I’m thinking that this:
println “${TOOL_BRANCH}”
needs to be this:
println params[‘TOOL_BRANCH’]
what you cannot do is “Create” a new environment or parameter value inside your
build-flow and access that outside in a real post-build step.

Subject: Build Flow Plugin questions on how to access defined values
I am new to the build-flow-plugin and have been asked to add some steps to an
existing job. While I have a shell script that does this, it was requested
that I use the build-flow-plugin instead. I am familiar with Groovy as I use
it to access information within jenkins, but the DSL/Groovy build flow plugin
confuses me. Can someone explain to me how to grab a value from Jenkins, or a
value that is currently being used in existing build-flow, and then go and use
it in a later step after everything is completed to execute some action.
This is a reduced list of what is currently configured for the existing build
flow
bParent = build ("build_start",
TOOL_BRANCH : params['TOOL_BRANCH'],
TOOL_CHANGE_NUMBER : params['TOOL_CHANGE_NUMBER']
)
if (bParent.build.properties.environment['TOOL_CHANGE_MERGED'] == 'TRUE') {
return 0
}
parallel (
{build ("update_issue", EnvVarFile :
bParent.build.properties.environment['ENV_VAR_FILE']) },
{build ("verify_commit_message", EnvVarFile :
bParent.build.properties.environment['ENV_VAR_FILE']) }
)
My ultimate goal is to clean up after the steps listed above (rm -rf several
directories but keep certain directories). I have tried breaking this down to
just println a value from Jenkins, and everytime I do this, my script fails.
These are the actions I have taken and I included a brief comment about each
action.
println “${TOOL_BRANCH}” - my parameter from above
println “${BUILD_ID}” - Jenkins parameter
println “bParent.build.properties.environment['GIT_TREE']” - this is the
directory I want to clean up from the ENV_VAR_FILE, however I can use a
combination of other values, to obtain the same result
Whenever I try anything above or anything similar I get the following error.
What am I missing?
