IntelliJ incorrectly sees projects as Java 8 modules

[Camotoy]

As of this commit: GeyserMC/Geyser@a72e495, I can verify three different Linux computers read the Geyser project as Java 8. Gradle still correctly compiles to Java 16.

Reproduced on IntelliJ versions 2021/2022/2023.

To reproduce should be as simple as cloning the Geyser repository, finding a record class, and noting how IntelliJ doesn't process the class correctly.

Here's the output of uname -a on my current computer:
Linux HOSTNAME 6.2.6-76060206-generic #202303130630~1679424972~22.04~4a8cde1 SMP PREEMPT_DYNAMIC Tue M x86_64 x86_64 x86_64 GNU/Linux
And cat /etc/os-release:

Can reproduce the same issue on Windows 11; also with the Geyser project

Sorry for the delay in getting to this! Just on a hunch, can you still reproduce this issue if you change this line to tasks.withType<JavaCompile>().configureEach {?

i have an unfortunate feeling that this has something to do with eager task realization :(

That indeed solves the issue! For me at least.
But that line isn't even needed because Indra enforces that for us right?
