Is it even possible to "install its parent feature again" without uninstalling 
the feature first?
This results in a no-op


Unless the plug-in in question was installed manually, uninstalling the parent 
feature should uninstall the plug-in too. Installing the parent feature again 
will install the plug-in again too. Right?
Right. Note though that if the artifact (e.g. the plugin) has not been garbage 
collected (p2 has a GC that eventually deletes artifacts, this is necessary 
because some files can’t be deleted immediately because they are in use) , then 
an uninstall followed by an install may not cause a new file to be downloaded.

If a plugin is deleted from disk, p2 will not download it again, nor will it 
check for its presence or validity.
As you guessed this is because the setup of p2 in Eclipse is taking a 
metadata-first approach to provisioning. What I mean here is that p2 knows from 
the content of the profile that the IU for the plugin is installed and it won’t 
question this.
There is no tool available to check the validity of an install, but it could be 
written as a side application.

Subject: [p2-dev] Question about deleting a downloaded p2 plugin

If I delete a plugin from my plugins folder, and then go to install its parent 
feature again, will p2 download the plugin again?  Does it check to make sure a 
plugin actually exists or does it just rely on its metadata?  If it’s the 
latter is there any way to force it to check?

Thanks,

-Josh
