Java Updater

Motivation

I have a bunch of computers (mostly Windows) with a couple of different Java versions to maintain. It is cumbersome to download all new versions on all computers, unpack und replace that Java versions.

Configuration

TBW: describe yaml

Available variables

• JU_CONFIG_ARCH
• JU_CONFIG_TYPE
• JU_CONFIG_VENDOR
• JU_CONFIG_VERSION

NOTE: The variables used for the directory are not prefixed with env.!

Scheduling (Windows)

Run as Administrator

schtasks /create /tn "Update Java Installations" /tr "<path/to/java-update.exe> --config <path/to/config>" /sc onlogon

This will run the Java Updater each time the user logs on.
