[news.eclipse.technology.equinox] Re: trying to build do p2 generation w

[Andrew Niefer <aniefer@xxxxxxxxxx>]

In Eclipse, only the Main class (from org.eclipse.equinox.launcher) is 
found from the normal java classpath.  Everything else is found through 
OSGi classloaders which don't use that classpath.

You can use a minimal set of bundles for your build, but it will need a 
config.ini to get everything started.  (Also more bundles than you 
listed below.)

The easiest way to get this is to use a product configuration file in 
eclipse.  Add org.eclipse.equinox.p2.metadata.generator (and perhaps 
exemplary.setup) then do "Add Required Plug-ins".
Export this product and you should end up with what you need to run the 
generator.  You can throw away the executable and eclipse.ini, but you 
need the configuration directory and all the plugins.  You can then 
start it like you have below, though only the equinox.launcher needs to 
be on the java classpath.
