Hi in my jenkinsFile I want to iterate over a properties file, but I always get an error how can it be done properly with no error?
node('master') { Properties properties = new Properties() properties.load(new FileInputStream("${env.JENKINS_HOME}\\properties\\${file}")) for(Entry<Object, Object> en : properties.entrySet()) { System.out.println(en); } /*for(Object k:properties.keySet()) { String key = (String) k; } */ // same error /* Enumeration en = properties.propertyNames(); while (en.hasMoreElements()) { String key = (String) en.nextElement(); System.out.println(key + " -- " + properties.getProperty(key)); }*/ // same error } java.io.NotSerializableException: java.util.Hashtable$Entry at
