Custom Build Scripts

As described in the Build Services Reference, MyGet Build Services supports scripting your own build using a batch file named build.bat, build.cmd or using a PowerShell script. This page lists several example build.bat files which can be used in other projects as well.

Note: All environment variables described in the Build Services Reference can be used in build.bat files.

Simple build.bat

The following build.bat executes several steps:

• Compile the solution using msbuild
• Create NuGet packages for specific projects in the solution, also creating symbols packages. Package version will come from %PackageVersion% environment variable, if set.

build.bat:

@echo Off
set config=%1
if "%config%" == "" (
   set config=Release
)

set version=
if not "%PackageVersion%" == "" (
   set version=-Version %PackageVersion%
)

REM Build
"%programfiles(x86)%\MSBuild\14.0\Bin\MSBuild.exe" YourSolution.sln /p:Configuration="%config%" /m /v:M /fl /flp:LogFile=msbuild.log;Verbosity=Normal /nr:false

REM Package
mkdir Build
call %nuget% pack "YourSolution\ProjectA.csproj" -symbols -o Build -p Configuration=%config% %version%
call %nuget% pack "YourSolution\ProjectB.csproj" -symbols -o Build -p Configuration=%config% %version%

build.bat creating a single NuGet package containing all projects

The following build.bat executes several steps:

• Compile the solution using msbuild
• Create a single NuGet package containing all referenced projects. Package version will come from %PackageVersion% environment variable, if set.

build.bat:

@echo Off
set config=%1
if "%config%" == "" (
   set config=Release
)

set version=
if not "%PackageVersion%" == "" (
   set version=-Version %PackageVersion%
)

REM Build
"%programfiles(x86)%\MSBuild\14.0\Bin\MSBuild.exe" YourSolution.sln /p:Configuration="%config%" /m /v:M /fl /flp:LogFile=msbuild.log;Verbosity=Normal /nr:false

REM Package
mkdir Build
call %nuget% pack "YourSolution\ProjectA.csproj" -IncludeReferencedProjects -o Build -p Configuration=%config% %version%

build.bat manually running unit tests using default test runner

The following build.bat executes several steps:

• Compile the solution using msbuild
• Run unit tests using default MyGet test runner (Gallio Echo)
• Create a single NuGet package containing all referenced projects, also creating symbols packages. Package version will come from %PackageVersion% environment variable, if set.

This build.bat also verifies error level after every step and reports build success/failure back to MyGet.

build.bat:

@echo Off
set config=%1
if "%config%" == "" (
   set config=Release
)

set version=
if not "%PackageVersion%" == "" (
   set version=-Version %PackageVersion%
)

REM Build
"%programfiles(x86)%\MSBuild\14.0\Bin\MSBuild.exe" YourSolution.sln /p:Configuration="%config%" /m /v:M /fl /flp:LogFile=msbuild.log;Verbosity=Normal /nr:false
if not "%errorlevel%"=="0" goto failure

REM Unit tests
%GallioEcho% YourSolution\ProjectA.Tests\bin\%config%\ProjectA.Tests.dll
if not "%errorlevel%"=="0" goto failure

REM Package
mkdir Build
call %nuget% pack "YourSolution\YourSolution.ProjectA.csproj" -symbols -o Build -p Configuration=%config% %version%
if not "%errorlevel%"=="0" goto failure

:success
exit 0

:failure
exit -1

build.bat manually running unit tests using custom test runner

The following build.bat executes several steps:

• Compile the solution using msbuild
• Run unit tests using a custom test runner provided through the project's source control repository
• Create a single NuGet package containing a specific projects, also creating symbols packages. Package version will come from %PackageVersion% environment variable, if set.

This build.bat also verifies error level after every step and reports build success/failure back to MyGet.

build.bat:

@echo Off
set config=%1
if "%config%" == "" (
   set config=Release
)

set version=
if not "%PackageVersion%" == "" (
   set version=-Version %PackageVersion%
)

set nunit="tools\nunit\nunit-console.exe"

REM Build
"%programfiles(x86)%\MSBuild\14.0\Bin\MSBuild.exe" YourSolution.sln /p:Configuration="%config%" /m /v:M /fl /flp:LogFile=msbuild.log;Verbosity=Normal /nr:false
if not "%errorlevel%"=="0" goto failure

REM Unit tests
%nunit% YourSolution\ProjectA.Tests\bin\%config%\ProjectA.Tests.dll
if not "%errorlevel%"=="0" goto failure

REM Package
mkdir Build
call %nuget% pack "YourSolution\YourSolution.ProjectA.csproj" -symbols -o Build -p Configuration=%config% %version%
if not "%errorlevel%"=="0" goto failure

:success
exit 0

:failure
exit -1

build.bat manually running unit tests using custom test runner which is downloaded on the fly

The following build.bat executes several steps:

• Compile the solution using msbuild
• Download NUnit 2.6.4 from NuGet.org
• Run unit tests using the downloaded NUnit 2.6.4 test runner
• Create a single NuGet package containing a specific projects, also creating symbols packages. Package version will come from %PackageVersion% environment variable, if set.

