Answer 1

尝试升级到Grails的最新2.3.8版本。

Answer 2

我会尝试运行grails clean，然后重试。

Answer 3

Download springloaded-1.2.0.RELEASE.jar或最新。放入grails dir。使用以下命令运行grails

set GRAILS_OPTS=-server -Xmx768M -Xms64M -XX:PermSize=32m -XX:MaxPermSize=256m -Dfile.encoding=UTF-8 -javaagent:springloaded-1.2.0.RELEASE.jar -noverify -Dspringloaded.synchronize=true -Djdk.reflect.allowGetCallerClass=true  
grailsw -no-reloading run-app

注意：-no-reloading是禁用弹出的默认重载。重装会很好

grails -reloading run-app无法运行Grails，引发以下错误
