Deploys your build to Steam via SteamCMD. Handles VDF manifest generation, SteamGuard authentication, and upload.

stages {
    perforce.sync()
    ue5.build()
    steam.deploy()
    discord.alert()
}

• SteamCMD installed on the build agent
• A Steam developer account with app/depot access
• Steam credential in Jenkins (username/password)

1. Navigate to your team's folder in Jenkins
2. Credentials > Add Credentials
3. Kind: Username with password
4. Username: your Steam username
5. Password: your Steam password
6. ID: e.g., steam-myproject

1. Generates a depot VDF manifest from the template in resources/
2. Generates an app VDF manifest with build metadata
3. Attempts deploy without SteamGuard
4. If SteamGuard is required, prompts for the code in Jenkins (3-minute timeout)
5. Uploads the build to the specified depot and optionally sets a branch live

If your Steam account has SteamGuard enabled (it should), the first deploy will fail and Jenkins will prompt you to enter a SteamGuard code. Check your email or authenticator app, enter the code in the Jenkins input prompt within 3 minutes.

Tip: After the first successful SteamGuard authentication, SteamCMD caches the token on the agent. Subsequent deploys from the same agent won't need the code again (until the token expires).
