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.MysticLight4j; import de.matthiasfisch.mysticlight4j.api.DeviceInfo; import de.matthiasfisch.mysticlight4j.api.LedInfo; 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: // C:\Users\NeariX\OneDrive - OSZ IMT\Coding\Eclipse\WorkSpace\MSI Mystic Light Java // Exception in thread "main" java.lang.NoSuchMethodError: // at de.matthiasfisch.mysticlight4j.api.MysticLightNativeBinding.getLedInfo(Native Method) // at de.matthiasfisch.mysticlight4j.api.MysticLightAPI.getLedInfo(MysticLightAPI.java:151) // at de.matthiasfisch.mysticlight4j.LED.(LED.java:33) // at de.matthiasfisch.mysticlight4j.Device.lambda$0(Device.java:29) // at java.util.stream.IntPipeline$4$1.accept(IntPipeline.java:250) // at java.util.stream.Streams$RangeIntSpliterator.forEachRemaining(Streams.java:110) // at java.util.Spliterator$OfInt.forEachRemaining(Spliterator.java:693) // at java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:482) // at java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:472) // at java.util.stream.ReduceOps$ReduceOp.evaluateSequential(ReduceOps.java:708) // at java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:234) // at java.util.stream.ReferencePipeline.collect(ReferencePipeline.java:499) // at de.matthiasfisch.mysticlight4j.Device.(Device.java:30) // at java.util.stream.ReferencePipeline$3$1.accept(ReferencePipeline.java:193) // at java.util.Spliterators$ArraySpliterator.forEachRemaining(Spliterators.java:948) // at java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:482) // at java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:472) // at java.util.stream.ReduceOps$ReduceOp.evaluateSequential(ReduceOps.java:708) // at java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:234) // at java.util.stream.ReferencePipeline.collect(ReferencePipeline.java:499) // at de.matthiasfisch.mysticlight4j.MysticLight4j.getAllAvailableDevices(MysticLight4j.java:64) // at com.nearix.test.Main.main(Main.java:13)

    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());  
      }  
    }

// Console: // MSI_MB // LED groups for this device: // Exception in thread "main" java.lang.NoSuchMethodError: // at de.matthiasfisch.mysticlight4j.api.MysticLightNativeBinding.getLedInfo(Native Method) // at de.matthiasfisch.mysticlight4j.api.MysticLightAPI.getLedInfo(MysticLightAPI.java:151) // at com.nearix.test.Main.main(Main.java:25)

}

}

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 de.matthiasfisch.mysticlight4j.api.MysticLightAPI.getLedInfo(MysticLightAPI.java:151) 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
