<h3>The simplest way</h3>

You can use <a href="https://wiki.jenkins-ci.org/display/JENKINS/EnvInject+Plugin" rel="noreferrer">EnvInject plugin</a> to injects environment variables at build startup. For example:

<img src="https://i.stack.imgur.com/x1YWm.png" alt="Add key=value (bash OK!) under &#39;Build Environment&#39;-&gt;&#39;Inject environment variables to the build process&#39; -&gt; &#39;Properties Content&#39;">

<h3>How you know it's working</h3>

Try <a href="https://wiki.jenkins-ci.org/display/JENKINS/Environment+Script+Plugin" rel="nofollow noreferrer">Environment Script Plugin</a> (<a href="https://github.com/jenkinsci/environment-script-plugin" rel="nofollow noreferrer">GitHub</a>) which is very similar to <a href="https://wiki.jenkins-ci.org/display/JENKINS/EnvInject+Plugin" rel="nofollow noreferrer">EnvInject</a>. It allows you to run a script before the build (after SCM checkout) that generates environment variables for it. E.g.

<a href="https://i.stack.imgur.com/8t38I.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8t38I.png" alt="Jenkins Build - Regular job - Build Environment"></a>

and in your script, you can print e.g. <code>FOO=bar</code> to the standard output to set that variable.

Example to append to an existing <code>PATH</code>-style variable:

<pre><code>echo PATH+unique_identifier=/usr/local/bin
</code></pre>

So you're free to do whatever you need in the script - either <code>cat</code> a file, or run a script in some other language from your project's source tree, etc.

For some reason <code>sudo su - jenkins</code> does not log me to <code>jenkins</code> <a href="https://stackoverflow.com/a/38286755/432903">user</a>, I ended up using different approach.

I was successful setting the global env variables using using jenkins <code>config.xml</code> at <code>/var/lib/jenkins/config.xml</code> (installed in Linux/ RHEL) - without using external plugins.

I simply had to stop jenkins add then add <code>globalNodeProperties</code>, and then restart.

Example, I'm defining variables <code>APPLICATION_ENVIRONMENT</code> and <code>SPRING_PROFILES_ACTIVE</code> to <code>continious_integration</code> below,

<pre><code>&lt;?xml version='1.0' encoding='UTF-8'?&gt;
&lt;hudson&gt;

 &lt;globalNodeProperties&gt;
 &lt;hudson.slaves.EnvironmentVariablesNodeProperty&gt;
 &lt;envVars serialization="custom"&gt;
 &lt;unserializable-parents/&gt;
 &lt;tree-map&gt;
 &lt;default&gt;
 &lt;comparator class="hudson.util.CaseInsensitiveComparator"/&gt;
 &lt;/default&gt;
 &lt;int&gt;2&lt;/int&gt;
 &lt;string&gt;APPLICATION_ENVIRONMENT&lt;/string&gt;
 &lt;string&gt;continious_integration&lt;/string&gt;
 &lt;string&gt;SPRING_PROFILES_ACTIVE&lt;/string&gt;
 &lt;string&gt;continious_integration&lt;/string&gt;
 &lt;/tree-map&gt;
 &lt;/envVars&gt;
 &lt;/hudson.slaves.EnvironmentVariablesNodeProperty&gt;
 &lt;/globalNodeProperties&gt;
&lt;/hudson&gt;
</code></pre>

We use groovy job file:

<pre><code>description('')
steps {
 environmentVariables {
 envs(PUPPETEER_SKIP_CHROMIUM_DOWNLOAD: true)
 }
}
</code></pre>

I would like to be able to do something like:

<pre><code>AOEU=$(echo aoeu)
</code></pre>

and have Jenkins set <code>AOEU=aoeu</code>.

The Environment Variables section in Jenkins doesn't do that. Instead, it sets <code>AOEU='$(echo aoeu)'</code>.

How can I get Jenkins to evaluate a shell command and assign the output to an environment variable?

Eventually, I want to be able to assign the executor of a job to an environment variable that can be passed into or used by other scripts.

How to set environment variables in Jenkins?

我希望能够做到以下几点：AOEU=$(echo aoeu)让Jenkins设置AOEU=aoeu。Jenkins中的环境变量部分没有做到这一点。相反，它设置AOEU='$(echo aoeu)'。如何让Jenkins评估shell命令并将输出分配给环境变量？最终，我希望能够将作业的执行者分配给一个环境变量，该变量可以传递给其他脚本或由其他脚本使用。
