什么是MSDeploy NullReferenceException?

当我从构建脚本运行MSDeploy时,我得到了这个NullReferenceException。有趣的是,该项目部署。这让我发疯了。注意:这是一个网站项目,而不是Web应用程序项目。

我在构建目标文件中使用它:

    <ItemGroup>     
        <DeploySource Include="DirPath">
            <Path>C:\TFS\MySiteBranch\PrecompiledWeb\Source</Path>
            <ComputerName>myComputer</ComputerName>
            <UserName>anAdminAccount</UserName>
            <Password>itsPassword</Password>
        </DeploySource>
    </ItemGroup>

    <ItemGroup>
        <TestDeployDest Include="DirPath">
            <Path>C:\TFS_Build\POC\Test</Path>
            <ComputerName>myComputer</ComputerName>
            <UserName>anAdminAccount</UserName>
            <Password>itsPassword</Password>
        </TestDeployDest>
    </ItemGroup>    

    <Target name="Deploy">

        <PropertyGroup>
            <WhatIf Condition="'$(WhatIf)'==''">false</WhatIf>
            <MSDeployPath Condition="'$(MSDeployPath)'==''">C:\Program Files\IIS\Microsoft Web Deploy V2</MSDeployPath>
        </PropertyGroup>

        <MSDeploy Condition="'@(TestDeployDest)'!=''"
            Whatif="$(WhatIf)"
            Verb="sync"
            Source="@(DeploySource)"
            Destination="@(TestDeployDest)"
            ExePath="$(MSDeployPath)"
        />
</target>

这是错误:

"C:\TFS\MySiteBranch\Source\source.csproj" (Deploy target) (1) ->
(Deploy target) ->

我可以尝试一些想法吗?

尝试在MSDeploy Elements上使用 ContinueOnError =“true”作为以下代码:

<ItemGroup>     
        <DeploySource Include="DirPath">
            <Path>C:\TFS\MySiteBranch\PrecompiledWeb\Source</Path>
            <ComputerName>myComputer</ComputerName>
            <UserName>anAdminAccount</UserName>
            <Password>itsPassword</Password>
        </DeploySource>
    </ItemGroup>

    <ItemGroup>
        <TestDeployDest Include="DirPath">
            <Path>C:\TFS_Build\POC\Test</Path>
            <ComputerName>myComputer</ComputerName>
            <UserName>anAdminAccount</UserName>
            <Password>itsPassword</Password>
        </TestDeployDest>
    </ItemGroup>    

    <Target name="Deploy">

        <PropertyGroup>
            <WhatIf Condition="'$(WhatIf)'==''">false</WhatIf>
            <MSDeployPath Condition="'$(MSDeployPath)'==''">C:\Program Files\IIS\Microsoft Web Deploy V2</MSDeployPath>
        </PropertyGroup>

        <MSDeploy ContinueOnError="true" Condition="'@(TestDeployDest)'!=''"
            Whatif="$(WhatIf)"
            Verb="sync"
            Source="@(DeploySource)"
            Destination="@(TestDeployDest)"
            ExePath="$(MSDeployPath)"
        />
</target>

我有同样的问题;并且只能使用此处描述的修复程序来解决它: http://forums.iis.net/p/1187159/2016131.aspx#2016131

对我来说,使用VSMSDeploy任务不是一个选项,因为我们运行x64服务器和Web应用程序。 Visual Studio仅运行x86版本的msbuild和msdeploy,因此VSMSDeploy仅适用于x86服务器和站点。我正在使用appHostConfig提供程序来存储IIS配置,而appHostConfig无法将x64站点同步到msdeploy的x86实例。

我刚刚碰到了同样的事情。我无法弄清问题是什么,但我能够通过使用VSMSDeploy而不是MSDeploy来解决它。这两个任务都在同一个DLL中,并且在Microsoft.Web.Publishing.targets中有使用它的示例。

我能够使用Web Deploy Project进行部署。
