創建一個與春天依賴關係的超級jar

Question

我想創建一個應用程序的jar，但運行到一個問題，因爲對spring框架的依賴。特別是，xml模式的命名空間是有問題的。你得到了臭名昭著的NamespaceHandler問題：

Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/c] 

爲了創建（簡單）尤伯杯罐子，Creating a bundle jar with ant，但如果你有春天的依賴由於彈簧罐子有文件，如spring.handlers這不起作用，spring.schemas和spring.tooling在他們的許多jar文件的META-INF目錄中。我相信命名空間的解析依賴於這些文件。

überjar似乎以某種方式包含所有必要的文件，但我猜測運行時只看到一個。

例如，我的尤伯杯罐子顯示一個罐子-tf（部分）

META-INF/spring.handlers 
META-INF/spring.schemas 
META-INF/spring.tooling 
META-INF/license.txt 
META-INF/notice.txt 
META-INF/spring.factories 
META-INF/spring.handlers 
META-INF/spring.schemas 
META-INF/spring.tooling 
META-INF/license.txt 
META-INF/notice.txt 
META-INF/license.txt 
META-INF/notice.txt 
META-INF/spring.handlers 
META-INF/spring.schemas 
META-INF/spring.tooling 
META-INF/license.txt 
META-INF/notice.txt 
META-INF/license.txt 

所以：問題..是有辦法創造尤伯杯罐子有內部捆綁春瓶？我需要合併META-INF文件嗎？任何人都有與蟻羣構建文件合併的經驗？

好吧..這是一個痛苦。
