uloop-compile

name	uloop-compile
description	Compile the Unity project and report errors/warnings. Use after C# edits or when a full Domain Reload compile is needed.

uloop compile

Execute Unity project compilation.

Usage

uloop compile [--force-recompile <true|false>] [--wait-for-domain-reload <true|false>]

Parameters

Parameter	Type	Default	Description
--force-recompile	boolean value	false	Force full recompilation (triggers Domain Reload). Rarely needed — see "When to use --force-recompile" below. Pass true or false; bare flags are not accepted.
--wait-for-domain-reload	boolean value	false	Wait until Domain Reload completes before returning. Pass true or false; bare flags are not accepted.

When to use --force-recompile

Almost never. Unity itself detects changed files — even when they were edited outside the Editor, a plain uloop compile runs every recompilation the changes require. A forced full recompile can freeze the Editor for a long time on large projects, and with --wait-for-domain-reload true the response crosses a Domain Reload so Success comes back as null, making it useless as a verification step. The only legitimate use: surfacing warnings hidden by other asmdefs with a full build.

Global Options

Option	Description
--project-path <path>	Optional. Use only when the target Unity project is not the current directory.

Examples

# Check compilation
uloop compile

# Force full recompilation
uloop compile --force-recompile true

# Force recompilation and wait for Domain Reload completion
uloop compile --force-recompile true --wait-for-domain-reload true

# Wait for Domain Reload completion even without force recompilation
uloop compile --force-recompile false --wait-for-domain-reload true

Output

Returns JSON:

• Success: boolean
• ErrorCount: number
• WarningCount: number

Troubleshooting

Diagnose the failure mode before retrying.

Stale lock files (CLI hangs or shows "Unity is busy" while Unity Editor is running):

uloop fix

This removes any leftover lock files (compiling.lock, domainreload.lock, serverstarting.lock) from the Unity project's Temp directory. Then retry uloop compile.

Unity Editor not running (CLI returns a connection failure and no Unity process is alive):

uloop launch

uloop launch auto-detects the project at the current working directory and opens it in the matching Unity Editor version. After Unity finishes launching, retry uloop compile.
