所以我尝试使用名为preferencesfx的库，它使用fontawesomefx，抛出以下错误。

Exception running application my.package.Main

我在glyphs工厂类的第62行找到了问题的原因，但我不知道如何修复它。
方法 GlyphsFactory.class.getResource(pathToIconFont) 退货 null ，而不是返回字体文件。我可以看到该方法是通过路径加载字体文件 /de/jensd/fx/glyphs/fontawesome/fontawesome-webfont.ttf （这似乎是正确的）。我可以看到字体是从软件包中加载的 de.jensd.fx.glyphs.fontawesome Package de.jensd.fx.glyphs 但两个包裹装在不同的jar里。

知道为什么吗 getResource() 退货 null ? 我向开发人员报告了它，但似乎fontawesomefx库被放弃了。
我用最新的intellij在MacOSX上运行这个。
