Gradle Bootrun Example

BootRun (Spring Boot Gradle Plugin 2.3.2.RELEASE API), The bootRun task can be simply configured in build.gradle. For example, we can define the main class: bootRun. Main Spring boot Gradle contains task bootRun which help us to compile and run spring boot application: Go to the root of the application where build.gradle is available Run.

Getting Started, In this post we create a Hello World Spring Boot Application using Gradle build tool. Video. This tutorial is explained in the below Youtube Video. Lets Begin-. If Spring Boot Tutorial-Spring Boot+ Gradle. In this post we create a Hello World Spring Boot Application using Gradle build tool. Video.

  1. For example, if we were building a WAR file, a format commonly associated with packing in 3rd party dependencies, we could use gradle’s WAR plugin. If you are using Spring Boot and want a runnable JAR file, the spring-boot-gradle-plugin is quite handy. At this stage, gradle doesn’t know enough about your system to make a choice.
  2. For example mine is 192.168.99.100, I'm using this instead of 192.168.59.103 that's in the example., If you'd like to use the bootRun command make sure you are running it against the build.gradle in the core module like this (the properties file only works with an absolute path for me).
  3. The Spring Boot Gradle plugin also includes a bootRun task that can be used to run your application in an exploded form. The bootRun task is added whenever you apply the org.springframework.boot and java plugins and is shown in the following example.

I've tried shadow, gradle-fatjar-plugin, gradle-one-jar, spring-boot-gradle-plugin plugins but neither of them adds my dependencies declared as implementation (I don't have any compile ones).

Spring boot multi module gradle

Getting Started, An example of using the Gradle Kotlin DSL for a multi-module Spring project. Creating a Multi Module Project This guide shows you how to create a multi-module project with Spring Boot. The project will have a library jar and a main application that uses the library. You could also use it to see how to build a library (that is, a jar file that is not an application) on its own.

Building a Multi-Module Spring Boot Application with Gradle, In your utility (data) projects put: bootJar { enabled = false } jar { enabled = true }. If kotlin dsl tasks.getByName<BootJar>('bootJar') { enabled This is how to use Gradle + Spring Boot Gradle Plugin in multiple module configuration. Gradle Root Module In the build.gradle on the Root Module side, Write “bootJar.enabled = false” and “jar.enabled = true”. plugins { id 'org.springframework.boot' version '2.0.3.RELEASE' } bootJar.enabled = false jar.enabled = true Sub Module We just add the Sub Module to the dependencies without considering anything. plugins { id 'org.springframework.boot' version '2.0.3.RELEASE' } .

My Gradle project structure looks like this: My project. Application; module1 api; domain; repository; module2 sames as module1; the Application module has dependencies on each module project and implementation group: 'org.springframework.boot', name: 'spring-boot-starter', version: springBootVersion. on API submodule there is:

Gradle build jar

Building Java Libraries, In this tutorial, we will show you how to use Gradle build tool to create a single Jar file with dependencies. Tools used : Gradle 2.0; JDK 1.7 Gradle uses a convention-over-configuration approach to building JVM-based projects that borrows several conventions from Apache Maven. In particular, it uses the same default directory structure for source files and resources, and it works with Maven-compatible repositories.

Building Java & JVM projects, An executable jar file is just a jar file containing a Main-Class entry in its manifest. So you just need to configure the jar task in order to add this A build.gradle sample to create a Jar file along with its logback dependencies. build.gradle. apply plugin: 'java' apply plugin: 'eclipse' version = '1.0' sourceCompatibility = 1.7 targetCompatibility = 1.7 //create a single Jar with all dependencies task fatJar (type: Jar) { manifest { attributes 'Implementation-Title': 'Gradle Jar File Example', 'Implementation-Version': version, 'Main-Class': 'com.mkyong.DateUtils' } baseName = project.name + '-all' from { configurations.compile.

Getting Started, Let's start with modifying the jar task from the Java Gradle plugin. By default, this task produces jars without any dependencies. We can overwrite $ jar tf build/libs/demo.jar META-INF/ META-INF/MANIFEST.MF demo/ demo/Library.class You should see the required manifest file — MANIFEST.MF — and the compiled Library class. All of this happens without any additional configuration in the build script because Gradle’s java-library plugin assumes your project sources are arranged in a conventional project layout .

1. Introduction

Gradle Spring Boot Run Example

Spring Boot is a framework to build Java applications with minimal boilerplate code required, whereas Gradle is a highly configurable build automation tool.

