我已经从 Grails 2.2.4 切换到 Grails 2.4.3，我的 IntelliJ IDEA 13.1.4 IDE 遇到了严重问题。

在创建一个干净的 Grails 2.4.3 项目并添加一个干净的 Controller 类后，我通过 IntelliJ IDEA 中的“run-app”启动该项目。之后，我更改了 Controller 中的某些内容，并出现以下异常:

2014-09-29 18:45:41,801 [Thread-11] ERROR plugins.AbstractGrailsPluginManager  - Plugin

grails.project.fork = [

    //compile ":coffee-asset-pipeline:1.8.0"
    //compile ":handlebars-asset-pipeline:1.3.0.3"
}
}

我做了一些研究，发现我必须禁用 fork 模式，因为 IDEA 有问题。因此，我使用 grails.project.fork = false 选项在 BuildConfig.groovy 中禁用了此功能。

由于以下异常，现在我无法通过“run-app”启动应用程序:
