Fetching uploaded files in Jenkins

Question

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
[Pipeline] End of Pipeline
ERROR: script returned exit code 2
Finished: FAILURE

Here is another failure attempt of trying it differently `node { stage("Upload File") { def inputFile = input message: 'Upload file', parameters: [file(name: 'data.zip')] new hudson.FilePath(new File("$WORKSPACE/data.zip")).copyFrom(inputFile) inputFile.delete() sh ''' ls -l data.zip ls -l ${WORKSPACE}/data.zip ''' } }` — vinWin, Dec 24 '19 at 12:13
And corresponding error being.. `[Pipeline] { [Pipeline] stage [Pipeline] { (Upload File) [Pipeline] input Input requested Approved by admin [Pipeline] } [Pipeline] // stage [Pipeline] } [Pipeline] // node [Pipeline] End of Pipeline org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: Scripts not permitted to use new java.io.File java.lang.String at org.jenkinsci.plugins.scriptsecurity.sandbox.whitelists.StaticWhitelist.rejectNew(StaticWhitelist.java:187) at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.SandboxInterceptor.onNewInstance` — vinWin, Dec 24 '19 at 12:14

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}"
}

Thanks for your response @Vitalii Vitrenko As it's binary, looked at slight variation as per here : https://stackoverflow.com/questions/57464227/upload-file-in-jenkins-input-step-to-workspace & is working now! – vinWin Dec 24 '19 at 14:59

Actually neither answer from https://stackoverflow.com/questions/57464227/upload-file-in-jenkins-input-step-to-workspace post is working not the solution which you pointed @Vitalii Vitrenko With other post it results in 'Can not open file '' as archive ' error and with solution which you pointed yields to following error : 'ERROR: unstashParam: No file parameter named 'file'' – vinWin Dec 24 '19 at 17:40
And to add, its binary file which I am looking to upload relatively huge, which is failing using either of approach – vinWin Dec 24 '19 at 17:47
