We need to refresh our sandbox but have some not deployed components in it (because not fully tested yet).
So with force plugin for Eclipse I was able to fetch components from sandbox and now have many Apex code files and XML files with components metadata (see screenshots).
To test the restoring of components (before refresh) I deleted a custom flow in sandbox (not needed anymore) and tried to restore it from Eclipse. Related XML file is SF2BO_installation-2.flow, I tried to save it to server (sandbox) but that doesn't store it in sandbox, just gives error "Save error: Required field is missing: actionType".
Other option seems to deploy to sandbox, but that won't connect to our sandbox.
So my question is: how can I restore a component with force.com plugin (or VSCode or sfdx CLI)?
