JAR export finished with warnings. See details for additional information.封装时的提示

JAR export finished with warnings. See details for additional information.打包时的提示,求高人指点!!!!!!!!!
我做的东西在eclipse下运行一切正常,就是有几个警告,但是不影响什么,可是在打jar包时出现了以下信息,但是jar文件就是不能正常运行?虽然是警告不是错误!
提示信息是:
JAR   export   finished   with   warnings.   See   details   for   additional   information.
    Exported   with   compile   warnings:   /StudentManage/Interface/Interface/ScoreInputFace.java
    Exported   with   compile   warnings:   /StudentManage/Interface/Interface/MainWindow.java
    Exported   with   compile   warnings:   /StudentManage/Interface/Interface/Loading.java
    Exported   with   compile   warnings:   /StudentManage/Interface/Interface/Administrator.java
    Exported   with   compile   warnings:   /StudentManage/Interface/Interface/InputFace.java
    Exported   with   compile   warnings:   /StudentManage/Interface/MyTable/MyTable.java
    Exported   with   compile   warnings:   /StudentManage/DBcontrol/DBcontrol/DBcontrol.java
求高人指点!!!!!!万分感谢,或与我qq联系:287786838

这个只是说打入包中的java文件，在编译的时候有警告，并不影响使用。如果要让打包过程没有这个提示，需要修改这些文件。
/StudentManage/Interface/Interface/ScoreInputFace.java
/StudentManage/Interface/Interface/MainWindow.java
/StudentManage/Interface/Interface/Loading.java
/StudentManage/Interface/Interface/Administrator.java
/StudentManage/Interface/Interface/InputFace.java
/StudentManage/Interface/MyTable/MyTable.java
/StudentManage/DBcontrol/DBcontrol/DBcontrol.java
