firebase-tools no longer supports Java version before 11. Please upgrade to Java version 11 or above to continue using the emulators

Question

I have version 11.0.1 of firebase installed on my Windows 11 machine. When I run the firebase emulators, it crashes with this message:

$ firebase emulators:start

!! emulators: firebase-tools no longer supports Java version before 11. Please upgrade to Java version 11 or above to continue using the emulators. i emulators: Shutting down emulators.

Error: firebase-tools no longer supports Java version before 11. Please upgrade to Java version 11 or above to continue using the emulators.

I try to update my Java but it says I have the latest version:

I check what version I have and it says version 8... though I need 11? I'm confused:

I try checking the version in the CLI and I get even more confused:

$ java -version
java version "1.8.0_333"
Java(TM) SE Runtime Environment (build 1.8.0_333-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.333-b02, mixed mode)

My questions are:

1. How can I get my firebase emulators to run again?
2. What version of Java do I have? 11? 8? 1.8?
3. How can I upgrade to the latest version of Java?

Answer 1

I just had the same error and just went through the all version 8 vs. version 11, etc. but now I get it.

firebase-tools is referring to the version of the JDK installed, not the version of Java runtime installed.

The latest JDK from Oracle can be downloaded from https://www.oracle.com/java/technologies/downloads/#jdk18-mac with the latest version being 18.

The Java runtime for Mac latest version is indeed 8, but again that's not what firebase tools is looking for
