问题描述
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，以下是重复显示（永远持续下去，陷入某种循环）。
I did a grails clean and afterwards when I run via grails run-app the app never starts and the following is repeatedly displayed (goes on forever, stuck in some kind of loop).
我在Windows XP上运行Grails 1.0.4，Java 1.6。

Grails以某种方式停留在无效配置中。任何想法如何恢复它？

推荐答案
Okay, I tracked it down. I had a single .java file that was completely commented out. This is 100% legal as far as Java is concerned but apparently Grails can't handle it. Grails must be assuming that any .java will have a corresponding .class files. Since the file contained no Java code, it produced no corresponding class file.
后续：这已在2.0-M2中修复，请参阅
Follow-up: This has been fixed in 2.0-M2, see GRAILS-3763
