In the grammar file...

@header {
package org.eatmoreveg.parser;
}
@lexer::header {
package org.eatmoreveg.parser;
}
|
...
In VegApp.java...
| Code Block |
|---|
package org.eatmoreveg;
import org.eatmoreveg.parser.VegLexer;
import org.eatmoreveg.parser.VegParser;
|
...
If you want to share a tokens file between grammars you will need to set the libDirectory variable to tell the plugin where to find it, as in this example...
