Java JAR file runs on local machine but missing file on others

Question

The JAR file consists of the ffmpeg.exe file and it can run normally on my machine without any problems. However, if I try to run it on another computer it would tell me that java.io.IOException: Cannot run program "ffmpeg.exe": CreateProcess error=2,The system cannot find the file specified from the stacktrace. The way I imported it was

FFMpeg ffmpeg = new FFMpeg("ffmpeg.exe");  //in res folder

...
//ffmpeg class
public FFMPEG(String ffmepgEXE) {
    this.ffmepgEXE = ffmepgEXE;
}

Answer 1

The quick fix is you have to put ffmpeg.exe in the same folder with your .jar file.

If you want to read file from resources folder, you have to change this code:

URL resource = Test.class.getResource("ffmpeg.exe");
String filepath = Paths.get(resource.toURI()).toFile().getAbsolutePath(); 
FFMpeg ffmpeg = new FFMpeg(filepath);
