 Now that your `Application` class is ready, you simply instruct the build system to create a single, executable jar containing everything. This makes it easy to ship, version, and deploy the service as an application throughout the development lifecycle, across different environments, and so forth.
 
-Add the following configuration to your existing Maven POM:
-
-`pom.xml`
-```xml
-    <properties>
-        <start-class>hello.Application</start-class>
-    </properties>

+Add the following configuration to your existing Gradle build file:
 
-The `start-class` property tells Maven to create a `META-INF/MANIFEST.MF` file with a `Main-Class: hello.Application` entry. This entry enables you to run it with `mvn spring-boot:run` (or simply run the jar itself with `java -jar`).

+The [Spring Boot gradle plugin][spring-boot-gradle-plugin] collects all the jars on the classpath and builds a single "über-jar", which makes it more convenient to execute and transport your service.
+It also searches for the `public static void main()` method to flag as a runnable class.
 
 Now run the following command to produce a single executable JAR file containing all necessary dependency classes and resources:
 
 ```sh
-$ mvn package
+$ ./gradlew build
+```
+
+Now you can run the JAR by typing:
+
+```sh
+$ java -jar build/libs/gs-rest-service-0.1.0.jar
