Forcing nopCommerce to Re-install Your Plugin on Build

When developing a plugin for nopCommerce, it is a bit of a hassle to uninstall and reinstall your plugin over and over as you add new features.  Since nopCommerce stores the list of plugins and their statuses (installed, install-pending, etc), I thought it would be more convenient to force a re-install every time you build your project.  

The key is to add a post-build script.  I’ve implemented one in PowerShell:

Forces your plugin to reinstall by modifying the web project's plugins.json.  By Hobbes Pirakitti of Balta Development /

To use:

    1) Add this file to the root of your project as ForceReinstall.ps1
    2) Customize the $pluginName variable below
    2) To your .csproj, add the following
          <Target Name="PostBuild" AfterTargets="PostBuildEvent">
            <Exec Command="powershell $(ProjectDir)ForceReinstall.ps1" />

$pluginName = 'Misc.YourPluginName';

####### end configurable #######

$ErrorActionPreference = 'Stop';
$pluginJsonPath = Join-Path $MyInvocation.MyCommand.Source '..\..\..\Presentation\Nop.Web\App_Data\plugins.json' -Resolve;
$pluginString = Get-Content $pluginJsonPath -Raw;
$pluginJson = ConvertFrom-Json $pluginString;

$installedPlugins = [System.Collections.ArrayList]($pluginJson.InstalledPluginNames)
$pluginJson.InstalledPluginNames = $installedPlugins.ToArray();

if ($pluginJson.PluginNamesToInstall.Where({$_.Item1 -eq $pluginName}).Count -eq 0) {
    $pluginsToInstall = [System.Collections.ArrayList]$pluginJson.PluginNamesToInstall;
        "Item1" = $pluginName;
        "Item2" = $null # "Customer GUID"
    $pluginJson.PluginNamesToInstall = $pluginsToInstall;

$pluginJson | ConvertTo-Json -Depth 10 > $pluginJsonPath;

The instructions are in the script. Enjoy!
