Psake, Powershell & Wix

Question

I have the below function as a part of my psake build. When the build is executing Candle.exe throws this error:

candle.exe : warning CNDL1098: 'ext .\Build\Packages\WixWeb\bin\WixIIsExtension.dll' is not a valid command line argument.

I think this is a problem with the way I am passing command line args but I cannot for the life of me figure it out.

Any powershell monkeys have suggestions?

function buildMsi($build_dir, $template, $directory) { 
    "Building Msi" 
    "Build Folder: $build_dir"
    "Wix Template: $template"
    "Website: $directory"

    $wixXml = [xml](Get-Content $template)
    $namespaceManager = New-Object Xml.XmlNamespaceManager($wixXml.PSBase.NameTable)
    $namespaceManager.AddNamespace("wi", "http://schemas.microsoft.com/wix/2006/wi")
    $components = $wixXml.Wix.Fragment.ComponentGroup

    WalkDirectory $wixXml.PSBase.SelectSingleNode("/wi:Wix/wi:Fragment/wi:DirectoryRef", $namespaceManager) $directory
    $wixXml.Save("$build_dir\WebContent.wxs")

    .\Build\WixWeb\bin\Candle.exe """-dProductName=Foo""`
         ""-dVersion=1.0.0.0""`

Answer 1

Try replacing your inner double quotes with single quotes, like so:

.\Build\WixWeb\bin\Candle.exe " ""-dProductName=Foo"" `
     ""-dVersion=1.0.0.0"" `
     ""-dProductID=0cd64670-5769-4e34-8b21-c6242e7ca5a2"" `
     ""-dUpgradeCode=307601e9-4eea-4b5c-938a-354115d5c419"" `
     ""-dAppPool=FooAppPool"" `
     ""-dInstallDirectory=Foo"" `
     ""-dWebAppDirectoryComponentId=CF57E626-1E95-4a89-A0E9-C1AD03C51B12"" `
     ""-dIIsAppPoolComponentId=D9138380-19B3-4123-9E22-AB2994B1024B"" `
     ""-dIIsWithAppPoolSettingsComponentId=02ca3f08-a1e8-48a3-b4d7-6f5f67c61b96"" `
     ""-dIIsWithoutAppPoolSettingsComponentId=d97791b0-f597-46c6-b159-541817527453"" `
     ""-ext '.\Build\WixWeb\bin\WixIIsExtension.dll'"" `
     ""-ext '.\Build\WixWeb\bin\WixUIExtension.dll'"" `
     "".\Build\WixWeb\Shell.wxs"" `
     "".\Build\stage\WebContent.wxs"" "

Futhermore, you might find it easier if you escape your double quotes correctly using `" (backtick followed by doublequote); the script might be more robust, too. The code sample would then become:

.\Build\WixWeb\bin\Candle.exe " `"-dProductName=Foo`" `
 `"-dVersion=1.0.0.0`" `
 `"-dProductID=0cd64670-5769-4e34-8b21-c6242e7ca5a2`" `
 `"-dUpgradeCode=307601e9-4eea-4b5c-938a-354115d5c419`" `
 `"-dAppPool=FooAppPool`" `
 `"-dInstallDirectory=Foo`" `
 `"-dWebAppDirectoryComponentId=CF57E626-1E95-4a89-A0E9-C1AD03C51B12`" `
 `"-dIIsAppPoolComponentId=D9138380-19B3-4123-9E22-AB2994B1024B`" `
 `"-dIIsWithAppPoolSettingsComponentId=02ca3f08-a1e8-48a3-b4d7-6f5f67c61b96`" `
 `"-dIIsWithoutAppPoolSettingsComponentId=d97791b0-f597-46c6-b159-541817527453`" `
 `"-ext '.\Build\WixWeb\bin\WixIIsExtension.dll'`" `
 `"-ext '.\Build\WixWeb\bin\WixUIExtension.dll'`" `
 `".\Build\WixWeb\Shell.wxs`" `
 `".\Build\stage\WebContent.wxs`" "

YMMV, though.
