How to add timestamp for artifacts in Jenkins - jenkins

Question

I have following Jenkisfile and I'm trying to upload the artifacts with a timestamp.
import groovy.transform.Field
#Field def timeStamp = Calendar.getInstance().getTime().format('YYYYMMdd-hhmmss',TimeZone.getTimeZone('CST'))
node {
stage('Creating some artifacts') {
sh 'touch hello.txt hi.txt'
}
stage('Uploading artifacts') {
def server = Artifactory.server ('art-1')
def uploadSpec = """{
"files": [
{
"pattern": "*.txt",
"target": "repo1/Dev/${env.BUILD_NUMBER}/*.txt.${timeStamp}"
}
]
}"""
def buildInfo1 = server.upload(uploadSpec)
server.publishBuildInfo(buildInfo1)
}
}
However, I'm getting the following error while trying this.

Are there any alternative/simple way to add timestamp in artifacts in Jenkins?
P.S.: I'm new to Jenkins groovy scripting and JFrog

Answer 1

The error message says that * is an invalid character for a file name so I don't think you can use it in the target field. However, the artifactory docs say you can do this instead (links for docs bellow):
def uploadSpec = """{
"files": [
{
"pattern": "(*).txt",
"target": "repo1/Dev/${env.BUILD_NUMBER}/{1}.txt.${timeStamp}"
}
]
In this code, {1} stands for "whatever got matched inside the first parenthesis in the pattern" (every open+close parenthesis in a regex defines a capture group).
Note: I don't use artifactory so I didn't test the above code, I am going off of the artifactory docs:
https://www.jfrog.com/confluence/display/RTF/Using+File+Specs
https://www.jfrog.com/confluence/display/RTF/Using+File+Specs#UsingFileSpecs-UsingPlaceholders
I'd also suggest you move the timestamp to the file name instead of the file extension, so that when you download the file, your computer knows which program to use to open it. So i'd change target to something like:
files shorted fist by name then by timestamp: repo1/Dev/${env.BUILD_NUMBER}/{1}-${timeStamp}.txt
files shorted fist by timestamp then by name:
repo1/Dev/${env.BUILD_NUMBER}/${timeStamp}-{1}.txt
