Execution context from within an jenkins build

[Schalk Neethling]

Hey all,

Quick question regarding ant and Jenkins. So, I am getting the following error : "Execute failed: java.io.IOException: Cannot run program" at the first step in my Ant build step. When I run the same Ant target via the terminal as the jenkins user it executes without a problem. This leads me to believe that there is a difference between running Ant directly via the terminal and running Ant from within a Jenkins build.

What is different between executing from the terminal directly and having the Ant target executed from a jenkins build? Is there some config I might be missing?

Thanks,
Schalk

Did you configure ant location in the Manage Jenkins / Configure System / Tool locations?

Hey Sami,

So here is my system config

Home Directory :: /Users/Shared/Jenkins/Home

Under Global Properties

Tool locations for Ant as follows:

/usr/local/apache-ant-1.8.2

JDK installations :: /Library/Java/Home

Git installations :: git

Ant installations :: /usr/local/apache-ant-1.8.2

SSH Server set to random

No password SSH private key and I have a Github web hook set up that verifies perfectly.

With all of the above I am still getting the following:

The error "Cannot run program "csslint": error=2, No such file or
directory" tells me either you do not have the program csslint in your
system or it is installed somewhere where ant isn't looking for it.

You can check the value of PATH environment variable by e.g. going to
$JENKINS_URL/systemInfo

If the value of PATH isn't what you want it to be, you can change it
at $JENKINS_URL/configure under the heading "Environment variables"

Hey Sami,

I updated the PATH by going to $JENKINS_URL/configure under the heading "Environment variables" and adding a new env entry as follows:

Name: PATH
Value: /opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/git/bin

The value above is the same $PATH info I get when echoing from the terminal as the jenkins user. When heading back to $JENKINS_URL/systemInfo however, the value for PATH in the Environment variables table has not changed.

Thanks for the all the assistance so far,

Hey Sami,

Even though it does not change on the sys info screen as stated, it does clearly take effect and my build no completed successfully.

Thanks a million,

[Sami Tikka]

The sys info page shows the value of PATH in the environment of
Jenkins itself. The environment variable setting you added is the
value of PATH which Jenkins sets into the environment of processes it
starts.
