I am using the antlr task in ant to build a special-purpose compiler. I am fairly new to ant.
It appears to me that the antlr task does not (and perhaps cannot) understand dependencies that relate to imported and exported token vocabularies. For example, if I change a parser grammar in file p.g, then the related antlr task will generate P.java, PTokenTypes.java, and PTokenTypes.txt. The latter file is used by the lexer, contained in file l.g, to define its input token vocabulary. As far as I can tell, the antlr task that handles the lexer (i.e. with target 'l.g') does not know that a change to PTokenTypes.txt should force antlr to run on l.g. I spent a frustrating hour last night determining that the lexer and parser were using mismatching token vocabularies. Can anyone tell me how to set ant up to account for this?
