Question

每当我使用JavaFX的FXMLLoader.load(URL)时，都会遇到这样的InvocationTargetException：

但是，我能够通过添加一堆--add-export VM-Flags来解决此问题，例如--add-exports=javafx.graphics/com.sun.javafx.reflect=ALL-UNNAMED

我添加了其中的20个，每个明显地解决了问题，每次添加其中的一个，又出现了一个，直到我达到大约10。GUI终于工作了，但是随着我的发展，重新运行会产生新的InvocationTargetExceptions。从那以后，我所做的每一个改变都发生了。大量添加确实可以解决问题，但是这对我来说非常不便和麻烦。另外，每次使用JavaFX时，都必须应用此方法。所以我的问题是：有没有更好的替代方法可以永久解决此问题？预先感谢，约翰

JavaFX InvocationTarget修复-有更好的替代方法吗？
