Forked Grails虛擬機退出，出現錯誤grails 2.5.3

使用run-app時出現錯誤。這裏是我的路徑Forked Grails虛擬機退出，出現錯誤grails 2.5.3

➜ $ echo $GROOVY_HOME

當我使用run-app我得到一個錯誤

如果使用'--stacktrace'運行，您會得到有關鑼錯誤的信息嗎？ –

不幸的是，沒有。它不會產生任何堆棧跟蹤。輸出與上述相同。 – Anthony

我Grails 2.5.3得到這個：

Disconnected from the target VM, address: '127.0.0.1:19767', transport: 'socket' 
Error | 
Forked Grails VM exited with error 

Process finished with exit code 1

當我註釋掉的約束，並試圖挽救一本沒有作者的書

class Book { 
    static belongsTo = [authors: Author] 

    static constraints = { 
    // authors nullable: true 
    } 
}

我的解決方案是刪除static belongsTo = [authors: Author]