This build.bat also verifies error level after every step and reports build success/failure back to MyGet.

build.bat:

@echo Off
set config=%1
if "%config%" == "" (
   set config=Release
)

set version=
if not "%PackageVersion%" == "" (
   set version=-Version %PackageVersion%
)

REM Build
"%programfiles(x86)%\MSBuild\14.0\Bin\MSBuild.exe" YourSolution.sln /p:Configuration="%config%" /m /v:M /fl /flp:LogFile=msbuild.log;Verbosity=Normal /nr:false
if not "%errorlevel%"=="0" goto failure

REM Unit tests
call %nuget% install NUnit.Runners -Version 2.6.4 -OutputDirectory packages
packages\NUnit.Runners.2.6.4\tools\nunit-console.exe /config:%config% /framework:net-4.5 YourSolution\ProjectA.Tests\bin\%config%\ProjectA.Tests.dll
if not "%errorlevel%"=="0" goto failure

REM Package
mkdir Build
call %nuget% pack "YourSolution\YourSolution.ProjectA.csproj" -symbols -o Build -p Configuration=%config% %version%
if not "%errorlevel%"=="0" goto failure

:success
exit 0

:failure
exit -1

build.bat doing manual package restore before build

The following build.bat executes several steps:

• Perform manual package restore for several projects' packages.config.
• Compile the solution using msbuild
• Create NuGet packages for specific projects in the solution, also creating symbols packages. Package version will come from %PackageVersion% environment variable, if set.

Note that the nuget.exe used is provided by the project itself through its source control, hence the calls to .nuget\nuget.exe.

build.bat:

@echo Off
set config=%1
if "%config%" == "" (
   set config=Release
)

set version=
if not "%PackageVersion%" == "" (
   set version=-Version %PackageVersion%
)

REM Package restore
call %NuGet% restore GoogleAnalyticsTracker\packages.config -OutputDirectory %cd%\packages -NonInteractive
call %NuGet% restore GoogleAnalyticsTracker.WP7\packages.config -OutputDirectory %cd%\packages -NonInteractive

REM Build
"%programfiles(x86)%\MSBuild\14.0\Bin\MSBuild.exe" GoogleAnalyticsTracker.sln /p:Configuration="%config%" /m /v:M /fl /flp:LogFile=msbuild.log;Verbosity=Normal /nr:false

REM Package
mkdir Build
mkdir Build\net40
call %NuGet% pack "GoogleAnalyticsTracker\GoogleAnalyticsTracker.csproj" -symbols -o Build\net40 -p Configuration=%config% %version%
copy GoogleAnalyticsTracker\bin\%config%\*.dll Build\net40
copy GoogleAnalyticsTracker\bin\%config%\*.pdb Build\net40

PowerShell Build.ps1 example creating Chocolatey packages

The following is a Powershell script that, instead of creating NuGet packages, creates Chocolatey packages.

build.ps1:

Write-Host "Building Chocolatey packages..."

Write-Host "Finished building Chocolatey packages."

.NET Core running xunit tests

MyGet can build .NET Core projects out of the box. However, creating a build.bat often makes a lot of sense if you want to add a custom test runner or want to have more control over the build process. The following files make up a build for a .NET Core library that:

• Restores packages using dotnet restore
• Builds packages using dotnet build (or MSBuild 15.0)
• Runs tests using dotnet test
• Packages the library using dotnet pack

Make sure the library project itself either has a MyLibrary.nuspec which holds package metadata, or that the .csproj contains required metadata.

The following build uses the dotnet command to do all the work, except compilation. We'll be using msbuild for that as it automatically resolves project dependencies and builds projects in the right order.

We're also using MyGet's %BuildCounter% environment variable to generate a version number suffix (which will be appended to the version number). This is optional and can be removed if you prefer using the version numbers .NET Core generates itself.

build.bat:

@echo Off
set config=%1
if "%config%" == "" (
    set config=Release
)

set version=
if not "%BuildCounter%" == "" (
   set packversionsuffix=--version-suffix ci-%BuildCounter%
