Re: [equinox-dev] IWeavingServiceFactory.createWeavingService takes a Bu

[Thomas Watson <tjwatson@xxxxxxxxxx>]

It is a bit more involved to deploy this into your Kepler instance.  You have to be running a Kepler instance with a workspace that has loaded both the org.eclipse.osgi and org.eclipse.osgi.compatibility.state projects.  Then you have to export the projects using "Export->Plug-in Development->Deployable plug-ins and fragments" and for the destination you have to select "Install into host. Repository:".  This will deploy the new framework to your running installation and you must then restart Eclipse.  If all goes well Eclipse will restart successfully on the new framework.

Note that this is not ready for prime-time, so I suggest you do this on a Kepler installation that you don't mind blowing up.  I find it easier to just run Eclipse on the new framework by launching a self-hosted Eclipse instance from your Eclipse workspace while you have the org.eclipse.osgi and org.eclipse.osgi.compatibility.state projects loaded.

Hi Tom,

Thanks for taking a look at this.  AJDT is one of the main consumers
of org.eclipse.equinox.weaving.hook through the
org.eclipse.equinox.weaving.aspectj bundle.  It looks like you have
also updated the org.eclipse.equinox.weaving.aspectj bundle.  I will
get a chance to try this out next week.  Just to be sure, if I check
out this branch of equinox and drop the osgi bundle into Kepler, will
things hang together?

regards,
Andrew
