I am trying to override TMPDIR for builds kicked off on one of my nodes.
I've added a new value in the node properties environment variables:
But when I run my job, TMPDIR is still set to the system value. ZIG does get set, however:
# Output from job running `env`
TMPDIR=/var/folders/nf/p0pz9cv93wz8m314wyk3yp_h0000gn/T/
ZIG=Zag
The same thing happens if I add the environment settings to the Jenkins master config. I can successfully use the EnvInject Plugin to change it on each job, but we have a number of jobs and I would really prefer that it be a node configuration (the node has a dedicated build drive).
How can I override TMPDIR for all builds launched on this node?
I am using Jenkins 1.624 on OS X Yosemite 10.10.5.
I had the EnvInject plugin installed, which was preventing the environment variables from being overridden (even though I wasn't using it, and it didn't work when I turned it on anyway).
I uninstalled that plugin and now my problem is gone.

I have setup Jenkins with a master node running Ubuntu and a slave node. Currently Jenkins use to build Android app (master and slave have different ANDROID_SDK_ROOT environment variables).
For slave I have configured environment variables as below:
The free style project run OK and the slave able to pickup the environment variable. A problem happens when I run multibranch pipeline job. It seems the job cannot pickup the environment variable always show error:
SDK location not found. Define location with an ANDROID_SDK_ROOT environment variable or by setting the sdk.dir path in your project's local properties file at
What is the root cause and how to make multibranch pipeline able to pick up correct environment variable?
Updated: I detect the problem because slave cannot override environment variable value set by master. But I don't know how to make slave able to override environment variable set by master.
I'm using a remote agent/slave to build my project in Jenkins via SSH.
Although the correct PATH environment variable is available when SSH'ing to it with the same user, it's not available when Jenkins tries to use the agent for building.
With the pipelines DSL, I was able to add it to my environment at runtime.
environment {
PATH = "/usr/local/bin:$PATH"
}
But I want this location in the PATH variable at all time, without this configuration. Any pointers on how to configure this for my agent/slave; whether it is in the jenkins node configuration or on the machine itself?
Just for anybody who is having the same issue.
When adding a new node in Jenkins, the master caches the environment variables of this node, but doesn't update it afterwards, to avoid breaking the configuration.
If you update the environment variables on the node itself, this changes won't be available for builds from the Jenkins master. You have to re-add the node or add environment variables in the configuration of the node.
i have a little problem.
Our setup consists of 1 Master Jenkins and 2 Slaves, both Slaves use a different SVN Location String, which we saved in an Environment Variable... but both of them start the same .dll for a Test - Now my problem is that when i use %SVN_Location% that it takes the Environment Variables from the computer i run the build (the master).
So my question is there a way to tell him somehow to execute the %SVN_Location% not on the computer where the build starts, but on the computer where the slave runs
Use EnvInject to record the value you want to file
Use Copy To Slave to move the file to slave
User EnvInject on slave to load value to environment variables, before the SCM step
I managed it myself after some more Research to actually get the Environment Variable directly from the Slave and use it as a Parameter for the Master Node.
With the Plugin Dynamic Parameter by using a Dynamic Parameter and the Default Value Script: System.getenv("SVN_Location_TP1") and the checkbox Remote Script checked.
When starting the build with parameters now, it automatically loads via remote script the Environment Variable from the slave and uses it as a parameter for the jenkins execution, which can be used with %SVN_Location_TP1% (in my example)
I am making use of a batch script that is supposed to run on a slave node, which makes use of Sahi. The environment variable for Sahi is set as 'SAHI_HOME' on the node.
When I run the batch I figure out, it is not able to locate Sahi classes.
How do I enforce Jenkins to make use of environment variables set on the slave? I mean is there any way to fetch environment variables set on a slave node?
We got around this issue by installing and updating Sahi automatically. There is a nice Jenkins Plugin: https://wiki.jenkins-ci.org/display/JENKINS/Custom+Tools+Plugin
You just need to place a Sahi Zip somewhere for Jenkis to access. The custom tool plugin automatically unpacks archives and creates a toolname_HOME environment variable.
Just name your tool SAHI and you have Sahi and $SAHI_HOME on every job and node you need.

I ran into a similar issue with my AIX slaves. The issue is that the .profile file is not executed when a non-interactive shell is started. Therefore, you have several options.
Make sure that the environment variable is set in the environment file (in AIX, I can set the ENV variable to a filename that will be executed for both interactive and non-interactive shells.) I think the .kshrc file might qualify too.
Set the environment variable in the node configuration
set the environment variable in the master configuration
set the environment variable in the job (needs env inject plugin)
set the environment variable explicitly in the bash script
I have a Jenkins Slave (A Windows PC) which has the JAVA_HOME environment variable. I updated the Java version on the Slave so I also updated the Environment Variable.
When I look at the system properties of this Slave via Jenkins web interface the JAVA_HOME property is reported as the old one.
Running echo %PATH% on the Windows PC shows the correct values.
Running println System.getenv("PATH") on the Jenkins Node script console for the Slave shows the old JAVA_HOME value.
I have tried to delete and add the Slave again and restarted Jenkins server. Still the old value is not updated.
Any thoughts?
This is a bug in Jenkins: https://issues.jenkins-ci.org/browse/JENKINS-27739
3 ways to solve (I have personally confirmed each):
Update Jenkins to >=1.617 (Recommended)
Restart Jenkins master
Delete Jenkins slave, then re-add it
Hudson/Jenkins does not use the slave environment variables as it supports multiple java versions so you configure the java home environment variables in the GUI.
What you need to do is go to Manage Hudson/Jenkins then choose Manage Nodes. Choose the Node you want to configure from the list and then choose Configure. Down the bottom there's a Node Properties section. Check the Tool Locations checkbox. Click on Add then Select your JDK in the dropdown list and add the new path to it.
Restart the slave, this fixed the issue on my configuration.
You can update your Jenkins version, it will solve it. Otherwise this worked for me (Jenkins 1.6, build/test node: MacOSX Mojave):
First install java 8 in your build/test node using the commands:
brew update
brew cask install caskroom/versions/java8
Then in Jenkins web panel click on your build/test node, then click on Configure and then click in the Advanced... button, this will show you multiple text fields. Then in the JavaPath field add the path to your java 8.
For me this path is like:
/Library/Java/JavaVirtualMachines/jdk1.8.X_XXX.jdk/Contents/Home/bin/java
Note: remember replace X_XXX with your java 8 version before.
Then Save.
After that disconnect the build/test node and connect it again. This should solve the problem.

No restart required.
Manage Jenkins -> Manage Nodes and Clouds
Click on the desired slave. Then choose "Disconnect" from the panel.
Slave will auto re-connect. If it doesn't, click on "Launch".
This will refresh environment variables including "PATH".
