在 grails clean 之后我无法运行应用程序

Question

我做了一个grails clean，然后当我通过grails run-app 运行时，应用程序永远不会启动，并且重复显示以下内容（永远持续，陷入某种循环）。

我在 Windows XP 上运行 Grails 1.0.4、Java 1.6。

Grails 不知何故陷入了无效配置。知道如何恢复吗？

Answer 1

好的，我找到了。我有一个完全被注释掉的 .java 文件。就 Java 而言，这是 100% 合法的，但显然 Grails 无法处理。 Grails 必须假设任何 .java 都会有相应的 .class 文件。由于该文件不包含 Java 代码，因此它没有生成相应的类文件。

跟进：这已在 2.0-M2 中修复，见GRAILS-3763
