Passing build parameters downstream using groovy. Jenkins build pipeline

Question

I've seen a number of examples that execute a pre build system groovy script to the effect of

import hudson.model.*
def thr = Thread.currentThread()
def build = thr?.executable
printf "Setting SVN_UPSTREAM as "+ build.getEnvVars()['SVN_REVISION']  +"\n" ; 
build.addAction(new ParametersAction(new StringParameterValue('SVN_UPSTREAM', build.getEnvVars()['SVN_REVISION'])))

Which is intended to make SVN_UPSTREAM available to all downstream jobs.

With this in mind I attempt to use $SVN_UPSTREAM in a manually executed downstream job like

https://code.mikeyp.com/svn/mikeyp/client/trunk@$SVN_UPSTREAM

Which is not resolved causing an error.

Can anyone spot the problem here?

Answer 1

The bleeding edge jenkins build pipeline plugin now supports parameter passing. Eliminated the need for the groovy workaround for me.
