I'm trying to use antlr4 to generate a mysql parser in java.
I'm using g4 files in https://github.com/antlr/grammars-v4/tree/master/mysql and antlr-runtime 4.7.2. The generated java code MySqlParser.java has a size of 2526KB. When I put these files(MySqlParser.java, MySqlLexer.java, MySqlParserBaseListener.java, MySqlParserListener.java and my Main.java) in a simple java project within a single package, in my "main" method, idea just tells me "can't resolve symbol 'MySqlParser'". How can I fix this?

public static void main(String[] args) 
 String sql = "SELECT CUST_NAME FROM CUSTOMERS WHERE CUST_NAME LIKE 'Kash%'";

 MySqlLexer lexer = new MySqlLexer(CharStreams.fromString(sql));
 MySqlParser parser = new MySqlParser(new CommonTokenStream(lexer));
 ParseTree root = parser.dmlStatement();

 System.out.println(root.toStringTree(parser));

  Do you have any errors in MySqlParser class?
