Hi all,

I was wondering if there is any API to read from a given plugin.xml and
get information on the extended extension points. I cannot use the
extension registry for this since the plugin.xml I am trying to retrieve
information from is in one of the workspace's plugins, not an installed one.

I did find PluginModel, IPluginModelBase, IPluginModel ... but all these
are either deprecated or internal. Is there no public API for such
needs? Re-writing a parser for this seems overkill to me.

How about using the PluginRegistry API from PDE:

org.eclipse.pde.core.plugin.PluginRegistry

You should eventually be able to get an IExtensions or IExtension for
your model.

Let me know if you need more help.

Cheers,

Thanks Chris, this seems to be exactly what I was searching for. I
didn't find the actual entry point to all of this API :).

A little off subject but since I see this I might also get the info :
does this provide a way to get a default class loader for the plugins of
the workspace without launching a second runtime? Could be awesome to
test classes currently in development (might prove a little error-prone
but ... :)).

So, as of Eclipse 3.5M4, we support exporting plug-ins from the
workspace in the current host:

http://download.eclipse.org/eclipse/downloads/drops/S-3.5M4- 200812111908/eclipse-news-M4.html#PDE

See, "Single-click export and install into running platform"

Cheers,

Err, that would be Eclipse 3.5M3

Thanks Chris, I'll definitely have a look into this, seems like a great
feature :). A shame it only appeared in 3.5 though :(
