Simple configuration

 If your grammar files are organized into the default locations as described in the {{{../index.html}introduction}},
 then configuring the pom.xml file for your project is as simple as adding this to it

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

 When the mvn command is executed all grammar files under <<<src/main/antlr3>>>, except any
 import grammars under <<<src/main/antlr3/imports>>> will be analyzed and converted to
 java source code in the output directory <<<target/generated-sources/antlr3>>>.

 Your input files under <<<antlr3>>> should be stored in sub directories that
 reflect the package structure of your java parsers. If your grammar file parser.g contains:

+---
@header {
package org.jimi.themuss;
}
+---

 Then the .g file should be stored in: <<<src/main/antlr3/org/jimi/themuss/parser.g>>>. THis way
 the generated .java files will correctly reflect the package structure in which they will
 finally rest as classes.
