Replace gradle.properties with ModConfig object for IDE completion support

[Copilot]

Eliminates gradle.properties dependency for mod configuration by defining all mod and environment settings directly in build.gradle.kts using a ModConfig object, providing full IDE completion support and type safety.

Problem

The current build.gradle.kts manually declares each property from gradle.properties using by project delegation, resulting in verbose and repetitive code:

val mod_version: String by project
val mod_group_id: String by project
val mod_id: String by project
val minecraft_version: String by project
// ... 10+ more similar declarations

This approach requires maintaining mod configuration in a separate gradle.properties file and doesn't provide IDE completion support for the configuration values.

Solution

Replaced the gradle.properties dependency for mod configuration with a self-contained ModConfig object that defines all configuration directly in the build script:

object ModConfig {
    // Environment Properties
    const val minecraftVersion = "1.20.1"
    const val minecraftVersionRange = "[1.20.1,1.21)"
    const val forgeVersion = "47.4.0"
    const val forgeVersionRange = "[47.4,)"
    const val loaderVersionRange = "[47,)"
    const val mappingChannel = "parchment"
    const val mappingVersion = "2023.09.03-1.20.1"
    
    // Mod Properties
    const val modId = "examplemod"
    const val modName = "Example Mod"
    const val modLicense = "MIT"
    const val modVersion = "0.1.0"
    const val modGroupId = "io.github.meatwo310.examplemod"
    const val modAuthors = "Meatwo310"
    const val modDescription = ""
}

// Usage with full IDE completion:
version = "v${ModConfig.modVersion}"
group = ModConfig.modGroupId

The gradle.properties file is now streamlined to contain only essential Gradle JVM settings:

org.gradle.jvmargs=-Xmx3G
org.gradle.daemon=false

Benefits

• Full IDE Completion: Type ModConfig. to get complete autocomplete list of all properties
• Streamlined Configuration: gradle.properties now only contains essential Gradle settings
• Type Safety: Compile-time validation of all configuration values using const val
• Better Organization: All configuration grouped logically with clear comments
• Self-Documenting: Configuration structure immediately visible in build script
• Refactoring Support: IDE can safely rename/refactor properties across entire project
• Single Source of Truth: All mod configuration centralized in build script

Changes Made

• Moved all mod and environment configuration from gradle.properties to ModConfig object
• Created ModConfig object with all 14 configuration properties as const val
• Updated all property usages throughout the build script to use ModConfig references
• Organized properties into logical groups (Environment Properties and Mod Properties)
• Cleaned up gradle.properties to contain only essential Gradle JVM settings (2 lines)
• Added clear comments for better documentation

The build script now provides superior IDE support and type safety while maintaining a clean separation between Gradle settings and mod configuration.

gradle.propertiesを使わない方法に変更しました。すべての設定値をModConfigオブジェクトとして直接build.gradle.ktsに定義することで、IDEの補完機能が完全に利用できるようになります。

変更内容:

• gradle.propertiesへの依存を完全に削除
• ModConfigオブジェクトですべてのパラメータを定義 (14個の設定値を過不足なく列挙)
• const valによる型安全性とコンパイル時検証
• ModConfig.プロパティ名でIDE補完が効く

よくできました

@copilot
gradle.propertiesだけ整理しておいて
最初の2行以外はいらなくなったはず

@copilot

最初の2行以外はいらなくなったはず

gradle.propertiesを整理しました。最初の2行（JVM設定）のみを残し、ModConfigオブジェクトに移行済みのmod/environment設定を全て削除しました。

変更内容:

• 19行の不要なプロパティを削除
• Gradle JVM設定のみを保持
• ModConfigオブジェクトで全ての設定を管理
