Issue Description

We are running this task in a release pipeline in Azure DevOps. Last successful run was yesterday on version 4.214.0. It looks like this task just recently started failing, with version 4.216.2. Error message: Unrecognized argument 'Files\IIS\Microsoft'. All arguments must begin with "-".

The argument in question is the command itself: "C:\Program Files\IIS\Microsoft Web Deploy V3\msdeploy.exe"; it looks like it's not honoring the quotations and is parsing this string as individual arguments, hence the callout of "Files\IIS\Microsoft"

Same error with ISWebAppDeploymentOnMachineGroup here

[vmapetr]

@noellelc Thank you for reporting this issue. We are investigating it now.

[rfulgencio3]

Same problem

[felipefialho]

Is there any provision for normalization? It is impacting all deploys

[rodrigofudissaku]

Is there any workaround to this issue?

[tassioFront]

workaround: change App Deploy App Service task version. I've changed it to version 3 instead of 4.

[ericklodion]

Same here

[jopnine]

Where do i change App Deploy App Service version ? I mean.. the path.

• Edit pipeline
• Click on "Azure app service"
• Change the first combo option from 4. to 3.

I think this can help you: Go to Releases > select the project > Edit > under the envinronment click in 'jobs, taks' > click in Deploy Azure App Service > in 'Task version' select 3.*

NOTE: I try this but this not made effect for my deploy

Really ? for me it works fine ...

[jopnine]

I see, in my case i made small confusion. Im using "IIS web app deploy" instead of "Azure App Service"

[nicolasmohamed]

downgrade from Azure App Service Deploy 4. to 3. seems to work

[Rafael-Cassiano]

Same problem, even returning to 3.* is not working

• task: AzureRmWebAppDeployment@3

Some help ?

[marcopaivaa]

downgrade from Azure App Service Deploy 4. to 3. seems to work

is there any way to downgrade to a minor version (like 4.215.2) instead of changing from 4 to 3 with yaml?

[rafjsouza]

Any solutions for IISWebAppDeploymentOnMachineGroup task? Our pipeline is not working because of that error

[felipeagrela]

Same here in IISWebAppDeploymentOnMachineGroup...

[gabriel-alves-ivoryit]

Same here! Currently unable to release new versions of my applications.

I see that past executions of my release pipeline were using version 0.215.0 of the "IIS web app deploy" task. The failing one mentions version 0.216.0. That is what i see in the execution logs In the portal, though, the only task version option available is 0.*. It is obviously unchanged.

The error is the exact one as other people's around here:

##[error]Error: Unrecognized argument 'Files\IIS\Microsoft'. All arguments must begin with "-".

[Rafael-Cassiano]

Working with version 4. After leaving BUILD Image: windows-2019 and DEPLOY Image: windows-2022

[danton721]

Quick workaround was to rollback task to version 0.215.0.

In a self-hosted agent I did the following steps:

Inside agent directory: ./_work/_tasks/IISWebAppDeploymentOnMachineGroup[...]

1. Make sure that you have this directory: "0.215.0" (older versions might also work)
2. Delete content of directory "0.216.0" (I would recommend backing up)
3. Copy the contents of directory "0.215.0" inside "0.216.0"

This temporary solution did work for me with "IIS web app deploy" with a self-hosted agent

[felipeagrela]

Same here in IISWebAppDeploymentOnMachineGroup...

It comes work again... Seems that the problem version is not available anymore...

Problem Version: 0.216.0 Working Version: 0.215.0

[vmapetr]

We have reverted the affected tasks to previous versions in ADO, while we working on hotfixes:

• AzureRmWebAppDeployment - 4.216.2 -> 4.214.0
• IISWebAppDeploymentOnMachineGroup -0.216.0 -> 0.215.0

Sorry for the inconvenience.

Working fine now, thanks @vmapetr

How can i force to use 0.215.0 ?

My Azure Agent continue downloading the 0.216.0 version
