Running Java applications

If we want to execute a Java executable from a Gradle build, we have several options. Before we explore these options, we will first create a new Java class with a main() method in our project. We will execute this Java class from our build file.

In the directory src/main/java/gradle/sample, we need to create a new file The following code listing shows the contents of the file. We use our Sample class to print the value of the getWelcomeMessage() method to System.out:

// File: src/main/java/gradle/sample/
package gradle.sample;

import java.util.ResourceBundle;

public class SampleApp {

    public SampleApp() {

    public static void main(final String[] arguments) {
        final SampleApp app = new SampleApp();

    public void welcomeMessage() {
        final String welcomeMessage = readMessage();

    private String readMessage() {
