cannot import google calendar api library to PowerShell - powershell

Question

I am trying to authenticate to google calendar using PowerShell. To do that, I have to install the "Google.Apis.Calendar.v3". And to do that I have to install the nuget package source. So I start with nuget.
PS C:\Windows\system32> register-PackageSource -Name MyNuGet -Location https://www.nuget.org/api/v2 -ProviderName NuGet
Name ProviderName IsTrusted Location
---- ------------ --------- --------
MyNuGet NuGet False https://www.nuget.org/api/v2
Then I install "Google.Apis.Calendar.v3" and get an error that there's a dependency loop.
PS C:\Windows\system32> Install-Package Google.Apis.Calendar.v3
Install-Package : Dependency loop detected for package 'Google.Apis.Calendar.v3'.
At line:1 char:1
+ Install-Package Google.Apis.Calendar.v3
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : Deadlock detected: (Google.Apis.Calendar.v3:String) [Install-Package], Exception
+ FullyQualifiedErrorId : DependencyLoopDetected,Microsoft.PowerShell.PackageManagement.Cmdlets.InstallPackage
So I add the -SkipDependencies option and the package gets installed.
PS C:\Windows\system32> Install-Package Google.Apis.Calendar.v3 -SkipDependencies
Name Version Source Summary
---- ------- ------ -------
Google.Apis.Calendar.v3 1.59.0.2759 MyNuGet Google APIs Client Library for working with Calendar v3....
I then try to authenticate with google calendar but get a message that the assembly is not loaded.
PS C:\Windows\system32> $credential = New-Object Google.Apis.Auth.OAuth2.ServiceAccountCredential
(
[Google.Apis.Auth.OAuth2.ServiceAccountCredential]::FromJsonFile("C:\Users\Windows\Desktop\calendar-346619-92e3766da662.json")
)
New-Object : Cannot find type [Google.Apis.Auth.OAuth2.ServiceAccountCredential]: verify that the assembly containing this

So I search for "google.apis.calendar.v3.dll" on my computer, find the .dll and try to load it but I get an error again.
PS C:\Windows\system32> Add-Type -Path "C:\Program Files\PackageManagement\NuGet\Packages\Google.Apis.Calendar.v3.1.59.0.2759\lib\net45\Google.Apis.Calendar.v3.dll"

I'm using Windows 10 and PowerShell version 5.1.19041.2364
How can I import this API library to PowerShell so I can authenticate to google calendar?

Answer 1

For starters, I got really angry that it was so difficult to install the packages, so this ought to fix that problem:
#requires -Modules #{ModuleName = 'PackageManagement'; ModuleVersion = '1.4.8.1'}
function Install-PackageRecursive
{
<#
.EXAMPLE
Install-PackageRecursive Google.Apis.Calendar.v3
#>
[CmdletBinding()]
param
(
[Parameter(Mandatory, ValueFromPipeline)]
[string]$Name,
[ValidateSet('CurrentUser', 'AllUsers')]
[string]$Scope = 'CurrentUser',
[SupportsWildcards()]
[string[]]$Exclude = ('NETStandard.Library', 'Microsoft.*', 'System.*'),
[switch]$Force,
[Parameter(DontShow)]
$Packages
)
begin
{
if (-not $Packages)
{
$Packages = #{}
$InstalledPackages = Get-Package
$InstalledPackages | ForEach-Object {
$Key = $_.CanonicalId -replace '#.*'
$Packages[$Key] = $_
}
$PSBoundParameters.Packages = $Packages
}
}
process
{
[void]$PSBoundParameters.Remove('Name')
$Name, $Version = $Name -replace '^nuget:' -split '/'
$Params = #{Name = $Name}
if ($Version)
{
$Params.RequiredVersion = $Version
}
if ($Exclude | Where-Object {$Name -like $_})
{
Write-Verbose "Excluded: $Name"
return
}
$Key = "nuget:$Name/$($Params.Version)"
$Package = $Packages[$Key]
if (-not $Package)
{
$Package = Get-Package #Params -ErrorAction Ignore
}
if (-not $Package)
{
$Package = Find-Package #Params
}
$Key = $Package.CanonicalId -replace '#.*' # in case it's different
$Packages[$Key] = $Package
# e.g. nuget:Google.Apis/1.59.0
if ($Package.Dependencies)
{
Write-Verbose "Installing dependencies for: $Key" -Verbose
$Package.Dependencies |
Sort-Object -Unique |
Install-PackageRecursive #PSBoundParameters
}
if ($Package.Status -eq 'Installed')
{
Write-Verbose "Already installed: $Key" -Verbose
return
}
Write-Verbose "Installing: $Key" -Verbose
$null = Install-Package #Params -Scope $Scope -SkipDependencies -Force:$Force
if ($?)
{
$Package = Get-Package #Params
Write-Verbose "Installed $Key to '$(Split-Path $Package.Source)'." -Verbose
$Packages[$Key] = $Package
$Package
}
}
}
After getting that done, I found that all packages have to be imported before you can use any:
[ValidateSet('net45', 'netstandard1.3', 'netstandard2.0')]$Framework = 'net45'
$ImportOrder = (
'Newtonsoft.Json',
'Google.Apis.Core',
'Google.Apis',
'Google.Apis.Auth',
'Google.Apis.Calendar.v3'
)
$Packages = $ImportOrder | ForEach-Object {Get-Package $_}
$Packages | ForEach-Object {
$Folder = $_.Source |
Split-Path |
Join-Path -ChildPath lib |
Join-Path -ChildPath $Framework
$Path = Join-Path $Folder "$($_.Name).dll"
Add-Type -Path $Path
}
Then it's showtime:
> [Google.Apis.Calendar.v3.CalendarService]::new
OverloadDefinitions
-------------------
Google.Apis.Calendar.v3.CalendarService new()
Google.Apis.Calendar.v3.CalendarService new(Google.Apis.Services.BaseClientService+Initializer initializer)
