CLI generating modularized Gradle projects based on different shapes

If you need to create small or medium projects (<300 modules), you can use the web generator: https://cdsap.github.io/ProjectGenerator/

Usage

CLI

Install

curl -L https://github.com/cdsap/ProjectGenerator/releases/download/v0.3.8/projectGenerator  --output projectGenerator
chmod 0757 projectGenerator

Modes

1. Generate Project (default)

./projectGenerator generate-project --modules 100

This command generates a project with the specified shape, layers, and modules. All options below can be combined with this mode.

2. Generate YAML Versions File

./projectGenerator generate-yaml-versions

This command generates a versions.yaml file template for custom dependency versions. Then, you can use the versions.yaml in the generate-project command:

./projectGenerator generate-project --shape triangle --layers 5 --modules 100 --versions-file versions.yaml

CLI Options

• --shape: triangle, rhombus, flat, rectangle, middle_bottleneck, inverse_triangle (default: rectangle)
• --modules (required): Number of modules to create
• --layers: Number of layers (default: 5)
• --language: kts (default), groovy, both
• --type: android (default), jvm
• --classes-module: Number of classes per module (default: 5)
• --classes-module-type: fixed (default), random
• --type-of-string-resources: normal (default), large
• --generate-unit-test: Generate unit tests (default: false)
• --gradle: gradle_8_13, gradle_8_14_3, gradle_9_0_0, gradle_9_1_0, gradle_9_2_0 (default: gradle_9_2_0)
• --develocity: Enables the Develocity build scan plugin (default: false). If --develocity-url is not specified, the build scan will be published to Gradle Scans.
• --develocity-url: Specify Develocity URL
• --versions-file: Path to a custom YAML file with dependency versions
• --project-name: Name of the project
• --agp9: Use AGP 9.x (default: false). Only for Android projects.

Example: Generate a project with custom options

./projectGenerator generate-project --shape rhombus --modules 50 --layers 4 --language both --type jvm --classesModule 10 --classesModuleType random --typeOfStringResources large --generateUnitTest --gradle gradle_8_9 --develocity --versionsFile ./my_versions.yaml

Library

val modules = 50
val shape = Shape.RHOMBUS
ProjectGenerator(
    modules = 50,
    shape =shape,
    language = Language.KTS,
    typeOfProjectRequested = TypeProjectRequested.ANDROID,
    classesPerModule = ClassesPerModule(ClassesPerModuleType.FIXED, 20),
    versions = Versions(project = Project(jdk = "17")),
    typeOfStringResources = TypeOfStringResources.LARGE,
    layers = 5,
    generateUnitTest = true,
    gradle = GradleWrapper(Gradle.GRADLE_9_2_0),
    path = file.path
).write()

Dependency

  implementation("io.github.cdsap:projectgenerator:0.3.8")

Options

modules

Number of modules to create in the project

layers

Number of layers where the modules will be distributed.

shape

Defines the shape of the project dependency graph based on the distribution of modules by layer. When generating a new project, a graph.dot file is created in the root project folder containing the project dependency graph. Current shapes supported:

triangle

inverse_triangle

rhombus

rectangle (default)

flat

middle_bottleneck

language

kts

default

The project generated includes modules build scripts in Kotlin DSL

groovy

The project generated includes modules build scripts in Groovy

both

Two projects will be generated using Kotlin DSL and Groovy

Example

./projectGenerator  generate-project  --shape triangle --layers 5 --modules 100 --language groovy

type

Type of project generated:

android

default

Android project

jvm

Kotlin-JVM project

Example

./projectGenerator  generate-project  --shape triangle --layers 5 --modules 100 --type jvm

Classes Module

Classes generated per module, options:

• classes: Classes to generate per module. Default 5.
• type:
  • Fixed(default): Each module will create n classes where n represents the argument classes.
  • Random: Each module will create Random.nextInt(2, classesPerModule.classes) classes.

Example

./projectGenerator  generate-project  --shape triangle --layers 5 --modules 100 --classes-module-type random --classes-module 150

String Resources type

Normal

Each module generated includes 8 string resources in the file strings.xml. Default.

Large

Each module generated includes 900 string resources in the file strings.xml

Example

./projectGenerator  generate-project  --shape triangle --layers 5 --modules 100 --type-of-string-resources large

Generate Unit Test

default false

If enabled, each module will generate n unit tests, where n is the argument classes

Example

./projectGenerator  generate-project  --shape triangle --layers 5 --modules 100 --generate-unit-test true

Gradle

Gradle used, versions supported:

• Gradle 8.5
• Gradle 8.9
• Gradle 8.13
• Gradle 8.14_2
• Gradle 9.0.0 default

Example

./projectGenerator  generate-project  --shape triangle --layers 5 --modules 100 --gradle 8.13
