[p2-dev] Re: [dash-dev] P2 ZIP Repos Cached

[Nick Boldt <nickboldt@xxxxxxxxx>]

Last I checked, p2 doesn't do jar:http: ... it only does these:

http://path/to/dir/
file:/path/to/dir
jar:file:/path/to.zip

So, to work around this, Athena will precache a repositoryURL pointing 
at http://path/to.zip in the downloadsDir and internally convert the URL 
to a local pointer (jar:file:) instead of an http one. First build it 
fetches it, subsequent builds it checks for the zip locally first and if 
the timestamps are the same, it won't refetch it.
