.SYNOPSIS Compiles and builds the chocolatey package defined in the ChocolateyPackage .DESCRIPTION Using the given ChocolateyPackage object, performs the following: * Creates a NuSpec file using the package manifest section * Downloads all remote files defined in the package * Copies all local files defined in the package * Runs an optional process script for post-processing of package files * Builds the package using choco pack The path to the final package file is returned. Note that during the build process a temporary directory is created in the OutPath directory to hold files and appropriate write permissions are required. .PARAMETER Package The ChocolateyPackage to build .PARAMETER OutPath The output directory where the final package file will be placed .PARAMETER PreProcess An optional script block that is ran before the package process script. This script block receives the same parameters as the package process script. .PARAMETER ChocolateyPath The path to the choco binary - defaults to 'choco' .PARAMETER KeepFiles If set, does not delete the package files gathered during the build process. This is usually useful for debugging packages. .PARAMETER ScanFiles Whether or not to scan any downloaded files using Windows Defender .EXAMPLE Build-ChocolateyPackae ` -Package $myPackage ` -OutPath C:\path\to\package\output ` -ScanFiles .OUTPUTS The path to the final package file #> Function Build-ChocolateyPackage { [cmdletbinding()] param( [Parameter( Mandatory = $true, Position = 1, ValueFromPipeline = $true )] [ChocolateyPackage] $Package, [Parameter( Mandatory = $true, Position = 2 )] [string] $OutPath, [scriptblock] $PreProcess = {}, [string] $ChocolateyPath = 'choco', [switch] $ScanFiles, [switch] $KeepFiles ) $buildDir = Join-Path $OutPath ($Package.Name + '-build') Write-Verbose ('Creating build directory at {0}...' -f $buildDir) New-Item -ItemType Directory $buildDir | Out-Null $nuspecPath = (Join-Path $buildDir ($Package.Manifest.Metadata.Id + '.nuspec')) Write-Verbose ('Creating NuSpec file at {0}...' -f $nuspecPath) $xml = New-ChocolateyNuSpec $Package.Manifest $xml.Save($nuspecPath) if ($Package.RemoteFiles.Count -gt 0) { Write-Verbose 'Downloading remote files...' foreach ($remoteFile in $Package.RemoteFiles) { $remoteFile | Get-RemoteFile -OutPath $buildDir -Scan:$ScanFiles | Out-Null } } if ($Package.LocalFiles.Count -gt 0) { Write-Verbose 'Copying local files...' foreach ($localFile in $Package.LocalFiles) { $outFile = Join-Path $buildDir $localFile.ImportPath if (!(Test-Path (Split-Path $outFile))) { New-Item -ItemType Directory -Path (Split-Path $outFile) | Out-Null } Write-Verbose ('Copying {0} to {1}...' -f $localFile.LocalPath, $outFile) Copy-Item $localFile.LocalPath $outFile | Out-Null } } if ($Package.Installer.InstallerPath) { $installerFolder = Join-Path $buildDir $Package.Installer.ScriptPath if (!(Test-Path $installerFolder)) { New-Item -ItemType Directory $installerFolder | Out-Null } $installerFilePath = Join-Path $installerFolder 'ChocolateyInstall.ps1' $installerFileContents = Build-InstallerFile $Package Write-Verbose ('Writing installer file to {0}...' -f $installerFilePath) Set-Content $installerFilePath $installerFileContents | Out-Null } $PreProcess.Invoke($buildDir, $Package) if ($Package.processScript) { Write-Verbose ('Calling process script at {0}...' -f $Package.processScript) $proc = Get-Command $Package.processScript | Select-Object -ExpandProperty ScriptBlock $proc.Invoke($buildDir, $Package) | Out-Null } if (!$Package.Shim) { Write-Verbose "Preventing shimming of exe's..."
