Java 如何修复使用jfoenix触发的错误？

我将JFoenix添加到eclipse和SceneBuilder中。 它在SceneBuilder中工作，但在完成项目时会导致ClassNotFoundException

scenebuilder

能够找到

jphoenix

库，但是您的项目/您编写的java代码找不到jphoenix库。这就是为什么您会得到

ClassNotFoundException

。所以要解决这个问题，必须在项目中导入jar文件。我自己不使用eclipse，所以我自己也不知道如何做到这一点。一个快速的谷歌揭示了这个答案：

根据这一点，

您可以通过右键单击项目在Eclipse中添加一个jar→ 构建路径→ 配置生成路径。在“库”选项卡下，单击“添加Jar”或“添加外部Jar”并提供Jar。

也许这会有帮助。一旦导入，您的项目应该正确编译。祝你好运。

在我的例子中，jar也是在eclipse上导入的！！这就是问题所在
