"Illegal characters in path" error when building UWP project with SQLite extension on VSTS Hosted agent

Question

When using a Hosted agent to build my UWP application on VSTS I'm getting an error:

_GenerateAppxSymbolPackage:
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\AppxPackage\PDBCopy.exe C:\a\1\s\App\MyApp\bin\ARM\Debug\MyApp.pdb obj\ARM\Debug\Stripped\MyApp.pdb 
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\AppxPackage\PDBCopy.exe C:\a\1\s\App\Extensions\UAP\v0.8.0.0\ExtensionSDKs\SQLite.UWP.2015\3.11.1\Redist\Debug\ARM\sqlite3.pdb obj\ARM\Debug\Stripped\sqlite3.pdb 
##[error]C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\AppxPackage\Microsoft.AppXPackage.Targets(2550,5): Error APPX0002: Task 'GenerateAppxSymbolPackage' failed. Illegal characters in path.

My build definition runs for app solution file against VS15 with params:

/p:AppxBundlePlatforms="$(BuildPlatform)" /p:AppxPackageDir="$(Build.BinariesDirectory)\AppxPackages\" /p:AppxBundle=Always /p:UapAppxPackageBuildMode=CI

Everything else is default UWP build definition configuration on VSTS.

Note: my CI build for the same project builds successfully. The only difference there is the lack of /p:UapAppxPackageBuildMode=CI flag.

Any ideas / hints on what might be wrong with those paths? Or is it some bug in VSTS?

Answer 1

The MSBuild Arguments should be like:

/p:AppxBundlePlatforms="$(BuildPlatform)" /p:AppxPackageDir="$(Build.BinariesDirectory)\AppxPackages\\" /p:AppxBundle=Always

There is a \\ after AppxPackages, not \ .

Deleting everything except .git folder and then doing hard reset helped.
