I could include the controlsfx into my project in IntelliJ but I can't run the program.
I also already try the other solution: adding this into VM options

我可以将controlsfx包含到我的IntelliJ项目中，但我无法运行该程序。我也已经尝试了另一种解决方案：将其添加到VM选项中

--add-exports=javafx.base/com.sun.javafx.event=org.controlsfx.controls

When I run the program, it has run time error:

当我运行该程序时，它出现运行时错误：

I hope I could use the controls fx in my project.

It looks like org.controlsfx.controls is being put onto the class path instead of the module path by IntelliJ:

看起来像是IntelliJ将org.Controsfx.Controls放到了类路径而不是模块路径上：

class org.controlsfx.control.textfield.AutoCompletionBinding (in unnamed module @0x6bbb636e)

(The unnamed modules means the class path).

(未命名的模块表示类路径)。

IntelliJ puts dependencies on the class or module path depending on whether the project itself is modular. So, in order to have IJ put org.controlsfx.controls on the module path, you have to modularise the project by adding a module-info.java file.

IntelliJ根据项目本身是否是模块化的，将依赖项放在类或模块路径上。因此，为了让IJ将org.controlsfx.controls放在模块路径上，您必须通过添加module-info.java文件来模块化项目。

(see also: IntelliJ: Put some dependencies on the module path in non-modular application)

(另见：IntelliJ：在非模块化应用程序中的模块路径上放置一些依赖项)

If you don't want to modularise your project, alternatively you could try using:

如果您不想模块化您的项目，或者您可以尝试使用：

--add-exports=javafx.base/com.sun.javafx.event=All-UNNAMED

Which exports the package to the class path instead (unnamed module). However, this might not work if org.controlsfx.controls does not support being put on the class path.

它将包导出到类路径(未命名模块)。但是，如果org.Controsfx.Controls不支持放在类路径上，则这可能不起作用。
