[dsdp-tm-dev] RE: RSE 2.0 API questions

["Oberhuber, Martin" <Martin.Oberhuber@xxxxxxxxxxxxx>]

Hello Anna,

it slightly depends on whether you need your code (plugin)
to be able and run unchanged (binary compatible) on any
future RSE versions or not.

If this is not so important for you, because you'd need
to change your plugin when RSE changes from 2.0 to 3.0
anyways, then I'd recommend just using the internal classes
and keeping the rest of your code unchanged.

If you need / want to be truly API compatible, see the 
EclipseCon Tutorial from last year for how to write code
that runs on the remote and parses output. You can either
install an IHostShellOutputListener, or run a 
SimpleCommandOperation.

get the slides and sample code from there

Cheers,
