我曾尝试实施 Substance LAF。我还下载了 Trident 库。应用程序通常会启动（从包结构中选择 LAF），但是当我尝试在其中使用菜单时，出现JMenuBar以下异常。

我发现了非常相似的问题，但它绝对是不同的——Flamingo 功能区：Java.lang.IllegalArgumentException: No interpolator found for java.lang.Float:java.lang.Float。

经过几个小时后，我找到了解决方案。错误

java.lang.IllegalArgumentException：找不到用于 java.lang.Float:java.lang.Float 的插值器

与类中的代码无关TimelinePropertyBuilder。相反，它缺少相应顶级库中的trident-plugin.properties文件。META-INF确切地定义了插值器类源。

因此，与其寻找它，不如说这是非常需要的trident-plugin.properties：

UIToolkitHandler=org.pushingpixels.trident.swing.SwingToolkitHandler
PropertyInterpolatorSource=org.pushingpixels.trident.swing.AWTPropertyInterpolators

UIToolkitHandler=org.pushingpixels.trident.swt.SWTToolkitHandler
PropertyInterpolatorSource=org.pushingpixels.trident.swt.SWTPropertyInterpolators

UIToolkitHandler=org.pushingpixels.trident.android.AndroidToolkitHandler
PropertyInterpolatorSource=org.pushingpixels.trident.android.AndroidPropertyInterpolators

PropertyInterpolatorSource=org.pushingpixels.trident.interpolator.CorePropertyInterpolators

这应该解决它。
