[antlr-interest] Error: Declared package doesn't match expected package

[Sailesh Kandula]

Thanks,i explicitly created "annexextension.simpleCalc" and placed my
grammar file in that package,it worked. I thought ANTLR build creates a
package(if one doesn't exist) for the newly generated Lexer and Paser files
and puts them accordingly.
