Description Sylvain Gravel 2016-12-01 15:36:39 UTC
I'm trying to have a step in my build process to change my plist to allow opening random sites in debug (deactivating ATS)

So I added the following target in my iOS csproj to invoke PListBuddy :

 <Target Name="SetupPlist"
    <Exec Command="/usr/libexec/PlistBuddy -c 'Set :NSAppTransportSecurity:NSAllowsArbitraryLoads YES' '$(_AppBundlePath)Info.plist'"
    	    Condition="'$(BuildSessionId)' != '' And
    	               ('$(Platform)' == 'iPhoneSimulator' Or
    	    					  ('$(Configuration)' != 'AppStore' And '$(Configuration)' != 'Ad-Hoc'))">


The command seems to run fine but I get an error which prevents a successful build : 

2>  Executing: /usr/libexec/PlistBuddy -c 'Set :NSAppTransportSecurity:NSAllowsArbitraryLoads YES' 'bin/iPhone/Debug/AppliOrange.iOS.app/Info.plist'
2>D:\Programmation\Xamarin\AppliOrange\AppliOrange\AppliOrange.iOS\AppliOrange.iOS.csproj(449,5): error : JsonSerializationException: Error setting value to 'StdOutEncoding' on 'Microsoft.Build.Tasks.Exec'.
2>D:\Programmation\Xamarin\AppliOrange\AppliOrange\AppliOrange.iOS\AppliOrange.iOS.csproj(449,5): error : InvalidOperationException: Task attempted to log before it was initialized. Message was: "Exec" task received an invalid value for the "StdOutEncoding" parameter.
2>D:\Programmation\Xamarin\AppliOrange\AppliOrange\AppliOrange.iOS\AppliOrange.iOS.csproj(449,5): error : 
2>Build FAILED.


Any clue?

This looks like an issue with the Visual Studio side of things (serialization to send to the Mac side, perhaps?)
Comment 2 Sylvain Gravel 2016-12-02 15:28:15 UTC
Tried in Tamarin Studio and I get the following :

	Target SetupPlist:
		Executing: /usr/libexec/PlistBuddy -c 'Set :NSAppTransportSecurity:NSAllowsArbitraryLoads YES' 'bin/iPhoneSimulator/Debug/AppliOrange.iOS.app/Info.plist'
/Users/gulogulosoftware/Projects/AppliOrange/AppliOrange/AppliOrange.iOS/AppliOrange.iOS.csproj: error : Error executing task Exec: The parameter 'ConsoleOutput' was not found for the 'Exec' task.
		Build FAILED.
Comment 3 Jeffrey Stedfast 2016-12-02 17:04:15 UTC
Okay, then the problem is with xbuild and/or its Task implementations.

The iOS targets/tasks don't do anything with the Exec task.

Sylvain, could you please share the project file - `AppliOrange/AppliOrange/AppliOrange.iOS/AppliOrange.iOS.csproj` ? I want to see the exact target definition that you have there.
Comment 5 Ankit Jain 2016-12-02 17:21:10 UTC
Also, could you please attach the full diagnostic build log, using https://developer.xamarin.com/guides/android/troubleshooting/troubleshooting/#Diagnostic_MSBuild_Output ?
