Do not set /m parameter for MSBuild by default

What You Are Seeing?

Xamarin based projects are not compiling correctly. Either SDK files are not found or Android packages are not downloading correctly on a clean build server with minimal build tools installed.

Note: This works perfectly if I execute msbuild manually on exact same system

and

I have also replicated this on both a Windows 10 (Build 1511 base) and a Windows 2016 Tap 5 build server.

It seems that there is something that cake is doing when it executes msbuild that is resulting in the error.

What is Expected?

Build should work as expected. if I run msbuild manually it works 100% of the time on a clean system

What version of Cake are you using?

Tried

• Version 0.13.0+Branch.main.Sha.f7346f2a5fb4e19a24cf15780ce635529f921be4

• Are you running on a 32 or 64 bit system?

  64

What environment are you running on? Windows? Linux? Mac?

• Windows 2012R2
• Windows 10 (based on 1511)
• Windows 2015 Tap 5

Are you running on a CI Server? If so, which one?

• Standalone and appveyor (both have same issue)

https://ci.appveyor.com/project/xlabs/xamarin-forms-labs-hva8p/build/2.3.0.3.master

How Did You Get This To Happen? (Steps to Reproduce)

Test 1 Windows 2012 R2

• Setup
  • Windows Updates as of 7/21/2016
  • Install Chocolatey
  • Install 7zip
  • Install Visual Studio 2015 Enterprise w/Update 3 (full install all components except emulators and lightspeed)
• Build Process
  • Clone repository
  • Execute .\build.ps1 -Target Package
  • Result Fails
  • Immediately execute .\build.ps1 -Target Package (which does a full clean)
  • Result Succeeds

Test 2 Windows 2012 R2

• Setup
  • Windows Updates as of 7/21/2016
  • Install Chocolatey
  • Install 7zip
  • Install Visual Studio 2015 Enterprise w/Update 3 (full install all components except emulators and lightspeed)
  • Install Xamarin Tools (from Xamarin.com) with defaults (see screenshots below)
• Build Process
  • Clone repository
  • Execute .\build.ps1 -Target Package
  • Result Fails

Test 3 Windows 2012 R2

• Setup
  • Windows Updates as of 7/21/2016
  • Install Chocolatey
  • Install 7zip

  • Install Xamarin Tools (from Xamarin.com) with defaults (see screenshots below)
• Build Process
  • Clone repository
  • Execute …nuget\nuget restore .\src\XLabs.sln -ConfigFile …nuget\nuget.config
  • Execute msbuild /m /v:normal /p:Configuration=“Release” /p:Platform=“Any CPU” /p:TreatWarningsAsErrors=False /target:Build "E:/Builds/GitHub/Xamarin-Forms-Labs/src/XLabs.sln
  • Result Fails

Test 4 Windows 2012 R2

• Setup
  • Windows Updates as of 7/21/2016
  • Install Chocolatey
  • Install 7zip
  • Install Visual Studio 2015 Enterprise w/Update 3 (full install all components except emulators and lightspeed)
  • Install Xamarin Tools (from Xamarin.com) with defaults (see screenshots below)
• Build Process
  • Clone repository
  • Execute …nuget\nuget restore .\src\XLabs.sln -ConfigFile …nuget\nuget.config
  • Execute msbuild /v:normal /p:Configuration=“Release” /p:Platform=“Any CPU” /p:TreatWarningsAsErrors=False /target:Build "E:/Builds/GitHub/Xamarin-Forms-Labs/src/XLabs.sln
  • Result Sucess

The issue seems to be related to the /m property

@gep13 not sure yet – still testing. That will be one of the tests I run and I’ll let you know what the result it.

Using the following

MSBuild(solution, settings =>
    settings.SetPlatformTarget(PlatformTarget.MSIL)
                .SetMaxCpuCount(1)
                .WithProperty("TreatWarningsAsErrors",buildSettings.Build.TreatWarningsAsErrors.ToString())
                .WithTarget("Build")
                .SetConfiguration(configuration));

Seems to work – everything compiles now.

I have also submitted an issue on the msbuild git repository
