= Support for p2.mirrorsURL =
According to http://wiki.eclipse.org/Equinox/p2/p2.mirrorsURL just add:
<property name="p2.mirrorsURL" value="http://www.eclipse.org/downloads/download.php?file={repository_path}&format=xml"/>
Since webmaster thinks that we have been hit by this issue recently (https://bugs.eclipse.org/bugs/show_bug.cgi?id=373352) this makes me think even more about how to integrate this into our builds. As last means of resort I'll write a bash script that unzips artifacs.jar, adds the property to the artifacts.xml, and zips the file again.
But I wonder how much effort it takes to add this in Tycho's eclipse-repository packaging since tycho generates these files?
It wouldn't be specify to Eclipse; just a generic support for properties - I think.
= Adding support for p2.index =
The file looks like this:
version = 1
metadata.repository.factory.order = compositeContent.xml,\!
artifact.repository.factory.order = compositeArtifacts.xml,\!
Whether it's "xml" or "jar" should depend on the "compress" property we already specify in the eclipse-repository.
= Enabling download stat in your repository =
And if we are already on defining properties: to enable download stats it's...
...for artifacts.xml/repository:
<property name='p2.statsURI' value='http://your.stats.server/stats'/>
...for bundles:
<property name='download.stats' value='test.plugin1.bundle'/>
http://wiki.eclipse.org/Equinox_p2_download_stats
So, in theory it's just adding properties and looks from outside like a simple thing to do. But how long it takes to implement it - at least the p2.mirrorsURL feature - I've no idea. But maybe a tycho committer knows better?
