The name of plugin [Stashed File Parameter][1] is uploadfile [File Parameter | Jenkins plugin] https://plugins.jenkins.io/file-parameters/
I use this plugin to upload files using Jenkins pipeline.
The pipeline works fine / successfully when I upload any file; but fails with error when no files are uploaded.
My Jenkins declarative pipeline is as below.
pipeline {
agent {
node {
label 'Ansible_host'
}
}
stages {
stage('Precheck') {
steps {
unstash 'uploadfile'
script{
if ( uploadfile_FILENAME != "" )
{
sh "mv uploadfile '$uploadfile_FILENAME'"
}
if ( uploadfile_FILENAME != "" )
{
echo "File is uploaded from localhost"
}
else
{
echo "File is uploaded from $source_host"
}
}
sh "echo Im from Jenkins>/tmp/jenkinsmoht.txt"
}
}
}
}
Error when no files are uploaded:
[Pipeline] End of Pipeline

Finished: FAILURE
In the earlier versions of Jenkins, this error was not seen.
Can you please suggest how can I avoid this error when no files are uploaded using the plugin?
After reading the plugin documentation, I understand that uploadfile is a build parameter of type stashedFile defined in the job configuration page and it returns the original filename as the environment variable uploadfile_FILENAME.
Since your script already works when there is a file to upload, you can rewrite the if conditions as:
if (env.uploadfile_FILENAME) {
sh "mv uploadfile '$uploadfile_FILENAME'"
echo "File is uploaded from localhost"
} else {
echo "File is uploaded from $source_host"
}
In this case, when there is no file to upload, the value of env.uploadfile_FILENAME will be null or an empty string and the if condition will return false without throwing the No such property error.
