Update & Reschedule MS Project in Aspose.Tasks

Introduction

Microsoft Project is a widely-used project management software that allows users to manage tasks, resources, and timelines efficiently. Aspose.Tasks for Java provides a powerful set of APIs to manipulate Microsoft Project files programmatically. In this tutorial, we’ll learn how to update MS Project files and reschedule uncompleted work using Aspose.Tasks for Java.

Prerequisites

Before we begin, ensure you have the following:

  1. Java Development Kit (JDK) installed on your system.
  2. Aspose.Tasks for Java library. You can download it from here.
  3. Basic understanding of Java programming language.

Import Packages

First, import the necessary packages in your Java code:

import com.aspose.tasks.NullableBool;
import com.aspose.tasks.Prj;
import com.aspose.tasks.Project;
import com.aspose.tasks.SaveFileFormat;
import com.aspose.tasks.Task;
import com.aspose.tasks.TaskLink;
import com.aspose.tasks.TaskLinkType;
import com.aspose.tasks.TimeUnitType;
import com.aspose.tasks.Tsk;
import java.util.Calendar;

Step 1: Set up the Project

Initialize a new Project object and define tasks within it along with their durations and dependencies.

String dataDir = "Your Data Directory";
Project project = new Project();
// Define tasks and their durations
// ...
// Define task dependencies
// ...
// Save the initial project state
project.save(dataDir + "not_updated.xml", SaveFileFormat.Xml);

Step 2: Update Project Work

Update the project work to mark it as complete up to a certain date.

Calendar cal = Calendar.getInstance();
cal.set(2014, Calendar.JANUARY, 28, 17, 0, 0);
project.updateProjectWorkAsComplete(cal.getTime(), false);
// Save the updated project
project.save(dataDir + "updated.xml", SaveFileFormat.Xml);

Step 3: Reschedule Uncompleted Work

Reschedule any uncompleted work to start after a specified date.

cal.set(2014, Calendar.JANUARY, 28, 17, 0, 0);
project.rescheduleUncompletedWorkToStartAfter(cal.getTime());
// Save the rescheduled project
project.save(dataDir + "rescheduled.xml", SaveFileFormat.Xml);

Conclusion

In this tutorial, we’ve learned how to update MS Project files and reschedule uncompleted work using Aspose.Tasks for Java. This can be particularly useful in scenarios where project timelines need adjustment based on progress or changing priorities.
