Stop and Resume Resource Assignments in Aspose.Tasks

Introduction

In this tutorial, we will learn how to stop and resume resource assignments using Aspose.Tasks for Java. Aspose.Tasks is a powerful Java API that allows developers to work with Microsoft Project files without needing Microsoft Project installed on their systems. We’ll break down the process into manageable steps to make it easy to follow along.

Prerequisites

Before we begin, ensure you have the following prerequisites:

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

Import Packages

First, let’s import the necessary packages into our Java project:

import com.aspose.tasks.Asn;
import com.aspose.tasks.Project;
import com.aspose.tasks.ResourceAssignment;
import java.util.Calendar;
import java.util.GregorianCalendar;
import java.util.Objects;

Step 1: Load the Project File

// The path to the documents directory.
String dataDir = "Your Data Directory";
// Load the project file
Project prj = new Project(dataDir + "ResourceAssignmentVariance.mpp");

In this step, we load the project file into a Project object using the file path.

Step 2: Iterate Through Resource Assignments

// Define minimum date
java.util.Date minDate = new GregorianCalendar(2000, Calendar.JANUARY, 1).getTime();
// Iterate through resource assignments
for (ResourceAssignment ra : prj.getResourceAssignments()) {

Here, we define a minimum date and start iterating through each resource assignment in the project.

Step 3: Check Stop and Resume Dates

    // Check stop date
    if (ra.get(Asn.STOP).before(minDate)) {
        System.out.println("NA");
    } else {
        System.out.println(ra.get(Asn.STOP));
    }
    // Check resume date
    if (ra.get(Asn.RESUME).before(minDate)) {
        System.out.println("NA");
    } else {
        System.out.println(ra.get(Asn.RESUME));
    }
}

In this step, we check if the stop and resume dates of each resource assignment are before the minimum date. If they are, we print “NA”, otherwise, we print the respective dates.

Conclusion

In this tutorial, we’ve learned how to stop and resume resource assignments in Aspose.Tasks for Java. By following the provided steps, you can easily implement this functionality in your Java projects.
