If you have multiple nodes with a label of A, you will need to declare a
variable to hold the name of the specific node you ended up on in the first
"node" declaration, and then use that node in the third one:
def allocatedNode
node('A') { allocatedNode = $NODE_NAME } //NODE_NAME is an environment
variable provided by Jenkins
node('B') {}
node($NODE_NAME) {}
HOWEVER, be aware that this isn't always a safe thing to do, depending on
what your goal is. There is no guarantee that the workspace that was used
in the first node block will still be there when the third block gets
there. Even if it is, there is no guarantee that the third block will use
the original workspace. It probably will most of the time, but not
guaranteed. Depending on what you are doing, you may need to allocate a
custom workspace (still not a guaranteed solution), move to a separate
directory, stash/unstash the things you need between nodes, or some other
solution.
