What Version of Java do I need for My Version of Minecraft?

Different versions of Minecraft typically need different versions of Java, as Mojang has updated Minecraft’s Java requirements over the years.

At AleForge, we ship our servers with a custom Java install that allows Java 21 to be used on all versions, so you do not need to worry about Java versions for your Minecraft server in most cases. We offer specific versions for modpacks and plugins that rely on the specific functionality of older editions of Java.
