show error when compile lib that I wrapped for basic4android

Question

I wrapped a source github for b4a with Eclipse.

I added core.jar but when I compile the project in b4a it shows this error:

trouble processing "java/com/lsjwzh/widget/materialloadingprogressbar/CircleProgressBar$OvalShadow.class": Ill-advised or mistaken usage of a core class (java.* or javax.*) when not building a core library.

This is often due to inadvertently including a core library file in your application's project, when using an IDE (such as Eclipse). If you are sure you're not intentionally defining a core class, then this is the most likely explanation of what's going on.

However, you might actually be trying to define a class in a core namespace, the source of which you may have taken, for example, from a non-Android virtual machine project. This will most assuredly not work. At a minimum, it jeopradizes the compatibility of your app with future versions of the platform.

I changed package name from

java.com.lsjwzh.widget.materialloadingprogressbar

to

com.lsjwzh.widget.materialloadingprogressbar

Why show in error -

"java/com/lsjwzh/widget/materialloadingprogressbar/CircleProgressBar$OvalShadow.class"

?

I rebuilt the project in eclipse and compile with SimpleLibraryCompiler for b4a.
