[antlr-interest] Maven antlr integration ?

[Jim Idle]

As I said before, please use 3.2 not 3.3.

Thanks, Jim for the pointers.



I cleaned my maven cache.



Here are the errors on the console:



[INFO] --- antlr3-maven-plugin:3.3:antlr (default) @ core ---

[INFO] ANTLR: Processing source directory ../core/src/main/antlr3

ANTLR Parser Generator  Version 3.3 Nov 30, 2010 12:46:29

Java.g is indeed present as per the directory structure recommended in the
wiki.



../core$ ls src/main/antlr3/Java.g

src/main/antlr3/Java.g



The plugin fragment appears as below:  (using v 3.3 , the latest ).



   <plugin>

    <groupId>org.antlr</groupId>

    <artifactId>antlr3-maven-plugin</artifactId>

    <version>3.3</version>

    <executions>

        <execution>

            <goals>

                <goal>antlr</goal>

            </goals>

        </execution>

    </executions>

   </plugin>



What else could I be missing ?

I don't think that you are using the correct version of the documentation
and 3.1.3-1 is the wrong version of the maven plugin anyway.

Why not create your project using the archetype 3.2 and then just overlay
your own .g file. See:

http://www.antlr.org/wiki/display/ANTLR3/Building+ANTLR+Projects+with+Mave
n

Use version 3.2 as in the article as 3.3 seems not to work and I have not
had time to look at why just yet.

And also see the docs for the plugin at:

http://www.antlr.org/antlr3-maven-plugin/index.html

I think you are following docs for the ANTLR 2 plugin or something.
