Create a Custom Detection Script for Java 9 Development Kit (PowerShell)

Microsoft Endpoint Manager Configuration Manager (MEMCM / SCCM) and Microsoft Intune use Detection Rules to determine the presence of Applications & Win32 Apps. The detection rules ensure that application installations only begin to run if the application is not already installed on the device. This article will serve as an informative guide and give you a clear understanding of how to create an updated custom detection script for each new version of the Java 9 Development Kit using PowerShell.

How to Create a Custom Detection Script for the Java 9 Development Kit

Java 9 Development Kit 64-bit (Registry Detection Method)

  • Install the version of Java 9 Development Kit 64-bit you want to deploy on a test box or VM
  • Open Windows PowerShell ISE by Right-Clicking on Windows PowerShell ISE and selecting Run as Administrator
  • Copy the following code into the Windows PowerShell ISE
## Check for Java 9 Development Kit 64-bit (Registry Detection Method)
$Java = Get-ChildItem -Path "HKLM:\SOFTWARE\Classes\Installer\Products" -ErrorAction SilentlyContinue | Get-ItemProperty | Where-Object {$_.ProductName -like 'Java*SE Development Kit 9*' } | Select-Object -Property ProductName, PSChildName
$Java.ProductName
$Java.PSChildName

## Create Text File with Java 9 Development Kit 64-bit Registry Detection Method
If(Test-Path "HKLM:\SOFTWARE\Classes\Installer\Products\$($Java.PSChildName)") { 

$FilePath = "C:\Windows\Temp\Java_9_JDK_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If((Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Classes\Installer\Products\$($Java.PSChildName)' -Name ProductName -ea SilentlyContinue) -eq '$($Java.ProductName)') {"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath 
}
  • Click Run Script (F5)
  • A text file will open with the Java 9 Development Kit 64-bit Detection Method script required to detect the current version of Java 9 Development Kit that is installed on the device you are running the script from.

Example:

If((Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Classes\Installer\Products\36478FE1F0B0A2B51B76225BDC73A1DC' -Name ProductName -ea SilentlyContinue) -eq 'Java(TM) SE Development Kit 9.0.4 (64-bit)') {
Write-Host "Installed"
}

Always make sure to test everything in a development environment prior to implementing anything into production. The information in this article is provided “As Is” without warranty of any kind.
