GWT Maven使用位置註釋生成

我試圖將我的GWT應用程序轉換爲使用maven構建。我的第一個問題是，編譯器似乎不喜歡我的PlaceHistoryMapper中的「@WithTokenizers」 - 至少這是我認爲失敗的原因，如果我將它們評論出來，應用程序將編譯。我是否需要在我的pom中添加一些額外的配置才能使其工作？它在eclipse中編譯得很好，或者如果我在eclipse已經編譯了GWT源代碼之後嘗試構建maven的話。GWT Maven使用位置註釋生成

這裏是例外，我得到：

這裏是我的AdminPlaceHistoryMapper接口

// this annotation not working in mvn for some reason 
@WithTokenizers({ 
    UserDetailsPlace.Tokenizer.class, 
    UserPermissionsPlace.Tokenizer.class, 
    CompanyDetailsPlace.Tokenizer.class, 
}) 

public interface AdminPlaceHistoryMapper extends PlaceHistoryMapper { 
}

請將您'AdminPlaceHistoryMapper.java'文件。 – 2012-03-01 20:13:06

您是否正在編譯1.5版本的JDK？（請參閱http://twit88.com/blog/2008/03/09/maven-compile-your-application-to-be-14-15-or-16-compatible/） – 2012-03-01 21:01:58

事實證明，這是一個簡單的語法問題Eclipse編譯器忽略，但行家GWT編譯器標記。

From the "gwt-maven-plugin Users" Google Group

這似乎很明顯對我來說，它甚至給你的行號...

總之，在你標記生成器列表的末尾，你不能合法擁有一個逗號。這是一個語法錯誤。你的Eclipse編譯器容忍它，但大多數其他編譯器不會。

作爲旁註：如果您有數組聲明，則以逗號結尾是合法的。我認爲這是出於同質性... – helios 2012-03-06 13:36:16
