File contents

npx --yes uloop-cli@2.2.0 compile

Execute Unity project compilation.

Usage

npx --yes uloop-cli@2.2.0 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 npx --yes uloop-cli@2.2.0 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
npx --yes uloop-cli@2.2.0 compile

# Force full recompilation
npx --yes uloop-cli@2.2.0 compile --force-recompile true

# Force recompilation and wait for Domain Reload completion
npx --yes uloop-cli@2.2.0 compile --force-recompile true --wait-for-domain-reload true

# Wait for Domain Reload completion even without force recompilation
npx --yes uloop-cli@2.2.0 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):

npx --yes uloop-cli@2.2.0 fix

This removes any leftover lock files (compiling.lock, domainreload.lock, serverstarting.lock) from the Unity project's Temp directory. Then retry npx --yes uloop-cli@2.2.0 compile.

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

npx --yes uloop-cli@2.2.0 launch

npx --yes uloop-cli@2.2.0 launch auto-detects the project at the current working directory and opens it in the matching Unity Editor version. After Unity finishes launching, retry npx --yes uloop-cli@2.2.0 compile.
