Skip Java dependency updated from JDK17 to JDK21

[marcprux]

We have released Skip 0.8.10, along with skip-unit 0.6.0, which updates the Skip Java dependency from JDK 17 to JDK 21 by way of skip-unit's skip.yml dependency specification. Java 21, which is a long-term support (LTS) release, has been the default for Homebrew for a few months now, but Gradle did not support it well until 8.6 was released.

This update should be transparent for users who update their Skip packages using Xcode's File / Packages / Update to Latest Package Versions. In fact, initial builds should be faster and more robust, due to the no longer needing to "auto-provision" (i.e., download) a separate JDK 17 install when it is not already installed.

Please do let us know if you encounter issues that seem related to the Java update. Happy Skipping!

I can't build anymore since upgrading. I've also tried making a fresh project and same issue when I try to build from Xcode. Oddly if I open the Android project directly in AndroidStudio it builds fine.

openjdk version "21.0.1" 2023-10-17

I keep getting this error:

Can you try manually setting the project to use JDK 20 or 21 in the Settings > Build, Execution, Deployment > Build Tools > Gradle setting section, as per this screenshot:

Please let us know if this works. Ideally, we will be able to set it for you – we will look into it.

@marcprux I had already tried that and it still wasn't working, but for anyone else that gets stuck on this error, it was actually that I needed to update gradle, running brew install gradle resolved it for me
