後處理 Script 可以檢查步驟的輸出日誌,並根據該結果執行指令。在下列程式碼片段中,scanner.register() 會使用正規表示式引擎登錄字串 error at line 及 the value is,並在找到那些字串時執行指令。登錄所有字串之後,它會在步驟輸出日誌上逐行呼叫 scanner.scan()。
properties.put("Status", "Success");
//
// Evaluate the built-in exitCode property, which indicates the exit code
// 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.
//
if (properties.get("exitCode") != 0) {
properties.put("Status", "Failure");
}
else {
//
// 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.
//
var errors = properties.get("Error");
if (errors == null) {
errors = new java.util.ArrayList();
}
errors.add(line);
//
// 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");

第二個步驟也可以在其後處理 Script 中使用那些內容。例如,下列後處理 Script 在第二個步驟內容中包括前一個步驟的 Status 內容:{
properties.put("Step2Prop","New property");
properties.put("Status","OK");
properties.put("StatusOfPreviousStep","${p:Step1/Status}");
}
