I'm having a problem; I need to split my grammar into a lexer grammar
and a parser grammar so I can specify a superClass option for the
lexer grammar.
My source files are
src/main/antlr/org/apache/tapestry5/internal/antlr/PropertyTokens.g
and PropertyExpression.g.
The plugin generates a PropertyTokens.tokens file as
target/generated-sources/antlr/org/apache/tapestry5/internal/antlr/PropertyTokens.token
So far, so good.
However, in my PropertyExpression.g file I've tried
options { tokenVocab=PropertyTokens; }
and
options {
tokenVocab="org/apache/tapestry5/internal/antlr/PropertyTokens";
}
and both fail. The first should work, but gets:
[INFO] [antlr3:antlr {execution: default}]
org/apache/tapestry5/internal/antlr/PropertyTokens.g
org/apache/tapestry5/internal/antlr/PropertyExpression.g
[ERROR] error(3): cannot find tokens file
/Users/Howard/work/tapestry5/tapestry-core/target/generated-sources/antlr/PropertyTokens.tokens
I think the plugin is not setting the -lib option correctly (see
Definitive ANTLR Reference, p. 110).
My workaround:
<plugin>
<groupId>org.antlr</groupId>
<artifactId>antlr3-maven-plugin</artifactId>
<version>3.1.1.2</version>
<executions>
<execution>
<goals>
<goal>antlr</goal>
</goals>
<configuration>
<!-- This is a hack so that the parser
grammar can locate the tokens file generated
by the lexer grammar. -->
<libDirectory>target/generated-sources/antlr/org/apache/tapestry5/internal/antlr</libDirectory>
</configuration>
</execution>
</executions>
</plugin>
This feels like a bug in either the Maven plugin or in ANTLR; it
should be able to find the .tokens file for a lexer grammar generated
from the same package folder. If I ended up having multiple grammars
in my project, I would have to put them all in a single package folder
for the build to work.
