Java Question BA cannot be resolved to a type

@BA.ShortName
BA cannot be resolved to a type

Greetings, how could this error be solved, reinstall eclipse and it appears to me ... I have reviewed all the addresses of the external libraries and nothing ...
Thank you

You need to add a reference to jCore.jar

Greetings, incorporate jcore.jar into my project and delete core.jar

but in both cases:

this worked :import anywheresoftware.b4a.*;
and
this does not: import anywheresoftware.b4a.BA.ShortName;

it will be an error or it is ok (import anywheresoftware.b4a.*

On the other hand,
I can change this reference automatically, in eclipse,
the theme is that there are many classes of this project with the same problem in the reference "BA.ShortName",

Thank you

This is ok.
