Ansible Conditionally Synchronize if Directory Exists

I would like to use Ansible's synchronize module to transfer files to a remote server based on a condition. The condition, is that the directory and its contents exist on the source server.

For example:

First play, check if the directory exists on the localhost:

hosts: localhost
stat:
  path: some/path/to/dir/
register: st

Then, on the second play, use that variable in a when statement to conditionally use the synchronize module:

hosts: remote_hosts
synchronize:
  src: some/path/to/dir/
  dest: some/dest/path
when: st.stat.isdir is defined

My problem is that the st variable can't be used between plays, so how can I only run the synchronize task if the directory exists.

I would put them in the same play, but they're using different hosts as you can see.

My Ansible version is 2.3.1.0

You have a couple options. You can put the localhost task in your play with remote_users and use delegate_to: localhost.

stat:
  path: some/path/to/dir/
register: st
delegate_to: localhost

Or you can keep the localhost play as is and reference localhost's variables using hostvars in the remote_hosts play.

hosts: remote_hosts
synchronize:
  src: some/path/to/dir/
  dest: some/dest/path
when: hostvars['localhost']['st'].stat.isdir is defined
