I am running Jenkins from user jenkins thats has $PATH set to something and when I go into Jenkins web interface, in the System Properties window (http://$host/systemInfo) I see a different $PATH.

I have installed Jenkins on Centos with the native rpm from Jenkins website. I am using the startup script provided with the installation using sudo /etc/init.d/jenkins start

Can anyone please explain to me why that happens?


Two things:

When Jenkins connects to a computer, it goes to the sh shell, and not the bash shell (at least this is what I have noticed - I may be wrong). So any changes you make to $PATH in your bashrc file are not considered.

Also, any changes you make to $PATH in your local shell (one that you personally ssh into) will not show up in Jenkins.

To change the path that Jenkins uses, you have two options (AFAIK):

1) Edit your /etc/profile file and add the paths that you want there

2) Go to the configuration page of your slave, and add environment variable PATH, with value: $PATH:/followed-by/paths/you/want/to/add

If you use the second option, your System Information will still not show it, but your builds will see the added paths.

Confluence Mobile, hudson.model.Environment public abstract class Environment extends Object. Represents Adds environmental variables for the builds to the given map. Couldn't you just add it as an environment variable in Jenkins settings: Manage Jenkins -> Global properties > Environment variables: And then click "Add" to add a property PATH and its value to what you need.

I kept running into this problem, but now I just add:

source /etc/profile

As the first step in my build process. Now all my subsequent rules are loaded for Jenkins to operate smoothly.

Environment (Jenkins core 2.241 API), Gets the platform for which these env vars targeted. static EnvVars · getRemote(​hudson.remoting.VirtualChannel channel). Obtains the environment variables of a  Creates environment variable override for launching child processes in this node. Whereas NodeProperty.setUp(AbstractBuild, Launcher, BuildListener) is used specifically for executing builds, this method is used for other process launch activities that happens outside the context of a build, such as polling, one time action (tagging, deployment, etc.)

You can also edit the /etc/sysconfig/jenkins file to make any changes to the environment variables, etc. I simply added source /etc/profile to the end of the file. /etc/profile has all all of the proper PATH variables setup. When you do this, make sure you restart Jenkins

/etc/init.d/jenkins restart

We are running ZendServer CE which installs pear, phing, etc in a different path so this was helpful. Also, we don't get the LD_LIBRARY_PATH errors we used to get with Oracle client and Jenkins.

EnvVars (Jenkins core 2.241 API), Builds up the environment variable map that's sufficient to identify a process as ours. EnvVars, Computer. getEnvironment(). Returns cached environment variables  In Jenkins, often we need to build up "environment variable overrides" on master, then to execute the process on agents. This causes a problem when working with variables like PATH.

I tried /etc/profile, ~/.profile and ~/.bash_profile and none of those worked. I found that editing ~/.bashrc for the jenkins slave account did.

Uses of Class hudson.EnvVars (Jenkins core 2.238 API), 1.2 Using Groovy/Java. To create global environment variable, we need to use below code. import hudson.EnvVars; import hudson.slaves. We use the getEnvironmentmethod that returns a hudson.EnvVarsobject. This is a Groovy map so we can already use the eachmethod to go over the keys and values. This however only seem to list the internal variables of Jenkins and for example PATHwas not in the list even though we can access it as env.PATH.

The information on this answer is out of date. You need to go to Configure Jenkins > And you can then click to add an Environment Variable key-value pair from there.

eg: export MYVAR=test would be MYVAR is the key, and test is the value.
