Sling Template through Maven Archetype

Introduction

This archetype will create a Sling project that can be deployed on the Sling 9. In contrast to the Apache Sling Maven Archetypes this one is geared towards creating a full project and not just a single module.

The core and ui.apps are empty Maven modules that are ready for you code.

There are also example modules with the extension of .exmaple. Please copy whatever you want from these module into the appropriate module. The example modules are not intended to be installed into Sling. Both type (regular and example) have the same structure and so you can copy them over without any problems.

If this archetype was generated with the optionAll property set to y then an all package will be created that contains both the core and the ui.apps. This enables the developer to easily deploy all modules in that project to deployed as a single unit (see below).

If this archetype was generated with the optionAll property set to n then the core bundle will be deployed as embedded bundle of the ui.apps package.

Why a Separate All Package

For a simple project that only contains one or two modules (bundle and content package) this seems like overkill and the same can be accomplished using the ui.apps as single deployment package.

That said for a more serious project where there are multiple bundles and content packages this becomes difficult to handle. Not only needs one Content Package to take the role of the single deployment package which requires it to add the other modules as dependencies. This can be confusing and so the dedicated All content package solves that. It contains the dependencies and the logic how to build and deploy the entire project in one step.

Archetype Properties

packageGroup	Name of the Package Folder where the ui.apps is installed in (/etc/packages)
appsFolderName	Folder name under /apps where components etc are installed
contentFolderName	Folder name under /content where the content is added to
package	Root Package of the Java Code
slingModelSubPackage	Sub Package where Sling Models should be place in with no trailing dots
slingHostName	Host Name or IP Address of the server where Sling is hosted
slingPort	Port to which your Sling instance is bound to
optionAll	Determines if the project is created with an all package as single deployed unit (y/n)
optionExample	Determines if the examples are kept separate (s), merged into the regular modules (m) or deleted (d)

Usage

Until this project is fully released in the public Maven Repo this is how to use it:

• Build this project locally

  mvn clean install

• Go to your folder where you want your generated project to be

• Generate it with:

  mvn archetype:generate -DarchetypeCatalog=local

• Select this Archetype from a given list

• Provide the requested properties

Build and Install Integration Test

There is a simple integration test setup with this archetype. You can run this one using the attached Unix shell script:

sh build.run.and.deploy.test.sh

The properties for the integration test can be found under /test/resources/projects/[all/notAll]/archetype.properties.
