I’ve a rust library that I want to call from Java.
I’ve managed to create the corresponding .h-file and extract from that the Java bindings.
As long as my project structure looks like the following, I can access the c-function when compiling and starting the program with

javac --source=22 -d . src/my/panama/java/project/name/*.java
java --enable-native-access=ALL-UNNAMED Main.java

├── Cargo.lock
├── Cargo.toml
├── Main.java
├── my
│   └── panama
│       └── java
│           └── project
│               └── name
│                   ├── projectPanamaFiles.class
├── libmy_rust.dylib
├── my_rust_lib.h
└── src
    ├── my
    │   └── panama
    │       └── java
    │           └── project
    │               └── name
    │                   ├── projectPanamaFiles.java
    ├── lib.rs
    └── custom_functions.rs

Now I want to integrate the native library to my main project (Micronaut 4.4.2 & Java 22) with a structure looking like:

── src
    └── main
        ├── java
        │   └── my
        │       └── panama
        │           └── java
        │               └── project
        │                   └── name
        │                       └── Application.java
        └── rust
            ├── same As above

When I place all of the .class files of the Panama binding in src/main/java/my/Panama/java/project/name/library, I can use them in IntelliJ as every other library.

When I try to run my app, it fails with java.lang.IllegalArgumentException: Cannot open library: libprocess_dlms.dylib.
I’ve tried adding it via gradle.kts via implementation(fileTree("src/main/rust")) but nothing changed.
Also adding it directly via System.load("/absolute/path/to/libmy_rust.dylib"); results in the same error message.
