Upload file in Jenkins input step to workspace
(1 answer)
Closed 3 years ago.
Upload (per progress bottom bar status) goes through in Jenkins. But don't see option to locate or fetch uploaded file from Jenkins.
Here is simple script with File parameters,
properties(
[
parameters(
[ file(name: "file1.zip", description: 'Choose path to upload file1.zip from local system.'),
file(name: "file2.zip", description: 'Choose path to upload file2.zip from local system.') ]
)
]
)
node {
stage("Fetch Uploaded File") {
sh '''
ls -l file1.zip file2.zip
ls -l ${WORKSPACE}/file1.zip ${WORKSPACE}/file2.zip
'''
}
}
Tried with def input file option per other post, but no luck of reaching uploaded file. Any inputs?
def inputFile = input message: 'Upload file', parameters: [file(name: 'data.ear')]
new hudson.FilePath(new File("$workspace/data.ear")).copyFrom(inputFile)
inputFile.delete()
With scripted full pipeline pasted above, getting below error..
[Pipeline] {
[Pipeline] stage
[Pipeline] { (Fetch Uploaded File)
[Pipeline] sh
[testSh] Running shell script
+ ls -l file1.zip file2.zip
ls: cannot access file1.zip: No such file or directory
ls: cannot access file2.zip: No such file or directory
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node

This is a known bug JENKINS-27413.
There is however a library with a workaround that can help you https://github.com/janvrany/jenkinsci-unstashParam-library. As described in the readme you can add this library to your Jenkins (Extending with Shared Libraries) and use it the following way:
library "jenkinsci-unstashParam-library"
node {
def file_in_workspace = unstashParam "file"
sh "cat ${file_in_workspace}"
}
