ProGuard：找不到引用的类（到R.java）

Question

I have an Android app that references to a library Android project. That setup basically works fine (as debug release in Eclipse). However, when I try to export a signed release apk of the main app, with ProGuard enabled in project.properties, export fails.

Problem seems to be that ProGuard can't find the resource class R.java of the referenced library project, because all warnings complain about R$string, R$layout, etc. of that library project.

I am using Android's default proguard.cfg file.
Do I need any changes in that case?

Thanks in advance!

我确实必须在proguard.cfg文件中使用-libraryjars开关包括库项目源文件夹的路径。
