未找到Gradle循环模块/在Java 9+中找不到或加载主类错误

Question

我正在通过gradle运行JavaFX 11（TornadoFX 2.0.0-RC1）应用程序，但是每次我使用run任务时，都会收到“找不到模块”或“找不到或加载主类”的信息。错误。

当我在构建之前运行干净时，它可以正常工作，但是在随后的构建中，我再次得到错误，直到我再次运行干净为止。必须在每次构建之前运行干净，这非常耗时，因此我希望有一种解决方案可以正确消除错误。

控制台输出：

14:34:30: Executing task 'run'...

Answer 1

似乎未应用module-info.class，这可能导致缺乏定义，mainClassName是什么。进行此模块构建可能是进行项目构建的前提。

mainClassName = "STTSim.TornadoFX/com.genguava.sttsim.app.SimApp"可能无效。
