Hello, sorry for the long title !
I am a java gradle and idea newbie.
I’d like to build a JavaFX project, I’ve selected Gradle for project build and I get the following error message building the project ( I use idea Community 2023.2.2 on WSL2 with ubuntu 22.04 ) :
Unsupported class file major version 65
Further details are given in a side window:
Your build is currently configured to use Java 21 and Gradle 8.5.
- Use Java 20 as Gradle JVM: Open Gradle settings
- Open Gradle wrapper settings, change
distributionUrlproperty to use compatible Gradle version and reload the project
I don’t want to step back towards Java 20 or older version as I would like to stick to java 21 which is a LTS version.
According to some Gradle manual, Gradle version 8.5 should be ok for java21 Compatibility Matrix
Here is my Gradle-wrapper-properties file:
In Settings >Build, Execution, Deployment > Build Tools > Gradle
in Gradle Projects section:
Build and Run__________________________________
Build and run using: Gradle(Default)
Run tests using: Gradle( Default)
Gradle JVM openjdk21 Oracle OpenJDK
Does someone knows how to fix that ?
Thanks very much for your help !
