如何从测试用例中的jenkins获取环境变量列表

Question

I am creating a test case for a plugin, I want to fetch all the environment variables that are present on the current Jenkins server. Can anyone tell me how to fetch all the environment variables from the Jenkins server?

   public class VariableExistsConditionTest {

    @Rule public JenkinsRule j = new JenkinsRule(); 


     @Test
      public void someTest() throws IOException, InterruptedException {
         EnvironmentVariablesNodeProperty prop = new EnvironmentVariablesNodeProperty();
         EnvVars env = prop.getEnvVars();
         env.put("DEPLOY_TARGET", "staging");
         j.jenkins.getGlobalNodeProperties().add(prop);
        //Code to fetch the environment variables


}

To get all environment variables use

Map<String, String> env = System.getenv();
