[SOLVED] ANTLRWorks undefined import error

ANTLRWorks undefined import error

I have ANTLRWorks 1.5.2. I need to resolve Decision can match input using multiple alternative warnings in my one grammar file which imports another file.

parser grammar PL;

import SQL;

I need to bring both of the files in antlr works. But Antlr Works throws undefined import error. How can I have both the files in ANTLR Works at the same time? The error has been generated by adding a rule in PL and it conflicts with the rule in SQL. These are very large grammar files and visualization can help to solve the problem.

Solution

ANTLRWorks actually imports the import grammar at runtime if import grammar is placed in the same folder. If grammar is placed at C:\test and import grammar is also placed at C:\test then ANTLRWorks reads the file from. When I generated the code it throws warnings in the imported grammar.
