如何解決「javadoc：警告 - 爲a.b.c包找到多個包註釋源」？

Question

我很過時，但我剛剛升級我的項目使用JDK 1.5的JDK 1.4，現在運行mvn javadoc:javadoc的時候，我遇到以下的javadoc警告：

[WARNING] javadoc: warning - Multiple sources of package comments found for package "com.a" 
[WARNING] javadoc: warning - Multiple sources of package comments found for package "com.b" 
[WARNING] javadoc: warning - Multiple sources of package comments found for package "com.c" 
[WARNING] javadoc: warning - Multiple sources of package comments found for package "com.a" 

什麼我需要做的修復它們？有什麼東西從JDK 1.4改爲1.5？

謝謝！

這個thread in the Oracle forums討論這個。

也許您需要新版本的maven？
