Step 2: Create a Module

We have created the application project successfully in previous step. Now the real functionalities should be added by creating modules.

Create a module

A module is again a gradle sub project. Typically created inside modules directory. However, you can use any directory structure. See gradle multi-project builds documentation for more details.

In this section, we will see how to create a simple axelor-contact module. This demo module defines some objects for managing contacts.

Create a new directory modules/axelor-contact inside application project and create module build script like this:

plugins {
  id '' (1)

axelor { (2)
  title = 'Axelor Contact'
1 The gradle plugin for module project
2 The module project configuration

That’s it. You have successfully created your first module.

Let’s check the build.gradle script:

The plugin defines an extension point axelor where we can define various properties.

  • title - display title for the module

  • description - a short description about the module

Update application project

Now as we have the module ready, we have to utilize it in the build process. So we have to include the module to the settings.gradle of the application project.

// Include modules
include "modules:axelor-contact"

And the application is using this module, so the build.gradle has to be updated like this:

dependencies {
  compile project(':modules:axelor-contact')

Now check whether the project is configured properly, build it again:

$ ./gradlew build

The build should complete without any error.

What’s next?

Still we have only created bare module and it doesn’t provide any functionalities yet. In the next step, we’ll see how to add domain entities.
