javacc support

[ryan.campbell]

I'm adding javacc support to jbossbuild. I think the way to do this is to allow source code to act as input to source nodes:

<generatedsource id="jboss-ql-parser"
 javacc="org/jboss/ejb/plugins/cmp/ejbql/JBossQLParser.jjt"/>
 <generatedsource id="ejb-ql-parser"
 path="jboss-ql-parser"
 javacc="org/jboss/ejb/plugins/cmp/ejbql/EJBQLParser.jjt"/>

 <source id="main">
 <include input="jboss-ql-parser"/>
 <include input="ejb-ql-parser"/>

 <include input="commons"/>

So this would create output/gen-src/jboss-ql-parser which would then be included as a src dir by javac.

Thoughts?

I have implemented this, with some slight changes to the syntax (for future reference):

<generatedsource id="jboss-ql-parser"
 srcdir="main"
 javacc="org/jboss/ejb/plugins/cmp/ejbql/JBossQLParser.jjt"/>

 <generatedsource id="ejb-ql-parser"
 srcdir="main"
 path="jboss-ql-parser"
 javacc="org/jboss/ejb/plugins/cmp/ejbql/EJBQLParser.jjt"/>

 <source id="main">
 <include input="jboss-ql-parser"/>

 <include input="commons"/>

In this case, the ejb-ql-parser needs to output to the jboss-ql-parser output directory (output/gen-src/jboss-ql-parser), so you only need to include one as input to the source node. The source files from the generated code will be included in the javac call for the main source.
