I recently installed the Jenkins JIRA Pipeline Steps 1.6.0 plugin.  I would like to use the plugin to download an attachment in a Jira task.

I am using the following in my jenkinsfile:

def attachment = jiraGetAttachmentInfo id: '3418787'
echo attachment.data.toString()
def attachment2 = jiraDownloadAttachment id: '3418787', file: 'DSWCPLAT-1537_ver1.zip', override: true
echo attachment2.data.toString()
def attachment3 = jiraDownloadAttachment id: '3454761', file: 'test.txt'
echo attachment3.data.toString()
sh 'ls -al'
sh 'ls -al /'

i am just not sure of the expectation here.  it looks like the call is working, as when i use an invalid id, it will throw a 401 exception and fail, but using the correct information for 2 different attachments, I get the following:

[Pipeline] jiraGetAttachmentInfo

Successful. Code: 200
[Pipeline] echo

Why am I not seeing this on my worker node?

Is there something that I need to do in addition to the jiraDownloadAttachment to write the file to the worker node?
