当Eclipse IDE与Arduino接口时,Java运行时环境::检测到一个致命错误

当Eclipse IDE与Arduino接口时,Java运行时环境::检测到一个致命错误,java,eclipse,arduino,rxtx,Java,Eclipse,Arduino,Rxtx,我在EclipseIDE与Arduino接口时遇到了问题。我已经完成了在Arduino和Eclipse IDE之间进行通信所需的所有过程(比如安装Rxtx.jar和build path,然后在Eclipse工作区文件夹中复制serial.dll和parallel.dll文件…) 我还检查了ArduinoIDE和Eclipse代码中的Arduino COM端口配置 但我还是在Eclipse控制台中收到了这种消息 我的Eclipse IDE Java代码如下: (我的Arduino端口是COM5

我在EclipseIDE与Arduino接口时遇到了问题。我已经完成了在Arduino和Eclipse IDE之间进行通信所需的所有过程(比如安装Rxtx.jar和build path,然后在Eclipse工作区文件夹中复制serial.dll和parallel.dll文件…)

我还检查了ArduinoIDE和Eclipse代码中的Arduino COM端口配置

但我还是在Eclipse控制台中收到了这种消息



我的Eclipse IDE Java代码如下: (我的Arduino端口是COM5,使用windows 10 x64位。)


我的简单Arduino代码如下:

void setup(){
  Serial.begin(9600);
}

void loop(){
  Serial.println("Hello world");
  delay(1000);
}
请给出解决此问题的建议


谢谢。

我对Java 9也有同样的问题,当我改回Java 8时,它就可以工作了。
另一个解决方案,使用它对我有用…

您确定您有适合64位Java的DLL吗?感谢您的建议…从您建议的链接中,我下载了rxtx.jar文件和DLL,并将其替换到工作区中。。。。现在我没有收到RXTX不匹配的警告消息…这是件好事…但整个错误消息的其余部分仍然是原来的@PURVILVAGHELA这个问题仍然是一个悬而未决的问题,因为您接受的答案没有解释这个错误的原因。请不要接受不完整的答案。可能重复我在OpenJDK 11中遇到的jSerialComm同样的问题您可以报告一个错误,希望他们能找到解决方案you@alex_z您可能需要查看以下内容:
