CQNGrammar Sources missing from master

[akumaburn]

import com.googlecode.cqengine.query.parser.cqn.grammar.CQNGrammarLexer;
import com.googlecode.cqengine.query.parser.cqn.grammar.CQNGrammarParser;

in com.googlecode.cqengine.query.parser.cqn.CQNParser seem to be missing,

Is there build instructions for this somewhere?

If you run mvn generate-sources or mvn compile it should generate those sources.
