I found this groovy script to create a global environment variable in
Jenkins.
Env.groovy:
import hudson.EnvVars;
import hudson.slaves.EnvironmentVariablesNodeProperty;
import hudson.slaves.NodeProperty;
import hudson.slaves.NodePropertyDescriptor;
import hudson.util.DescribableList;
import jenkins.model.Jenkins;
public createGlobalEnvironmentVariables(String key, String value){
Jenkins instance = Jenkins.getInstance();
DescribableList<NodeProperty<?>, NodePropertyDescriptor>
globalNodeProperties = instance.getGlobalNodeProperties();
List<EnvironmentVariablesNodeProperty> envVarsNodePropertyList =
globalNodeProperties.getAll(EnvironmentVariablesNodeProperty.class);
EnvironmentVariablesNodeProperty newEnvVarsNodeProperty = null;
EnvVars envVars = null;
if ( envVarsNodePropertyList == null ||
envVarsNodePropertyList.size() == 0 ) {
newEnvVarsNodeProperty = new
hudson.slaves.EnvironmentVariablesNodeProperty();
globalNodeProperties.add(newEnvVarsNodeProperty);
envVars = newEnvVarsNodeProperty.getEnvVars();
} else {
envVars = envVarsNodePropertyList.get(0).getEnvVars();
}
envVars.put(key, value)
instance.save()
}
createGlobalEnvironmentVariables('xyzabc','baymac')
Using Jenkins CLI with the command to execute the above script
java -jar "jenkins-cli.jar" -s 'https://my.jenkins.instance' -noKeyAuth -auth
".jenkins-cli-auth" groovy = <
where .jenkins-cli-auth is `<User ID>:<API Token>`
The env variables are populated

Now the question is, is it a good idea to recommend users to populate env
with GitLab Personal Access Token using this method before performing a
jcasc reload?
Also I think it would be better to store env variables values in a password
form rather than plain text.
