[antlr-interest] antlr3-maven-plugin not generating sources

[T Stotts]

I have created a Java project managed by Maven 2 that includes Antlr 3
grammar files. Following the instructions at:
    http://antlr.org/antlr3-maven-plugin/index.html
resulted in unexpected behavior.

(1) Antlr is never invoked during the generate-sources or compile
phases. The grammars are not processed.
   # mvn compile
or 
   # mvn package
do not result in the generation of Antlr source, nor the compilation
there of.


(2) Manually invoking the plugin with:
   # mvn mvn org.antlr:antlr3-maven-plugin:3.1.3-1:antlr
does cause the grammar files to be processed, and the generated sources
to be placed under:
   ./target/generated-sources/antlr3/
However, there is no phase/rule to then compile these generated
sources.

My pom.xml contains:

  <build>
    <plugins>
      ...
    
      <plugin>
        <groupId>org.antlr</groupId>
        <artifactId>antlr3-maven-plugin</artifactId>
        <version>3.1.3-1</version>        
        <executions>
          <execution>
            <configuration>
              <goals>
                <goal>antlr</goal>
              </goals>
              <verbose>true</verbose>
            </configuration>
          </execution>
        </executions>
      </plugin>

      ...
    </plugins>
  </build>
