java - Grails 未拾取已编译的 java .class 文件

Question

我正在将我的 grails 应用程序移动到新服务器，并且 run-app 失败(下面有详细的堆栈跟踪)。

grails 声称丢失的文件(“AutocompleteEntity”)是一个 java 源文件。它一定正在被编译，因为我在目标目录中看到 Autocomplete.class。

我尝试过 grails clean、rm'ing .grails 等各种组合，但没有成功。我很困惑!

Answer 1

我的 grails 2.3.11 应用程序 (GGTS 3.6.4) 在向枚举添加几个值后开始抛出异常 (run-app --stacktrace --verbose):

Error loading plugin manager: Type <className> not present
java.lang.TypeNotPresentException: Type <className> not present
...
Caused by: java.lang.ClassNotFoundException: <className> 
...
Error loading plugin manager: Type <className> not present

清理、删除 .grails 和目标文件夹后，我能够运行它十分之一。枚举位于 src/java 文件夹中。 .class 文件也在目标文件夹中。

在我将其移动到另一个包后，它开始工作。
