Yeah we can fix that part, and then the build command
would execute. Other things like error parsing or managed build rely on
the URI though, so on the whole there could be problems, depending.

Dave/Greg, can you please file a defect on the execution issue?

Chris,

If the location of the project remains the same, but only the host that
the build provider is pointing to is changed, shouldn't this work (assuming
a shared filesystem)? It looks like the remote connection is cached in
RemoteBuildServiceProvider, so although changing the connection in ServiceProviderConfigurationWidget
changes the name in the provider properties (RemoteServicesServiceProviderContributor#updateProvider),
it doesn't change the actual connection. Perhaps if the RemoteBuildServiceProvider
checked the connection name property against the current connection name,
it could flush the cache and open a new connection if they were different?

Right now that scenario is not supported. Part of the
problem is many parts of CDT and RDT get information about the project's
location from its URI location. In your scenario, the URI location hasn't
changed, just the service model.

Also, for this to be able to work at all, you'd need to have a shared filesystem
such that the project files were visible to both machines, or a copy of
them. There's nothing in RDT currently that will transfer the files to
another machine.

We do want to support this in the future, as this is an important and common
use case. We just have not had the resources to get there yet.

I have a case where a remote project was created with the remote host specified
as z25c2s2. z25c2 has a filesystem which is shared with a number of other
systems, including z25c2s1. The remote project was created in that directory.

I am able to build the project on z25c2s2 without problems. However, I
also want to build this project on z25c2s1 (z25c2s1 is AIX, z25c2s2 is
Linux, although both could be Linux or both AIX) 

I have remote tools connections defined to both z25c2s1 and z25c2s2. If
I edit the service configuration for the remote project and cange the target
connection for the build service, the build still runs on the node te project
was defined for, as verified by putting a 'hostname' command in the makefile.
Closing and re-opening the project results in the build still running on
the original node. If I restart Eclipse, ten the build runs on the second
(z25c2s1) node. 

This is with the PTP 4.0.7 build. 

Should I be able to use remote build in this manner were I can switch build
target machines?
