---

name: keil-build description: Compile Keil MDK projects (.uvprojx) via command line using Keil UV4 compiler, supporting incremental build and full rebuild, and parse build results. Trigger scenarios: (1) Compile Keil/MDK ARM project, (2) User mentions "build", "compile", "construct" project, (3) Need to check if project has build errors or warnings, (4) Need to compile before flashing firmware. Even if user just says "compile it for me" or "build this project", this skill should be used.

Keil Project Compilation

Invoke py_keil_build.py to compile projects via Keil UV4 command-line interface, and return structured build results.

Tool Script

Script Path: py_keil_build.py Dependencies: Python 3.x standard library + Installed Keil MDK (with UV4.exe)

Usage

# Incremental build (default)
python py_keil_build.py -p <project.uvprojx>

# Full rebuild (clean rebuild)
python py_keil_build.py -p <project.uvprojx> -r

# Specify UV4.exe path
python py_keil_build.py -p <project.uvprojx> -k "D:\keil\UV4\UV4.exe"

Parameter Description

Parameter	Short	Description	Default
--project	-p	.uvprojx file path	Required
--keil	-k	UV4.exe path	D:\application\keil_v5\UV4\UV4.exe
--rebuild	-r	Full rebuild	Incremental build

Output Structure

Returns JSON format result:

{
  "status": "success",       // "success" or "failed" or "error"
  "log_path": "C:\\project\\Objects\\GD32F303RCT6.build_log.htm",  // 编译日志路径
  "errors": 0,                // 编译错误数
  "warnings": 3               // 编译警告数
}

Notes

• Keil default installation path: D:\application\keil_v5\UV4\UV4.exe, if different please specify with -k
• Build output is printed directly to terminal (no log file generated)
• Build success is determined by checking if *build_log*.htm exists after compilation
  • First checks: <project_dir>\Objects\*build_log*.htm
  • Falls back to searching recursively in project directory

Typical Workflow

1. First use keil-parser to confirm project configuration is correct
2. Call this tool to build, check if errors_count is 0
3. After successful build, use jlink-download to flash firmware