Using Gradle to build your Spring Boot application is a good approach, but the process is made infinitely easier using the Spring Boot Gradle plugin to provide build functionality specific to Spring Boot.

In this article, we’ll explore the most common uses case to get up and running with the Spring Boot Gradle plugin, as well as how to customise it to meet your specific requirements.

2. Applying the plugin

Simply add the latest version of the Spring Boot Gradle plugin to the plugins declaration in your build.gradle file, like this:

Note that the version of the plugin applied here corresponds directly to the version of Spring Boot that you’re targeting.

This on its own doesn’t add anything to your build. Instead, the Spring Boot Gradle plugin is reactive, meaning that its behaviour changes depending on what other plugins you have applied.

Reacting to the java plugin

Let’s also add the java plugin. This core Gradle plugin provides Java compilation and testing capabilities to your project. Chances are, if you already have a Spring Boot project, you’ll have the java plugin. It’s applied like this:

Now things get a bit more interesting. ✅ The Spring Boot plugin reacts to the java plugin by adding:

  • a bootJar task which builds a fat jar containing everything required in order to run your application standalone
  • a bootRun task which starts your application
  • some configuration and wiring, including
    • disabling the jar task, as it’s replaced by bootJar
    • hooking up the bootJar task to run whenever the Java plugin’s assemble task runs

bootJar task

Our task graph for the assemble task now looks like this:

Task graphs
In Gradle tasks are linked together in a graph structure. If we have two tasks, A and B, task A can be configured to depend on task B. This means that whenever we run task A, task B will be run first. You can view the task graph using the task-tree plugin.

This means that whenever you run ./gradlew assemble (or build) the fat jar for your application will get created with the bootJar task:

The fat jar gets output to build/libs/<project-name>-<project-version>.jar.

bootRun task

The task graph for the bootRun task is this:

If we grun ./gradlew bootRun the plugin will look for a class with a public static void main(String[] args) method. In a Spring Boot application this is typically a class which is annotated with @SpringBootApplication, which when run starts the application.

We’ll see output like this, telling us that the application has started successfully:

If you have multiple classes with public static void main(String[] args) methods, you can configure which one to use like this:

Reacting to the war plugin

The war plugin extends the java plugin. Rather than generating the jar file, you’ve guess it, it generates a war file instead.

The Spring Boot Gradle plugin reacts to this plugin by creating the bootWar task, which generates an executable fat war file similar to the jar.

bootWar task

The task graph for the bootWar task looks like this:

If we run ./gradlew assemble now the fat war will get created through the bootWar task:

The fat war gets output to build/libs/<project-name>-<project-version>.war.

war vs. jar
The contents of these two files are very similar. However, they differ in structure since the war file contains a WEB-INF directory and the jar a BOOT-INF. They are both executable with java -jar <file-name>. But, with some small changes to your configuration the war file can also be deployed to a standalone Tomcat instance.

3. Declaring Spring Boot dependencies without the version number

If you also apply the io.spring.dependency-management plugin then the Spring Boot Gradle plugin will import the spring-boot-dependencies BOM (or the bill of materials) for whatever version of Spring you’re targeting:

This means that the plugin will know what versions of Spring Boot dependencies to bring in, so you don’t have to declare the versions yourself. It derives the Spring Boot version from the version of the Spring Boot plugin that you’ve applied, which in this case will be 2.2.6.RELEASE.

Dependencies can then be declared in short form like this:

4. Adding build info

Encore music notation free download. Spring Boot actuator endpoints provide a way to monitor your application. The /actuator/info endpoint, according to the docs:

Displays arbitrary application info.

By default if you hit localhost:8080/actuator/info you’ll see this:

Not much fun to be had here. 🥱 Let’s fix this by getting the Spring Boot Gradle plugin to include build information by adding this configuration to build.gradle:

Now the same URL returns this:

You can see that the plugin has chosen sensible defaults for all these fields. Any of them can be overridden using the properties configuration, like this:

Which now returns:

Spring Boot magicexplained
The Spring Boot Gradle plugin generates a build/resources/main/META-INF/build-info.properties file which Spring Boot loads onto the info endpoint automatically

5. Publishing

Eventually once you’re happy with your jar or war file, you’ll want to publish it. The maven-publish plugin allows you to publish Gradle built artifacts to a Maven repository.

We can use outputs from the bootJar (or bootWar) task like this, by passing the task to the artifact method:

Now we can run ./gradlew publish -PmavenUser=<user> -PmavenPassword=<password> and see that our jar file has been published:
