A file read permissions - Jenkins security

[Tal Yanai]

Hi,

I have 2 steps running one after the other.

The first step is a Linux shell execution, that simply produce an input file for the second step.  Something basic like echo "blabla" > /tmp/input.txt

The second step is a Java based plugin that is trying to read the input file, but failed complaining the file doesn't exist.   

For many years now, this was not a problem, but lately we have a customer that is facing such problem.

What can be set wrong in Jenkins that prevent from the second step to read the file?  (the file have read permissions on the disk, and is created by user root, not by the user who is logged into the Jenkins)

Thanks,

Tal.

The first build step is running on an agent, and you use Java APIs to try to access the file (which look on the master filesystem).

Thanks Daniel,

I suppose you mean for a “node”. I checked that. There’s only one Jenkins server and the file system is all within the same nfs so in any case there’s an access to any path.
