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?
