Testing with Java 12 and Gradle does not work

问题

我正在尝试使用 testfx、junit 和 powermock 来为我的 JavaFX 应用程序编写一些测试。当我从我的 IntelliJ IDEA IDE 中运行这些测试时，它们可以正常工作。但是，当我通过 Gradle 脚本的 'test' 任务运行它们时，我遇到了以下异常：

无法转换名称为 core.ui.TestBrowseDirUI 的类。原因：core.ui.TestBrowseDirUI
java.lang.IllegalStateException: 无法转换名称为 core.ui.TestBrowseDirUI 的类。原因：core.ui.TestBrowseDirUI
	...

核心的问题是 core.ui.TestBrowseDirUI 与被测试的类位于相同的包中（分割包）。从命令行中我可以看到，Gradle 已经应用了 --patch-module 以及所有需要的命令行选项。

The core.ui.TestBrowseDirUI is in the same package (split package) as the class under test. From the command line I saw, that gradle already applies --patch-module and all needed command line options.

已解决问题！

我将项目重新配置为多模块 Gradle 项目，其中一个模块是测试模块，另一个是应用模块。一旦我建立了这个结构，一切都开始正常工作起来。

英文:

Solved the problem!

I reconfigured my project to a multi-module gradle project where one module is the test module and the other is the app module. Once I had this structure in place everything started to work nicely.
