Jenkins 在 PATH 中找不到二进制文件，并且似乎不是从 Linux 继承的

Question

I've tried everything for this an it's exhausted my knowledge. I'm trying to get Jenkins to use the Path from Linux and it's not working it seems.

Running Jenkins on RHEL Linux and Jenkins runs using the 'jenkins' user:

If I sudo su as the 'jenkins' user, I can see items like Blaze and Firefox on the Path:

(Both Jenkins and the server have been restarted multiple times since these have been on the path)

If I firefox -V while in a jenkins user bash, it works fine. In a Jenkins job that attempts to use the Firefox driver, it errors with the following:

Cannot find firefox binary in PATH. Make sure firefox is installed. OS appears to be: LINUX

In the System Info, it has PATH=/sbin:/usr/sbin:/bin:/usr/bin

Running as SYSTEM
[EnvInject] - Loading node environment variables.

The settings for the nodes are default, which I understand means it should inherit from linux

I also made a job that runs the following:

whoami
echo $PATH
firefox -V

This returns:

+ whoami
jenkins
+ echo /sbin:/usr/sbin:/bin:/usr/bin
/sbin:/usr/sbin:/bin:/usr/bin
+ firefox -V
/tmp/jenkins4835013049839580673.sh: line 4: firefox: command not found

No matter what I try, I can't seem to get Jenkins to use the 'correct' Path value. Is there something I'm missing, or is it as confusing as I am feeling?

Additional Stuff:

• Adding a symlink into /usr/bin also doesn't work for some reason.
• I can't add them as "Environment Variables" within the Jenkins config as it seems to break the pipeline jobs that don't need the additional binaries.

Can anyone help?

I had the same problem and could not execute my grails binary from jenkins, as it was added "programmatically" when i started my terminal, which did not apply to Jenkins. My solution was simply to symlink the grails binary to /usr/local/bin which was available in $PATH from Jenkins.

Symlink using: sudo ln -s /home/jenkins/.sdkman/candidates/grails/5.0.1/bin/grails /usr/local/bin
