I have the following setup:
Jenkins -> Ant script -> Python script -> Interact with Selenium
I run Jenkins on a windows box. My Jenkins calls an Ant script which calls a python script which interacts with Selenium. The problem I have is that the http_proxy environment variable is defined and points to a proxy, that is intented to access the internet and not my system under test. When I run my Jenkins job I get a error message from the proxy along the lines that he could not access my system under test.
How can I disable the http_proxy in Jenkins so that it won't pass them to Ant -> Python -> Selenium?
Use EnvInject plugin to reset the variable in a build step before you run ANT.
Maybe try setting the variable in the jenkins settings page (override the default), or in the job (as a parameter). Both options will override any existing value on the system. Is this what you need?

If there is a Jenkins shell script build step, environment variables are set so that, for example, if you echo $WORKSPACE you see the current working directory. I am writing a custom plugin which also can execute shell commands but WORKSPACE is not set when this plugin executes.
I could see that Jenkins sets all those env variables prior to executing the shell commands the Jenkins project specifies so that they would not be already set for a custom plugin. If that is the case, it would seem like there is no way to access those env variables.
But if there is a way to obtain the values of the env variables that would be useful.
I am getting errors from the durable task plugin when I run my pipeline dsl jenkins job.
The error message suggests that I should use:
-Dorg.jenkinsci.plugins.durabletask.BourneShellScript.HEARTBEAT_CHECK_INTERVAL=300
This is the error I get:
\workspace\ne-sw-manifest_master-5ZF5EWBP7EVBXEBF6AS3C6UQLIXLCS3HRKYND6TPQAPIKZPFBDLQ#tmp\durable-252b3bfd
(JENKINS-48300: if on a laggy filesystem, consider -Dorg.jenkinsci.plugins.durabletask.BourneShellScript.HEARTBEAT_CHECK_INTERVAL=300)
I am not sure where to set this property.
I tried on Jenkins master -> Configure system -> Global properties -> Environment variables:
Name:org.jenkinsci.plugins.durabletask.BourneShellScript.HEARTBEAT_CHECK_INTERVAL
Value:300
But, I am not sure if this is the right place to add this property OR if it has come into effect.
Also, I haven't restarted the master or slave.
My jenkins set-up is Linux master (Jenkins ver. 2.107.1) and Linux and Windows Slaves.
My build is on a Windows slave (physical machine)
option 1:
Add in your pipeline
script {
System.setProperty("org.jenkinsci.plugins.durabletask.BourneShellScript.HEARTBEAT_CHECK_INTERVAL", "3800");
}
after Running the approve the script in security settings at Manage Jenkins – In-process Script approval.
Option 2:
go to Manage Jenkins -> Script Console
and run
System.setProperty("org.jenkinsci.plugins.durabletask.BourneShellScript.HEARTBEAT_CHECK_INTERVAL", "3800");

Note: you'll need to restart your Jenkins instance.
Edit: As per sirch's comment, I'm copying here the instructions for RedHat and Debian distro's.
Debian / Ubuntu based Linux distributions
If your configuration file is under /etc/default/ look for the argument JAVA_ARGS. It should look something like this:
JAVA_ARGS="-Djava.awt.headless=true"
Then, add the arguments:
JAVA_ARGS="-Xmx2048m -XX:MaxPermSize=512m -Djava.awt.headless=true"
RedHat Linux based distributions
If your configuration file is under /etc/sysconfig/ look for the argument JENKINS_JAVA_OPTIONS. It should look something like this:
JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true"
Then, add the arguments:
JENKINS_JAVA_OPTIONS="-Xmx2048m -XX:MaxPermSize=512m -Djava.awt.headless=true"
set it either
JAVA_OPTS
or
JNLP_PROTOCOL_OPTS
which will be included in jenkins slave Startup Options
I am trying to read the environment variables in Groovy Postbuild step. I am able to read the values of parameters passed to builds but unable to read the values of parameters which are set in one of my Execute Windows batch command.
In one example of my Execute Windows batch command I do this:
SET custom_param=myValue
if I use ${custom_param} in other jenkins steps/jobs, it gets my value. So I am sure it has the value. I just can't get it in groovy script
I have tried followings to do so, none of them have worked:
manager.envVars['custom_param']
build.buildVariableResolver.resolve('custom_param')
build.getEnvironment(listener).get('custom_param')
Any help here would be great
(Assuming you're not running your script in groovy sandbox)
Try the bellow:
build = Thread.currentThread().executable
String jobName = build.project.getName()
job = Hudson.instance.getJob(jobName)
my_env_var = job.getLastBuild().getEnvironment()["YOUR_ENV_VAR"]
Groovy Post build step run as separate process. It has access to environment as normal JVM process.
You could use EnvInject plugin as a a build step. Subsequent steps in build will able to read this via normal environment access (System.env in your groovy script)
When you set some custom variables in your "Windows command batch" step, these variables are available only during this Jenkins step.
Once Jenkins move on the next step, your variables are lost...
If you want to set some variables permanently, you can try to use the SETX command:
What is the difference between setx and set in environment variables in Windows?
I am running a Jenkins instance hosted by Cloudbees. I installed the Jenkins EnvInject plugin and I added a Pre-Build step. I added a variable under "Properties Content":
CERT_HOME=/private/{my-domain-name}/dev
The CERT_HOME path and actual certificates are under the WebDAV directory that Cloudbees provides.
In a JUnit test, I try to access the environment variable like this:
private static final String CERT_HOME = System.getenv("CERT_HOME");
However, it returns null.
Under the build, I do see the environment variable:
CERT_HOME=/private/{my-domain-name}/dev
How do I read an environment variable in my JUnit test that I set using the EnvInject plugin?
Maven surefire tries to give you a clean environment within the forked process, have a look at using environmentVariables with ${env.CERT_HOME} to try passing it through
In my nant script I retrieve my environment variable in this way:
property name="ProjectSolutionPath" value="${environment::get-variable('MAIN_PROJECT_PATH')}"
but when I run it through jenkins using nant as build step I got an error like this.
Expression: ${environment::get-variable('MAIN_PROJECT_PATH')}
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Environment variable "MAIN_PROJECT_PATH" does not exist.
Is there configuration for this? so that Jenkins will recognize environment variables access by my nant script?
Help is greatly appreciated.
Make sure you define this environment variable in "System variables".
Since the Jenkins process usually runs as "NT AUTHORITY\SYSTEM" user, the environment variables associated with your user account do not get appended to the env-vars of the process.
I've seen this answer on how to add env-vars to a Jenkins build (though I don't like spawning a cmd line process), if you do not want to use sys-env-vars.
