Hello World - Project 0002

This repository contains a simple "Hello World" project setup using Java and Gradle.

Project Structure

  • src/main: Contains the main Java source files.
  • src/test: Contains test files.
  • gradle/wrapper: Contains the Gradle wrapper for build automation.
  • scripts/: Contains Groovy scripts for model generation.

Groovy Generators

The Groovy scripts in the scripts folder are used for generating code models automatically. These scripts simplify the process of creating repetitive or template-based code structures within the project.

the main script is generator.java.groovy

it accepts two parameters : 1 - the generator plugin that will be used for source code generation 2 - the relative path of a POJO that describes the entity that will generate source code.

when using inmem_repository and/or csv_repository the POJO fields should be annotated with @MagicCsv* to convey the info oabout the de/-serializers, the fields participating at the unique key or whether the field should be ignored if these annotations are not present the generated code could be faulty ( since there's no primary key ) ... so add @MagiCsvId to at least one of the POJO's fields.

the files will be generated in the POJO's package, you can move them around in intellij or vscode with ease ( it'll count as refactoring ) examples
