Disregard... as soon as I posted this, I found a script that appears to work.

I know this has been discussed several times, but I wanted to throw my 2 cents in... I wrote a script to install and update Java. This version only does the JRE, although I'm sure you could expand it to do the JDK also.

1#!/bin/sh

3# Get the latest version of Java

5minorver=`echo $javaver | grep -o '...$'`

7# Get build number (counting down from 20), since I can't find anywhere that Oracle publishes this in an easily-findable place
8b=20
9while [ $b -gt 1 ] ; do
10  echo "Build number $b"
11  filename="jre-8i$minorver-macosx-x64.dmg"
12
13  curl -j -k -L -H "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u$minorver-b$b/96a7b8442fe848ef90c96a2fad6ed6d1/jre-8u$minorver-macosx-x64.dmg > $filename
14
15  # Check the file size of the download
16  minsize="500000"
17  filesize=$(wc -c <"$filename")
18
19  # If the file is larger than 500kb, assume it's the real dmg
20  if [ $filesize -ge $minsize ]; then

30
31# Install
32sudo installer -pkg /Volumes/Java 8 Update $minorver/Java 8 Update $minorver.app/Contents/Resources/JavaAppletPlugin.pkg -target /
33
34# Remove DMG
35rm jre-8i$minorver-macosx-x64.dmg
36
37# Unmount DMG
38diskutil umount /Volumes/Java 8 Update $minorver

I'm positive it can be dramatically improved, but even though there are dozens of threads about it, I couldn't find a script that worked for me.

@omatsei

I tried testing your script out. I have a solid JDK solution but I'm looking for a JRE option. It errors out with the following after the download. I do see it writing this file to the directory the script is executed in jre-8i191-macosx-x64.dmg .

hdiutil: attach failed - image not recognized
installer: Error - the package path specified was invalid: '/Volumes/Java 8 Update 191/Java 8 Update 191.app/Contents/Resources/JavaAppletPlugin.pkg'.
Unmount failed for /Volumes/Java 8 Update 191

For anybody that cares, I put together this script that checks the latest version of Java against the currently installed one, if there is. If they don't match, it downloads the latest version of Java and installs it.

It's a mash up of these other scripts plus the ideas that @omatsei had in the OP:

I have a hard time with Patch Management Policies because I manage labs and there is no way to set a maintenance window like in normal policies. I can't have these things go off in the middle of class.

@jared_f Just speculating, but with the changes in license requirements for JRE 8.x, the script may need to be revised. (JRE no longer authorized for commercial use without a license). I'm unable to manually download it without logging into an Oracle account first.

Just confirming that after I got things working using this script in late February it is now broken. I've confirmed—as best I can—that it is a login issue. Without being logged in you cannot download the packages/installers so the scripted system no longer works. We are experimenting with changes and I'm reading the fine print from Oracle to see how we might move forward (although there's nothing in their license that seems to prevent distributing Java SE yourself as long as you don't modify it).

Nice work! Also for what it is worth I cleaned up some syntax in the sctipt, tested on my 10.14.6 (beta) system and it ran very well.

This is the script output from my system:

I wanted to post the script but having a hard time, sorry.

Your right there is some login to the site that prevents the package from being downloaded.

I tested part of the url and latest site parts of the scipt there is a login that is needed.

Oh well.

dvasquez, can you copy the cleaned as plain txt up script into the response window. I'm getting the same error messages as the others but curious to see how your script was written.

Does anyone else have a recommended method for pushing out/updating Java?

We evaluated our needs for Java JRE and found that it is no longer required for anything that our users do (at least not that is required for their work). Java is only required for either use by IT staff or backend servers so our solution was to completely uninstall the Java JRE from all user systems and we are able to easily manually manage the remaining systems. For us this put a nail in the coffin for Java JRE on the user side and it is also a big security win as it reduces vectors for exploits/malware/viruses.
