运行 Grails 应用程序时出现错误。

我的应用程序在 Grails 2.1.4 中工作。

我在用

Groovy 2.1.*
Java 1.7
Tomcat 7.0.37

我将我的应用程序从 Grails 2.1.4 升级到了 2.3.0.M1。在我收到这样的错误后：

我在如何将 Grails 2.1 迁移到 Grails 2.3 应用程序中回答了类似的问题。作为总结，将Config.groovy&BuildConfig.groovy与新 Grails 2.3 应用程序的默认版本进行比较。确保您的依赖项是 inBuildConfig.groovy而不是application.propertiesTomcat 、 Hibernate和Scaffolding插件是正确的版本并且具有正确的范围（为Tomcat 插件构建，为Hibernate构建运行时）。

我在错误日志中看到了这一行：

Error Exception in thread "Thread-7" 
| Error java.lang.RuntimeException: Forked Grails VM exited with error

尝试注释掉BuildConfig.groovy的grails.project.fork部分

我有同样的错误，问题是代码中文件名和类名之间的字母大小写不同。确保您的类名和文件名完全匹配。

例如，我的文件名是 OAuthCallBackController.groovy，类名是 OauthCallBackController（注意小写“a”）
