How to download and install JRE with PowerShell for Sitecore Solr installation

Question

The script from Jeremy Davis Downloads, installs, adds SSL and sets up Solr as windows service. However, JRE is required for Solr and JRE needs to be installed manually. Is there anyway to download and install JRE with PowerShell?

Answer 1

Actually, I did find out a way to download and install JRE with PowerShell script.It is really use-full therefore I wanted to share it here in StackExchange. This script can be optimized but it does the job as it is.

Below is the entire script: https://github.com/erjan123/Sitecore/blob/master/Sitecore/PowershellScripts/Sitecore%20Solr/2.install-solr-7.5-and-JRE.ps1

I have also a tutorial that explains the script: https://www.youtube.com/watch?v=3-27syl8C98&t=10s

Param(
    $downloadInstallJRE = $true,
    $JREVersion64 = $true  
)

if($downloadInstallJRE -eq $true)
{
    if($JREVersion64 -eq $true)
    {
        $URL=(Invoke-WebRequest -UseBasicParsing https://www.java.com/en/download/manual.jsp).Content |     ForEach-Object{[regex]::matches($_, '(?:<a title="Download Java software for Windows \(64-bit\)" href=")(.*)(?:">)').Groups[1].Value} 
    }
    else
    {       
        $URL=(Invoke-WebRequest -UseBasicParsing https://www.java.com/en/download/manual.jsp).Content | ForEach-Object{[regex]::matches($_, '(?:<a title="Download Java software for Windows Online" href=")(.*)(?:">)').Groups[1].Value}
    }
        Invoke-WebRequest -UseBasicParsing -OutFile jre8.exe $URL
        Start-Process .\jre8.exe '/s REBOOT=0 SPONSORS=0 AUTO_UPDATE=0' -wait

    if($JREVersion64 -eq $true)
    {
        $JREVersion = Get-ChildItem -Path "C:\Program Files\Java" -name | Where-Object { -not $_.PsIsContainer } | Sort-Object LastWriteTime -Descending | Select-Object -first 1 

        Write-Host "JREVersion: $JREVersion"
        $JREPath = "C:\Program Files\Java\$JREVersion"
        Write-Host  "JREPath" + $JREPath
        Write-Host "Downloading 64 bit of JRE"
    }   
    else{

        $JREVersion = Get-ChildItem -Path "C:\Program Files (x86)\Java" -name | Where-Object { -not $_.PsIsContainer } | Sort-Object LastWriteTime -Descending | Select-Object -first 1 

        Write-Host "JREVersion: $JREVersion"
        $JREPath = "C:\Program Files (x86)\Java\$JREVersion"
        Write-Host  "JREPath " + $JREPath
        Write-Host "Downloading 32 bit of JRE"
    }

        Write-Host "JRE package URL " $URL
}

Annoyingly you can no longer scrape the page as in the accepted answer and need to grab the URL manually first.

$URL="https://javadl.oracle.com/webapps/download/AutoDL?BundleId=244422_26081f2c2d854520a890cbbc4a1d8fee"
Invoke-WebRequest -UseBasicParsing -OutFile jre8.exe $URL

Start-Process .\jre8.exe '/s REBOOT=0 SPONSORS=0 AUTO_UPDATE=0' -wait

$JREVersion = Get-ChildItem -Path "C:\Program Files\Java" -name | Where-Object { -not $_.PsIsContainer } | Sort-Object LastWriteTime -Descending | Select-Object -first 1 

Write-Host "JREVersion: $JREVersion"
$JREPath = "C:\Progra~1\Java\$JREVersion"
Write-Host  "JREPath" + $JREPath
Write-Host "Downloading 64 bit of JRE"


Write-Host "JRE package URL " $URL
