Unsupported class file major version 67

Help/Discuss
1

As soon as Gradle finish init I got this problem in VSC

The supplied phased action failed with an exception.
Build completed with 1 failures.
BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 67
Unsupported class file major version 67

I’m using the command

gradle init --type java-application --java-version 23 --project-name Name --dsl groovy --split-project --incubating --no-comments

java version: 23.0.1
gradle version: 8.12

You are most likely not using the Gradle version you think you are using but instead one that is not compatible with Java 23.

How do I verify it properly?

4

Use --version with the invocation.

Can you provide a build --scan URL of the failing run?

https://scans.gradle.com/s/ojfddlnjnkl4i

That’s a build scan of a successful invocation, not of the erroring build.

I noticed it too, so I just cleared the dir again and gradle init again with same configs. Now I got no problems at all. I did it at least 8 times before. I have no idea why this time it is all right.

Thank you for helping me.
