SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill identifies when multiple MSBuild projects or build configurations write to the same output or intermediate output directories, which is a common cause of build failures and intermittent errors.

Core Features & Use Cases

Detects OutputPath and IntermediateOutputPath clashes: Pinpoints conflicts arising from multi-targeting, shared directories, or multiple solution builds.
Guides through binlog analysis: Provides a step-by-step process to load binlogs, list projects, and inspect evaluations and global properties.
Identifies common causes and fixes: Offers solutions for multi-targeting issues, shared output directories, and redundant project instances.

Quick Start

Use the check-bin-obj-clash skill to analyze the build log located at 'C:/path/to/build.binlog'.

FAQPage Schema

Why does my MSBuild fail with file access errors during multi-targeting?▼

MSBuild file access errors during multi-targeting often occur when multiple project configurations write to the same output or intermediate directories. Analyzing binary logs helps pinpoint these output path clashes and resolve the conflicts.

How do I find MSBuild output path conflicts using a binlog?▼

To find MSBuild output path conflicts using a binlog, load the binary log file, list the evaluated projects, and inspect their global properties. This process identifies overlapping OutputPath and IntermediateOutputPath values causing build failures.

What causes intermittent MSBuild build failures in shared output directories?▼

Intermittent MSBuild build failures in shared output directories are caused by redundant project instances writing to the exact same intermediate output paths. Binlog evaluation inspection reveals these clashes to guide targeted directory separation fixes.

Can I check for intermediate output path clashes across multiple solution builds?▼

Yes, you can check for intermediate output path clashes across multiple solution builds by analyzing the generated binary logs. The analysis detects shared directories and global property conflicts that cause file access errors.

What is the best way to troubleshoot MSBuild output path clashes?▼

The best way to troubleshoot MSBuild output path clashes is to analyze binary logs to inspect project evaluations and global properties. This identifies whether multi-targeting or shared directories are causing the build failures.
