将处理库导入eclipse时无法编译 [英] Cannot compile when importing Processing library into eclipse

问题描述

我正在尝试使用eclipse中的Processing库来构建程序。该过程应该相对简单，但是我什至不能编译一个空的处理程序。我不确定问题可能与我的类路径有关。我试图导入处理库并在Eclipse和IntelliJ上多次编写简单程序，但都没有运气。

I am trying to build a program using the Processing library in eclipse. The process should be relatively straightforward but I cannot compile even an empty processing program. I think the problem may be something to do with my classpaths, I'm not sure. I have attempted to import the processing library and write the simple program several times on both Eclipse and IntelliJ with no luck.

这是程序：

import processing.core.PApplet;

public class Processing extends PApplet {

   public static void main(String[] args) {
       PApplet.main("Processing", args);

   }
}

这些是我得到的错误：

These are the errors I get:

我已经卸载了Java JDK并重新安装了它，但没有任何区别。在这个问题上的任何帮助将不胜感激，我似乎无法在网上找到其他人也有完全相同的问题。

I've uninstalled the java JDK and reinstalled it but it did not make a difference. Any help on this issue would be greatly appreciated, I cant seem to find anyone else online with the exact same problem.

推荐答案

I升级到JDK 9后遇到了完全相同的问题。我在这里将其报告为问题（ https：/ /github.com/processing/processing/issues/5371 ），并收到有关处理3与v9不兼容的确认。目前，唯一的解决方法是降级到v8。

I had the exact same problem after upgrading to JDK 9. I reported it as an issue here (https://github.com/processing/processing/issues/5371), and received confirmation that Processing 3 is incompatible with v9. For now, the only workaround is to downgrade to v8.
