Java Versions

What is Java?

Java is the software platform required to run Minecraft servers. Minecraft is built using specific versions of Java. If the versions do not match, the server will crash or refuse to start. You must use the correct Java version for your specific Minecraft version.

What Java version should I use?

Minecraft Version	Java Version	Download
26.1+	Java 25	Adoptium

SquidServers provides Java JDKs. However, if you have issues or these do not work for your specific case, we recommend Eclipse Temurin JDKs. All versions listed above link to the official Adoptium site, which includes an installation guide for each version and OS.
