Running the command with environment variable set is also effective   Of course  you have to do it for each command you run  but you probably have a job script  so you probably only have one command per build   My job script is a python script that uses the environment to decide which python to use  so I still needed to put  usr local bin python2 7 in its path   PATH  usr local bin  lt my-command gt

This is how I solved this annoying issue   I changed the PATH variable as  sagar suggested in his 2nd option  but still I got different PATH value than I expected   Eventually I found out that it was the EnvInject plugin that replaced my PATH variable   So I could either uninstall EnvInject or just use it to inject the PATH variable   As many of our Jenkins jobs use that plugin  I didn t want to uninstall it     So I created a file  environment variables properties under my Jenkins home directory   This file contained the path environment value that I needed  PATH  PATH  usr local git bin    From the Jenkins web interface  Manage Jenkins - gt  Configure System  In that screen - I ticked the Prepare jobs environment option  and in the Properties File Path field I entered the path to my file   var lib jenkins environment variables properties   This way every Jenkins job we have receive whatever variables I put in this environment variables properties file

I found two plugins for that  One loads the values from a file and the other lets you configure the values in the job configuration screen   Envfile Plugin     This plugin enables you to set environment variables via a file  The file s format must be the standard Java property file format    EnvInject Plugin     This plugin makes it possible to add environment variables and execute a setup script in order to set up an environment for the Job

Michael   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

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

Here is what i did on ubuntu 18 04 LTS with Jenkins 2 176 2  I created  bash aliases file and added there path  proxy variables and so on   In beginning of  bashrc there was this defined     If not running interactively  don t do anything case  - in      i               return   esac   So it s checking that if we are start non-interactive shell then we don t do nothing here    bottom of the  bashrc there was include for  bash aliases    Alias definitions    You may want to put all your additions into a separate file like      bash aliases  instead of adding them here directly    See  usr share doc bash-doc examples in the bash-doc package   if   -f    bash aliases    then          bash aliases fi   so i moved  bash aliases loading first at  bashrc just above non-interactive check   This didn t work first but then i disconnected slave and re-connected it so it s loading variables again  You don t need to restart whole jenkins if you are modifying slave variables  just disconnect and re-connect

Solution that worked for me  source    bashrc  Explanation  I first verified Jenkins was running BASH  with echo  SHELL and echo  BASH  note I m explicitly putting    bin bash atop the textarea in Jenkins  I m not sure if that s a requirement to get BASH   sourceing  etc profile as others suggested was not working   Looking at  etc profile I found  if     PS1     then       and inspecting   PS1  found it null  I tried spoofing  PS1 to no avail like so  export PS1 1 bash -c  echo  PATH    however this did not produce the desired result  add the rest of the  PATH I expect to see   But if I tell bash to be interactive  export PS1 1 bash -ci  echo  PATH    the  PATH was altered as I expected   I was trying to figure out how to properly spoof an interactive shell to get  etc bash bashrc to load  however it turns out all I needed was down in    bashrc  so simply sourceing it solved the problem

Jenkins also supports the format PATH  lt name gt  to prepend to any variable  not only PATH   Global Environment variables or node Environment variables     This is also supported in the pipeline step withEnv   node     withEnv   PATH JAVA  path to java bin                      Just take note  it prepends to the variable  If it must be appended you need to do what the other answers show     See the pipeline steps document here      You may also use the syntax PATH WHATEVER  something to prepend  something to  PATH   Or the java docs on EnvVars here

I have Jenkins 1 639 installed on SLES 11 SP3 via zypper  the package manager   Installation configured jenkins as a service     service jenkins  Usage   etc init d jenkins  start stop status try-restart restart force-reload reload probe    Although  etc init d jenkins sources  etc sysconfig jenkins  any env variables set there are not inherited by the jenkins process because it is started in a separate login shell with a new environment like this   startproc -n 0 -s -e -l  var log jenkins rc -p  var run jenkins pid -t 1  bin su -l -s  bin bash -c   usr java default bin java -Djava awt headless true -DJENKINS HOME  var lib jenkins -jar  usr lib jenkins jenkins war --javaHome  usr java default --logfile  var log jenkins jenkins log --webroot  var cache jenkins war --httpPort 8080 --ajp13Port 8009 --debug 9 --handlerCountMax 100 --handlerCountMaxIdle 20  amp   jenkins   The way I managed to set env vars for the jenkins process is via  bashrc in its home directory -  var lib jenkins  I had to create  var lib jenkins  bashrc as it did not exist before

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

User · Answer

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
