Hi,
I’m trying to get processing working within the context of a java project. So far I’ve succesfully managed to pull in processing-core using maven, but I’m struggling with processing-video. I am a total noob when it comes to the whole java ecosystem, so I might just be fumbling some basics here…
My pom.xml looks like this:

I’m symlinking the video jar from Processing’s sketchbook/library/video/library/video.jar into the dependencies directory in my project. I suspect that this is one of the places where things go wrong…
The main file I’m trying to compile looks like this:
package com.roosnaflak;
import processing.core.PApplet;
import processing.video.*;
public class App extends PApplet
{
Movie movie;
public void settings() {
size(640, 480);
background(0);
movie = new Movie(this, "/home/kf/Videos/100-sketches-May/hands.mp4");
movie.loop();
}
public void movieEvent(Movie m) {
m.read();
}
public void draw(){
// background(0);
// ellipse(mouseX, mouseY, 20, 20);
image(movie, 0, 0, width, height);
}
public static void main(String[] args){
String[] processingArgs = {"MySketch"};
App mySketch = new App();
PApplet.runSketch(processingArgs, mySketch);
}
}
which gives me this error:
