.jar计划中的Nosuchmethoderror [英] Nosuchmethoderror in .jar program

问题描述

你好，



我用netbeans编写了一个maven项目。当我在Netbeans中运行程序时，一切正常。在构建项目并使用以下命令运行Jar文件：java -jar filename.jar之后程序启动，但是当我现在执行以下一个函数时，我将得到一个

Hello,

I have written a maven project with netbeans. When I run the program in Netbeans everything works. After building the project and running the Jar file with: java -jar filename.jar the program starts, but when I now execute one following function, I'll get a

java.lang.NoSuchMethodError:

例外。所有其他功能都在工作。



我尝试过：



例外：

exception. All the other functions are working.

What I have tried:

The Exception:

Extra Bytebuffer:
ByteBuffer length =217
Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError: java.nio.ByteBuffer.position(I)Ljava/nio/ByteBuffer;
	at humer.kamera.PhraseUvcDescriptor.phraseUvcData(PhraseUvcDescriptor.java:116)
	at humer.kamera.CameraSearch.listDevice(CameraSearch.java:143)
	at humer.kamera.CameraSearch.autoSearchTheCamera(CameraSearch.java:85)
	at humer.kamera.Kam.AutoSearchTheCamerasActionPerformed(Kam.java:385)
	at humer.kamera.Kam.access$100(Kam.java:45)

	at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:402)
	at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:259)

	at javax.swing.plaf.basic.BasicMenuItemUI.doClick(BasicMenuItemUI.java:842)
	at javax.swing.plaf.basic.BasicMenuItemUI$Handler.mouseReleased(BasicMenuItemUI.java:886)

Exception来自这个ByteBuffer：

The Exception comes from this ByteBuffer:

public PhraseUvcDescriptor (ByteBuffer data) {
        this.uvcData = ByteBuffer.allocate(data.limit());
        this.uvcData = data.duplicate();
    }

当我设置ByteBuffer的位置时：

And when I set the Position of the ByteBuffer:

        positionAbsolute += descSize;
        uvcData.position(positionAbsolute);

}

我将获得例外：

I'll get the Exception:

uvcData.position(positionAbsolute);

= 116行



我不喜欢不知道，为什么ByteBuffer不能在Jar文件中工作，因为在Netbeans中一切正常。



谢谢，



Peter

= Line 116

I don't know, why the ByteBuffer isn't working in the Jar file, because in Netbeans everything works.

Thanks,

Peter
