----------------------------------------
Summary: Predefined parameters on a post-join build are evaluated
by a child job rather than parent
Key: JENKINS-12686
URL: https://issues.jenkins-ci.org/browse/JENKINS-12686
Project: Jenkins
Issue Type: Bug
Components: nodelabelparameter, parameterized-trigger
Reporter: Michael Conlon
Assignee: domi
I have a diamond build setup that runs across several machines. The first job
runs on the parent node, then kicks off jobs on multiple child nodes, as well
as on itself...then a join build is done on a grandchild node.
I have a list of predefined parameters, one of which recently failed on me
unexpectedly:
TIMESTAMP=${BUILD_ID}_${NODE_NAME}
I expect these predefined parameters to evaluate on the parent node, where they
are configured (this is how they are evaluated on the pass-off to its
children). However, I just witnessed a grandchild build evaluate these
environment variables during the join action, from a child node (The build_id
and node_names were changed). I'm guessing it was evaluated from the last
job/node to finish, but that wouldn't exactly explain all the other times this
has worked correctly.
