openIMAJ 缺少 class 或错误的库

Question

我正在做 this，但我遇到了问题。

这是我的代码

package vid;

import java.io.File;

import org.apache.log4j.BasicConfigurator;
import org.openimaj.image.MBFImage;
import org.openimaj.video.Video;
import org.openimaj.video.xuggle.XuggleVideo;

public class Movie{

    public static void main(String[] args){
        BasicConfigurator.configure();
        Video<MBFImage> video;
        video = new XuggleVideo(new File("in.flv"));

        for (MBFImage mbfImage : video) {
            //something
        }
        video.close();
    }   
}

当我运行它时，我很兴奋

还有我的 pom.xml (long, so I saved it on pastebin). There is a lot on dependencies to different parts of openIMAJ because I've lost track which does what. I've tried to download libs following this，但是当我添加除核心以外的任何内容时，我得到

Missing artifact org.openimaj:video:jar:1.0.6-SNAPSHOT

上一个站点提供的库与 Maven 中央存储库中的库不同。所以，我的问题是，我在哪里可以找到所需 class 的库（或者 MCR 中的哪一个可以提供帮助）？或者与 openIMAJ 网站上的教程兼容的库。

感谢您的帮助

为什么定义<sourceDirectory>src</sourceDirectory>？这样不使用 Maven 广泛接受的默认值 ${project.basedir}/src/main/java.

OpenIMAJ Wiki page's latest update is from Sep 2012. I'd go with the latest release version 1.3.1 from Sep 2014 on Maven Central.

如果你真的想使用快照：core 的 1.0.6-SNAPSHOT 版本是 2013 年的。还有一个 1.4-SNAPSHOT which is just about one month old. This probably applies to other core-... libs。我建议使用最新的。
