问题描述
这与我的第一个问题有关，但是自从我进一步了解以来，这个问题有了很大的改变。我无法在本机映像和Windows上找到有关此问题（看似简单的问题）的信息。
情况：IntelliJ运行我的应用程序，创建可执行的Jar也可以正常运行。
问题：我在本地图像的主FXML上遇到loadexception。这不是“位置未设置”错误，因此我认为这不是运行时类路径问题。
我的想法：由于Jar的问题是运行时类路径，因此本机映像是否仍然如此？如果是这样，如何在gluonClient {}路径中设置它？
解决方案：在@JoséPereda的帮助下，问题是一个不完整的ReflectionList。将stacktrace添加到catch块中后，我仍然需要添加“找不到的类”。我的困惑来自于事实，那就是jar和IntelliJ都不是问题。我有一些阅读要做。 ：）
