title: How to set Environment variable option while running JAR?
body: <p>I have a <code>JAR</code> which accepts environment variable options. When I run the main class manually by setting run configuration, I provide environment variable as : <code>KERBOROS_KEYTAB_LOC="location of the keytab file"</code></p>
  
  <p>Now I need to set these options while running the <code>JAR</code>. How I can set that? I tried below option but it is not working.</p>
  
  <pre><code>java -DKERBOROS_KEYTAB_LOC="location of the keytab file" -jar jarfile.jar
  </code></pre>
