Hi!

I'm using a "small" Groovy-script (with scriptler plugin) to copy files from or to the workspace of different builds, which maybe located on (different) agents.
My first approach was to use (at least) the method FilePath.copyRecursiveTo(include_pattern, exclude_pattern, Destination), which is suitable if the destination-channel is equal to source-channel (same node or within master) or one of these channels is null (I.e, on master).

But, if files should be copied between different agents, all files are copied to the master (at the given 'raw' path). Okay, I've found a solution for my script by using an temporary TGZ-File on the master as intermediate storage.
Looking into the source-code of FilePath.copyRecursiveTo seems to ignore this 'illegal' combination and assumes, that the target is located on the master.

Maybe the Core-implementation should detect this 4rd combination (dest-channel != src-channel and booth are not null) as unexpected and throws an exception (like 'unsuitable communication-partners').

Best regards from Salzburg,
