我试图实施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）但是当我尝试使用JMenuBar中的菜单时，我会在下面得到例外。
我发现了非常类似的问题，但肯定是不同的 - Flamingo ribbon: Java.lang.IllegalArgumentException: No interpolator found for java.lang.Float:java.lang.Float。

有什么想法吗？
答案 0 :(得分：0)
经过一段时间后，我找到了解决方法。错误
java.lang.IllegalArgumentException：找不到java.lang.Float的插补器：java.lang.Float
与TimelinePropertyBuilder类中的代码无关。 它错过了相应顶级库trident-plugin.properties中的META-INF文件。确切地说定义了Interpolator类源。
所以不是寻找它，而是需要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。
