/google-cloud-datastore/src/main/java/com/google/cloud/datastore/testing/LocalDatastoreHelper.java#L273
which never occurs as the components aren't present.
Perhaps this method https://github.com/googleapis/java-core/blob/375983090b3700b3fb6a1953626db7efca49cc51/google-cloud-core/src/main/java/com/google/cloud/testing/BaseEmulatorHelper.java#L94 needs a timeout?
