I am getting a bunch of objective-c errors when trying to run make javakit-run (see below)

I am one an M3 MacBook Air.

This is java --version:

openjdk 23.0.1 2024-10-15
OpenJDK Runtime Environment (build 23.0.1+11-39)
OpenJDK 64-Bit Server VM (build 23.0.1+11-39, mixed mode, sharing)

Java was installed with brew (openjdk) and JAVA_HOME is pointed at /Users/REDACTED/Library/Java/JavaVirtualMachines/openjdk-23.0.1/Contents/Home

This is swift --version:

Apple Swift version 6.1-dev (LLVM c7635515f932833, Swift dbf388c0a58df0e)
Target: arm64-apple-macosx15.0

Here are the errors:

Hi there, thanks for trying out the project and sorry about the current state of the build, we're ironing out things and trying to get away make driving things.

Specifically for this sample, please follow the readme: https://github.com/swiftlang/swift-java?tab=readme-ov-file#javakit-swift---java

JavaKit (Swift -> Java)

To run a simple app showcasing a Swift process calling into a Java library you can run:

cd Samples/JavaKitSampleApp
swift build
java -cp .build/plugins/outputs/javakitsampleapp/JavaKitExample/destination/JavaCompilerPlugin/Java -Djava.library.path=.build/debug com.example.swift.JavaKitSampleMain

rather than rely on the make task; I'll remove the make task so it's not confusing folks anymore
