Custom Stack - Project Structure

Overview

This section shows how to create the project structure of the Custom Stack. It contains the creation of several Maven pom.xml files, static content resources, application.properties configuration files and a Spring Boot Java class.

Prerequisites

JDK 21+ - OpenJDK versions can be found here.
Maven 3.5+ - Maven version 3.5.3 can be found here.

Steps

Create Maven Project

Create new folder on your machine, for the custom stack (e.g. <my-custom-stack-path>/custom-stack).
Create pom.xml and application/pom.xml files.

pom.xmlapplication/pom.xml

Create new pom.xml file.
Paste the following content:

pom.xml

Eclipse Dirigible version

The tutorial is using Eclipse Dirigible version 10.2.7 as highlighted on line 229. To check for a more recent and stable version go to Eclipse Dirigible Releases.

Create new folder application and navigate to it.
Create new application/pom.xml file.
Paste the following content:

application/pom.xml

Git Repository

For git repositories uncomment the following lines, in order to receive the Commit Id information in the About view:

<!-- 
    Note: Uncomment for git repositories, as this plugin would get the last commit id.
    This is needed for the info in the "About" view.

Create Eclipse Dirigible Resources

Navigate to the application folder.
Create src/main/resources/ folder structure and navigate to it.
Create dirigible.properties, index.html and index-busy.html files.

dirigible.propertiesstatic/index.htmlstatic/index-busy.html

Create application/src/main/resources/dirigible.properties file.
Paste the following content:

application/src/main/resources/dirigible.properties

# General
DIRIGIBLE_PRODUCT_NAME=${project.title}
DIRIGIBLE_PRODUCT_VERSION=${project.version}
