The error tells you, that you tried to run a Gradle 7.5 build using Java 21 which is not supported: [Compatibility Matrix](https://docs.gradle.org/current/userguide/compatibility.html) ---

Well, if Fusion does everything for you, why are you asking in a Gradle forum? Ask in a Fusion community, I don’t even know or care what that tool is. The error tells that you use Gradle 7.5 and Java 21 and that is not a legal combination. Either use a newer Gradle version that is compatible with your Java version or use an older Java version that is compatible with your Gradle version. ---

Yeah, that’s an unlucky message the Gradle folks added there. It comes for each and every build. Even if you write illegal code and thus get a compiler error, this non-sense is displayed. But well, actually you have a Gradle problem and I explained you what your problem is. How you control your environment, especially if a tool does it for you, is not a Gradle topic though. 🙂
