Provided GUI jar does not work on Linux and MacOS.

[Acuadragon100]

Problem:

The application only includes the native skiko library for the current operating system.
This means that the version up for download (which was built for Windows) only includes the dll libraries for Windows x64 and therefore does not work on Linux and MacOS.

Full Error:

Exception in thread "main" java.lang.ExceptionInInitializerError

Suggested Solution:

Change the gradle configuration of the GUI application to bundle compose for all operating systems and architectures rather than just the current operating system. Alternatively build multiple binaries for different operating systems and architectures.

Workaround for users:

Option 1:

1. Download the awt-runtime jar file for your operating system from https://github.com/JetBrains/skiko/releases/.
2. Extract the .so, .dll or .dylib files as well as the .sha256 files.
3. Insert the extracted files into the jNeedle GUI jar file.

Option 2:

Compile the application yourself.
