     // of the script called by the plug-in step. Typically, if the value of
     // the exitCode property is non-zero, the plug-in step failed.

          // Register a scanner to search for the text "error at line" in the log.
          // The first argument is a regular expression.
          //
          // The second argument, an inline function, is invoked once for
          // every line in the log output that matches the pattern. The "lineNumber"
          // variable contains the line number where the match occurred, and the
          // "line" variable is the full text of the line.
          //
          scanner.register("(?i)ERROR at line",  function(lineNumber, line) {

              //
              // In this case, we build up an "Error" property which
              // contains the text of all errors that are found. We find every
              // line starting with "error at line" and add it to this list.
              //
              errors.put("Errors", errorString);


              //
              // If a line starting with "error at line" is found, the step has
              // failed, so we set the special "Status" property to "Failure",
              // indicating to the UrbanCode Deploy server that the step should
              // be marked as a failure.
              //
              properties.put("Status", "Failure");
          });
         
          //
          // Multiple searches can be registered with the scanner. We add a
          // second search to look for some interesting text to set as an output
          // property.
          //
          // For example, if there is a line "The value is BLUE", then we end up
          // with an output property, "Value", with a value of "BLUE".
          //
          scanner.register("The value is", function(lineNumber, line) {
              var value = line.replace("The value is ", "");
              properties.put("Value", value);
          });
         
          scanner.scan();


          //
          // Convert the collected list of error strings into a single string and
          // set that as an output property.
          //
          var errors = properties.get("Error");
          if (errors == null) {
              errors = new java.util.ArrayList();
              properties.put("Error", errors);
          }
          properties.put("Error", errors.toString());
     }

if (properties.get("exitCode")==0)
  { properties.put("Status","Success"); }
else
  { properties.put("Status","Failure"); }

properties.put("Step1Prop","value1");

echo Properties of previous step:
echo "${p:Step1/Status}"

1. In the first step, store the value in a place where the post-processing script can access it. You can store the value by writing it to the log file for the step. For example, if you are using a Shell step, you can write the value and a unique key to the log with an echo command:

   echo "myvalue=1234"

   As a result, the log for the step shows the key and value:

   myvalue=12345

2. In the post-processing script for the step, use the scanner object to scan the log for the key. Then, assign the value to an output parameter. The following example script searches the output log for the key myvalue= and then stores the value in the output property myOutputValue:

   var exit = properties.get('exitCode');
   
   scanner.register("my value=", function(lineNumber, line) {
        var value=line.replace("my value=","");
        properties.put("myOutputValue",value);
   });
   
   if (exit == 0) {
       properties.put('Status', 'Success');
   }
   else {
        properties.put('Status', 'Failure');
   }
   scanner.scan();

3. In future steps, refer to the output parameter of the first step. For example, if the first step is named SetMyValue, future steps can refer to the property with the following code:

   ${p:SetMyValue/myOutputValue}
