El script de post-proceso puede examinar el registro de salida del paso y ejecutar mandatos en función del resultado. En el siguiente fragmento de código, scanner.register() registra las cadenas error at line y the value is con un motor de expresiones regulares y, a continuación, ejecuta mandatos si se encuentran esas cadenas. Una vez registradas todas las cadenas, llama a scanner.scan() en el registro de salida del paso línea por línea.

// 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.

// variable contains the line number where the match occurred, and the
// "line" variable is the full text of the line.

El segundo paso puede utilizar también esas propiedades en su script
de post-proceso. Por ejemplo, el siguiente script de post-proceso incluye la propiedad
Status del paso anterior en una propiedad
del segundo paso:{
properties.put("Step2Prop","New property");
properties.put("Status","OK");
properties.put("StatusOfPreviousStep","${p:Step1/Status}");
