jdeploy-bundle path in Runtime Arguments

[Skepller]

My project requires setting the java.library.path System property to the native libraries' location. I am copying these libraries using "files": [{"dir": "native-libs"}], which places them in the jdeploy-bundle folder alongside the jar in the final deploy.

I was trying to set it with the Runtime Arguments, but "args": ["-Djava.library.path={{ app.path }}"] resolves to the executable's path, not the jdeploy-bundle folder where the files are copied.

It's not an issue at runtime, I can get the jar's path to find other files with:

File jarFile = new File(ClassName.class.getProtectionDomain().getCodeSource().getLocation().toURI());
return jarFile.getParentFile().getAbsolutePath();

My problem is that, for the native libraries, I need to set java.library.path before launching the app.
Is there an "official" solution to get the jdeploy-bundle folder path in the Runtime Arguments? Something like a placeholder would be awesome, but I don't know if it's possible under the hood.

I don't currently have a placeholder for the jdeploy-path, but I can add it. Please file an RFE in the issue tracker.

It it rare that I needed to set the java.library.path, I usually bundle my native libs inside my jars, and load them at runtime.

Here is a chat gpt prompt that outlines a sample solution to that: https://chatgpt.com/share/6835aab2-cdb8-8003-8eb2-6492282c66ff

Oh yes, I should have clarified that this is a stupid requirement from a library that my app uses. They just have a System.loadLibrary() inside a static block.

The library is open-source, so I was considering changing the lib source code and recompiling, but I didn't go for it to avoid a cumbersome update process every time I upgrade it. This java.library.path already caused me so much trouble.

I created the Issue #184

And thanks for the prompt response and willingness to help, man!

Also, jDeploy is awesome! I didn't see any obvious way to support the project, you should definitely set up a "Buy me a coffee" or similar!
