Large Class Build Run

A Doma framework test project for benchmarking build performance with large numbers of classes.

Overview

This project is designed to test the build performance of Doma's annotation processor by automatically generating 200+ DAO interfaces and entity classes. It includes comprehensive test suites for all generated DAOs to verify the functionality of batch operations and aggregate strategies.

Requirements

• Java 17 or higher
• Gradle 8.5 or higher

Setup

# Clone the repository
git clone https://github.com/domaframework/large-class-build-run.git
cd large-class-build-run

# Build the project
./gradlew build

Usage

Basic Commands

# Build the project
./gradlew build

# Run the application
./gradlew run

# Run tests
./gradlew test

# Clean build artifacts
./gradlew clean

Code Generation

Commands to generate large numbers of test classes:

# Generate all DAO, entity, and SQL files (default: 200 classes)
./gradlew generateAll

# Generate only DAO classes
./gradlew generateDAOs

# Generate only entity classes
./gradlew generateEntities

# Generate only SQL files
./gradlew generateSqlFiles

# Generate test classes for all DAOs
./gradlew generateTests

# Remove all generated files
./gradlew removeGeneratedFiles

The number of generated classes can be modified by changing the generationSize variable in build.gradle.kts.

Code Formatting

# Format code using Google Java Format
./gradlew spotlessApply

# Check code formatting
./gradlew spotlessCheck
