wfollonier FYI

kansasmann Thank you for the report.

I will not have the time to investigate this case further this week.

Could you try using the WAR provided in JENKINS-56114 ? As they were also using Windows Server, that could the same root cause.

In addition, did you try with the escape hatch: java.exe -Dhudson.model.DirectoryBrowserSupport.allowSymlinkEscape=true -jar jenkins.war ? (in both your current version and in the WAR provided in the other ticket)

Then could you give me more information about your configuration, like are you using Docker inside your Windows Server, or just running java -jar ..., or using the service?

If you can provide also additional information from the log of the build, that could be useful. Also, what is the content of the userContent in your instance (in terms of type, not the real files, but to know if there are symlinks, what are their targets, or just image files?)

Thank you in advance for your next answer that will help me helping you

Wadeck Follonier: I cannot try using the WAR from JENKINS-56114  as this is a production system.  I will try to bring up a new jenkins and try it.
To answer your other questions:

• we are using the escape hatch -Dhudson.model.DirectoryBrowserSupport.allowSymlinkEscape=true
• we are NOT using docker, just running the jenkins windows service
• userContent has a mix of files, folders, and directory junctions (symlinks)

The build logs have no real information in them as it was a silent failure, because the zip was empty.  The gradle code used was

def f = new File("$buildOutput/staging.zip")
if (!f.exists()) {
     new URL('http://myJenkins:8080/userContent/archive/components/Staging/*zip*/staging.zip').withInputStream{ i -> f.withOutputStream{ it << i }}
}
copy
Unknown macro: {     from zipTree(f.getAbsolutePath())      into("$buildOutput/config/") }
f.delete()

From the UI, this is the Staging folder (this is not the actual folder used but shows the problem):

If i then click on the (all files in zip), the Staging.zip file gets generated but its only 1KB

And if its opened with 7zip the file is empty

If I dump the file using od -c i see no content

Hope this additional information helps!

Is this obsolete after recent changes in weekly releases?
