spring-projects's Issues

Running the sub module spring boot application in Intellij Idea

After migration to composite build. I was unable to run the spring application present in modules by executing main method.

Migrate module to project, for use with Gradle composite builds

Composite builds in gradle mean that an already working gradle project can be used as dependency within our own project.
The main difference between a multi module project and composite build project is there is a single project build in a multi module build, i.e, only one root build.gradle and settings.gradle file, however in case of composite builds existing gradle projects can be imported from the gradle menu available in Intellij idea, making the project is completely independent at the same time imports as modules, if required these modules can be added as dependencies to our project.

Add thymeleaf view module for the library application

This module should be responsible for having only the html views & templates.

Add as dependency to the library-management-application module

Configure a new module with h2 database

Create and configure a Sample subproject in gradle

Steps Taken

1. Create a SubProject "spring-boot-start" having the gradle configuration from the spring-initializer. To create a subproject, right click the root project and select new module, select gradle module and proceed.

2. Create allprojects block in the gradle file. Move dependencies, configurations to this block, so it is available to all the sub-projects, and itself under it.
   And apply needed plugins for use in sub-projects.
   

3. Including the projects in settings.gradle file located at root location.
   

Building Library Management Application from the root project

As spring-boot-start module is now a separate project in the root project.
So now the root project dont have any subprojects.
The spring-boot-start project is now independent and no tasks of it can be run from this composite build setup.

Solution
So, to fix this, we will create a task in root project which delegates to the task of sub module in spring-boot-start project.

Sample Task in root build.gradle should look like this

task buildLibraryManagementApp {
    dependsOn gradle.includedBuild('spring-boot-start').task(':library-management-application:build')
}

Create a gradle project using Spring Initializer

Steps Taken

1. Generate the project from https://start.spring.io/
   

2. Copy all files except the src folder, to the project location.
   

3. Project won't be detected as gradle project. Reimport the same from intellij. Closing the project and reopening it will show up the below popup, click on import gradle project.
