Why do you want to do that? The Unreal Automation Tool (UAT) is designed to build, cook and package. You can see the UAT command-line that is called in the output log when you build/cook/package from the editor UI.

thank u.
I just want to build cook package from the webpage. Can I use UAT to do these thing from windows cmd ？not from editor UI. In that way, I can do these thing by calling local cmd from webpage . Do you have any better way to do these thing from webpage? thank you.

UAT and UBT are command line tools, you can invoke them without the editor, in fact the editor doesn’t do anything else special than invoking these tools with certain parameters depending on what you’ve set up through their UI.

Also, shameless promo here: I wrote a command line wrapper which makes it easier to operate Unreal tools for a project from the console. microdee/Nuke.Unreal: Automate Unreal tasks in style with Nuke and C# (github.com)

You execute UAT with:

UEROOT> Engine/Build/BatchFiles/RunUAT.bat <args>

The arguments are a little complicated. Best bet is to do the operation in the editor and then copy and paste the arguments from the output log to your script.

Here is a snippet from our internal build script for some reference:

        fury.shell.run(
            runuat,
            'BuildCookRun',
            '-nop4',
            '-utf8output',
            '-cook',
            f'-project={project}',
            f'-target={options.target}',
            unrealcmd,
            f'-platform={platform}',
            '-ddc=DerivedDataBackendGraph',
            '-stage',
            '-archive',
            '-package',
            '-build',
            '-compressed',
            '-iostore',
            '-pak',
            '-prereqs',
            f'-archivedirectory={str(fulltmpdirname)}',
            *extraopts,
            '-nodebuginfo',
        )
