Here is the Groovy script I use, which gets the description from the log. You
can modify as required to use an environment variable (I think).
Matthew Webber
// This Groovy script must be run using a Jenkins "Execute system Groovy
script" build step
// A previous step must write a line in the log of the form defined in
"pattern" below
def currentBuild = Thread.currentThread().executable
def pattern = /^set-build-description: (.+)$/
// Parsing 20 most recent lines of the build log
log = currentBuild.getLog(20)
for (line in log) {
match = (line =~ pattern)
if (match) {
currentBuild.setDescription(match[0][1])
out.println "[set-build-description.groovy] Build description was set to:
" + match[0][1]
break
}
}
