NoSuchMethodError

[NeariX67]

Hey,
i wasnt quite able to make this project runable.

Neither implementation example of your readme seem to work for me.

Here's my Class:

package com.nearix.test;

import java.util.Collection;
import java.util.List;

import de.matthiasfisch.mysticlight4j.Device;
import de.matthiasfisch.mysticlight4j.LED;

import de.matthiasfisch.mysticlight4j.api.MysticLightAPI;

public class Main {
public static void main(String[] args) {
MysticLight4j mysticLight = new MysticLight4j();
Collection devices = mysticLight.getAllAvailableDevices();
for (Device device : devices) {
String id = device.getIdentifier(); // Unique ID of the device
String name = device.getName(); // Display name of the device
System.out.println(name);
List leds = device.getLEDs(); // The LED groups on the device
}

// Console:

	MysticLightAPI.initialize();  
	DeviceInfo[] devices = MysticLightAPI.getDeviceInfo();  
	for (DeviceInfo device : devices) {  
	    // Prints the unique identifier of the device  
	  System.out.println(device.getDeviceType());  
	  System.out.println("LED groups for this device:");  
	 for (int i = 0; i < device.getLedCount(); i++) {  
	        LedInfo led = MysticLightAPI.getLedInfo(device.getDeviceType(), i);  
	  System.out.println(led.getName());  
	  }  
	}

}

}

It doesn't seem to find the getLedInfo Method.

Hi NeariX67,

unfortunately I could not reproduce the issue. It is weird that the native methods were first found during initialization and retrieval of the device infos, but the getLedInfo method was not.

I created a repository with an example usage of the native API that is working for me: https://github.com/fischmat/mysticlight4j_example
Please note that you need to download the Mystic Light SDK from here and put the DLLs in the same folder as the native DLLs (as I can't push the proprietary binaries here).
Also make sure that the place where your DLLs are located is the working directory of your run configuration.
I recompiled the mysticlight4j_native.dll and mysticlight4j_native_x64.dll and pushed them to develop. They can be found here and here respectively.

Please let me know if you're able to get the example project running.

Bests,

Matthias

--Wolte nur den Issue auf Englisch schreiben falls es noch jemanden mit dem Problem gibt

Hab mal dein Example getestet, geht ebenso nicht:
Console:
MPG Z490 GAMING PLUS (MS-7C75)
Exception in thread "main" java.lang.NoSuchMethodError:
at de.matthiasfisch.mysticlight4j.api.MysticLightNativeBinding.getLedInfo(Native Method)

at com.nearix.test.Main.main(Main.java:19)

Meine Libraries:
commonds-lang3-3.10.jar
guava-29.0-jre
jsr305-3.0.2
lombok

SDK Files:
MysticLight_SDK.dll
MysticLight_SDK.h
MysticLight_SDK_x64.dll
mysticlight4j_native.dll
mysticlight4j_native_x64.dll

Kannst du mir vllt mal die MysticLight SDK Dateien hochladen? Vielleicht verwenden wir eine unterschiedliche Version. Andernfalls kann ich mir das echt nicht erklären.
Mfg
