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

[Tilman Bender]

Hi Timotheus,

I from what I can see your snippet from pom.xml is lacking an  
execution element.
I have a working example here (be careful, I use the SNAPSHOT)

<plugin>
<groupId>org.antlr</groupId>
<artifactId>antlr3-maven-plugin</artifactId>
<version>3.1.4-SNAPSHOT</version>
<configuration>
<libDirectory>target/generated-sources/antlr3/de/hshn/se/akse/ss09/ 
parser/</libDirectory>
<!--<debug>true</debug>-->
<!-- print some fancy information about the grammars-->
<report>true</report>
<!-- generated parser code will log rule entry and exit points to  
stdout as an aid to debugging.-->
<trace>true</trace>
<!--   generate a dot graph of the NFA for each rule -->
<!-- <nfa>true</nfa> -->
<!-- generate a dot graph of the DFA for each decision in the grammar  
-->
<!-- <dfa>true</dfa> -->

                                 </configuration>
                                 <executions>
                                         <execution>
                                                 <id>antlr</id>
                                                 <phase>generate- 
sources</phase>
                                                 <goals>
                                                         <goal>antlr</ 
goal>
                                                 </goals>
                                         </execution>
                                 </executions>
                         </plugin>
