Bash Script Fails During Jenkins Build But Does Not Fail Locally

Question

I've been trying to debug this issue all day with no success.

Issue: Bash script executes successfully on a Linux CentOS7 VM (jenkins build agent) but fails during Jenkins build.

Here's the simple script.

#! /bin/bash
echo "before beyond compare command"
bcompare @"bc_report.ps1" "./Output_Base/<Folder_Name>" "./Output_Compare/<Folder Name>" "Report.html"
echo "after beyond compare command"

The output in the Jenkins build log is just:

before beyond compare command
after beyond compare command

When viewing the VM during the Jenkins build, I'm not seeing an artifact being produced. The user during the Jenkins build is Root, when executing the script locally, I'm also doing so as Root with success.

I'm pretty sure this is a Jenkins issue, just can't seem to figure it out. Anyone seen something similar?

Beyond Compare 4 for Linux requires an X-Window/GUI session to run, even for scripts. As a cron job or in an SSH terminal without an X-Window client, Beyond Compare for Linux scripts will fail to run. This might be what is causing your Jenkins job to fail.

Beyond Compare 4 for Windows doesn't have the GUI session requirement for scripts. Beyond Compare 4 for Linux and macOS both require a GUI session for scripts. Removing the GUI session requirement for scripting on Linux and macOS is on the feature request list for a future version.
