Hey guys I'm using SXMaple v1.15.1 source. How do I dump the items, mobskills and quest? I have done compiling, sql execution and xmls are in the source. When I try to dump it gives me this:

ERRORcom.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could
not create connection to database server. Attempted reconnect 3 times. Giving u
p.
Dumping mobskills
java.lang.NullPointerException
0 skill.
Finished with errors in 0 minutes 4 seconds
Press any key to continue . . .

Should I edit the BAT files at the dist part? Or what? Help please thank you :D

It's saying you can't connect to your database.. make sure all your database properties are correct.
