錯誤貝寶插件2.0.0.RC3

Question

我使用的Grails 2.0.0.rc3，當我安裝插件的PayPal我有這樣的錯誤：

Error Compilation error: startup failed: 
/Users/sartre/.grails/2.0.0.M1/projects/testapp/plugins/paypal-0.6.4/grails-app/controllers/org/grails/paypal/PaypalController.groovy: -1: The return type of java.lang.Object notify() in org.grails.paypal.PaypalController is incompatible with void notify() in java.lang.Object 
. At [-1:-1] @ line -1, column -1. 
1 error 

我怎樣才能解決這個問題？

非常感謝任何想法

Answer 1

grails 2.0中的不兼容性變化！它似乎與grails 2.0的一個小改動有關。

It is now possible to define controller actions as methods instead of using closures as in previous versions of Grails. (from official doc : http://grails.org/doc/2.0.x/guide/introduction.html#webFeatures)

它的行爲象封閉通知PaypalController覆蓋Object.notify方法。 如果您在notifyPaypal中重命名notify，它應該可以工作。
