Question

我有一个使用Nutiteq地图的midlet，我在Netbeans中开发了它。我将库jar添加到项目中。一切正常。问题是当我混淆时，我得到了这个：

  You should check if you need to specify additional program jars.
Warning: there were 12 unresolved references to classes or interfaces.
     You may need to specify additional library jars (using '-libraryjars'),
     or perhaps the '-dontskipnonpubliclibraryclasses' option.
Error: Please correct the above warnings first.
Note: there were 6 unresolved dynamic references to classes or interfaces.

我使用了lwuit库但是在我包含地图库之前我没有任何问题。

我做了这个页面所说的内容：http://www.nutiteq.com/j2me-maps-forum

现在我明白了：

重复类通常是无害的，但它们表明您的配置指定-libraryjars选项，其中包含两次相同类的jar。删除那些重复项会更干净。否则，您可以指定-dontnote来禁止这些注释。

意外错误是ProGuard中的错误。您应该确保使用的是最新版本（目前为4.8或4.9 beta）。如果问题仍然存在，您应该在ProGuard website上报告或邮寄给我，并通过一个允许我重现问题的小项目。您可以通过使用-dontoptimize关闭优化来解决它。
