This library isn't working.

首先，在 Processing 3.5.4 中从下载的 zip 重现安装过程，并检查归档中的库和 JAR 命名。确认 package import 和依赖项布局，然后验证干净安装是否会出现在 Import Library 中，且不会出现竞争库错误。

I downloaded the zip file and extracted it all into a new folder in "libraries" in my Processing folder, but when I would type "import processing.OpenSimplexNoise.*;" I got the message "The import processing.OpenSimplexNoise cannot be resolved." I discovered that this was because the library and JAR file didn't have the same name, and the "lib" folder should be "library."
I fixed these two issues, and then OpenSimplexNoise appeared in the Import Library menu, but when I did, a bunch of code appeared:

import japplemenubar.*;
import processing.awt.*;
import processing.core.*;
import processing.data.*;
import processing.event.*;
import processing.javafx.*;
import processing.opengl.*;

and the error message:

More than one library is competing for this sketch
The import japplemenubar points to multiple libraries:
core (C:\Program Files\Processing\processing-3.5.4\core)
OpenSimplexNoise (C:\Users**\Documents\Processing\libraries\OpenSimplexNoise)
Extra libraries need to be removed before this sketch can be used.

As far as I can tell, I haven't done anything incorrectly, and whatever's happening here is probably far beyond my understanding.
