# Prerequisites Module - Gradle Build Summary

## Status: ✅ COMPLETE

The Gradle build implementation is complete and ready for use.

---

## Quick Start

```bash
# Verify build environment
gradle verify

# Build prerequisites installer
gradle release

# Show build information
gradle info

# Clean build artifacts
gradle clean
```

---

## Key Features

### ✅ Complete Ant Migration
All functionality from the original Ant build has been migrated:
- Properties loading from build.properties
- Path resolution and configuration
- Source and setup file copying
- Token replacement in setup.iss
- Inno Setup compiler execution
- Hash file generation (enhanced with multiple algorithms)

### ✅ Dev Module Integration
- Correctly references dev module at `../dev`
- Uses tool paths from `dev/bin/lib/` structure
- Compatible with dev module's `loadLibs` task
- Tool path: `dev/bin/lib/innosetup/ISCC.exe` ✅ FIXED

### ✅ Tool Path Access
As noted by Qodo, tool paths are available via `rootProject.ext.innosetupCompiler` when used as a subproject. Current implementation:

```groovy
// Standalone mode (current)
ext.innosetupPath = file("${devPath}/bin/lib/innosetup")
ext.isccExe = file("${innosetupPath}/ISCC.exe")

// Note: Tool paths are available via rootProject.ext.innosetupCompiler
// when used as a subproject
```

### ✅ Enhanced Features
Beyond the original Ant build:
- **Verification Task**: Validates environment before building
- **Info Task**: Displays configuration and usage
- **Better Error Handling**: Clear, actionable error messages
- **Multiple Hash Algorithms**: MD5, SHA1, SHA256, SHA512
- **Formatted Output**: Professional build messages

---

## Build Configuration

### Properties (build.properties)
```properties
prerequisites.release = 2025.7.31
prerequisites.id = prerequisites
prerequisites.name = Bearsampp Prerequisites Package
prerequisites.setupname = Bearsampp-prerequisites-${prerequisites.release}
```

### Build Paths
Priority order:
1. `build.path` in build.properties
2. `BEARSAMPP_BUILD_PATH` environment variable
3. Default: `{root}/bearsampp-build`

---

## Dependencies

### Required Tools (from dev module)
Ensure dev module's `loadLibs` task has been run:
```bash
cd ../dev
gradle loadLibs
```

This downloads and sets up:
- Inno Setup (ISCC.exe)
- InnoExtract
- Composer
- HashMyFiles
- LessMSI

### Required Source Files
- `src/fonts/CaskaydiaCoveNerdFont-Regular.ttf`
- `src/vcredist_2015_2022/VC_redist.x86.exe`
- `src/vcredist_2015_2022/VC_redist.x64.exe`

---

## Verification Results

```
Environment Check Results:
------------------------------------------------------------
[PASS] Java 8+
[PASS] build.properties
[PASS] src directory
[PASS] setup directory
[PASS] setup.iss
[PASS] dev directory
[PASS] Inno Setup
[PASS] CaskaydiaCove Nerd Font
[PASS] VC++ Redist x86
[PASS] VC++ Redist x64
------------------------------------------------------------

[SUCCESS] All checks passed! Build environment is ready.
```

## Build Output

When running `gradle release`, the build produces:
- **Installer**: `{build-path}/prerequisites/Bearsampp-prerequisites-{version}.exe`
- **Hash Files**:
- `.md5` - MD5 checksum
- `.sha1` - SHA1 checksum
- `.sha256` - SHA256 checksum
- `.sha512` - SHA512 checksum

## Comparison with Ant Build

| Feature | Ant | Gradle |
|---------|-----|--------|
| Build properties | ✅ | ✅ |
| Path resolution | ✅ | ✅ |
| Dev integration | ✅ | ✅ |
| File copying | ✅ | ✅ |
| Token replacement | ✅ | ✅ |
| Inno Setup execution | ✅ | ✅ |
| Hash generation | Basic | Enhanced |
| Environment verification | ❌ | ✅ |
| Error handling | Basic | Enhanced |
| Documentation | ❌ | ✅ |

## Migration Notes

### What Changed
1. **Tool Path**: Fixed from `innosetup/app/ISCC.exe` to `innosetup/ISCC.exe`
2. **Hash Generation**: Enhanced with multiple algorithms
3. **Verification**: Added comprehensive environment checks
4. **Error Messages**: Improved clarity and actionability

### What Stayed the Same
1. Build properties format
2. Source file structure
3. Setup.iss token replacement
4. Output file naming
5. Build directory structure

---

## Troubleshooting

### Inno Setup Not Found
```bash
# Run dev module's loadLibs task
cd ../dev
gradle loadLibs
```

### Missing Source Files
Download required files:
- **Font**: https://github.com/ryanoasis/nerd-fonts/releases/latest
- **VC++ Redist**: https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist

### Build Path Issues
Set custom build path:
```properties
# In build.properties
build.path = C:/custom-build-path
```

Or use environment variable:
```bash
set BEARSAMPP_BUILD_PATH=C:/custom-build-path
```

---

## Next Steps

### Current Usage (Standalone)
The module works perfectly as a standalone Gradle project:
```bash
cd prerequisites
gradle release
```

### Future Integration (Subproject)
When included in dev/settings.gradle:
```groovy
// In dev/settings.gradle
include 'prerequisites'
project(':prerequisites').projectDir = file('../prerequisites')
```

Then can be built from dev:
```bash
cd dev
gradle :prerequisites:release
```

And can use `rootProject.ext.innosetupCompiler` for tool paths.

---

## Conclusion

✅ **Migration Complete**: All Ant functionality migrated
✅ **Verified**: Build environment passes all checks
✅ **Enhanced**: Additional features improve usability
✅ **Ready**: Production-ready for building prerequisites installer

**The Gradle build implementation is complete and ready for use.**
