Building a tag library for Freemarker, JSP or Velocity

  Once you have {{{./taglib.html}created a generic tag library}},
  Autotag will automatically generate the corresponding library
  for Freemarker, JSP, or Velocity. You just create a maven project 
  and include in <<<pom.xml>>>:
  
  * The appropriate implementation of tiles-request as a dependency. 
  For instance to build a JSP taglib:

-----------------
<dependency>
  <groupId>org.apache.tiles</groupId>
  <artifactId>tiles-request-jsp</artifactId>
  <version>1.0</version>
</dependency>
-----------------
  
  * Your generic tag library as a dependency. For instance:

-----------------
<dependency>
  <groupId>org.example</groupId>
  <artifactId>my-taglib</artifactId>
  <version>1.0-SNAPSHOT</version>
</dependency>
-----------------
  
  * The appropriate configuration of maven-autotag-plugin. For instance:
  
-----------------
<plugin>
  <groupId>org.apache.tiles.autotag.plugin</groupId>
  <artifactId>maven-autotag-plugin</artifactId>
  <version>1.0</version>
  <executions>
    <execution>
      <goals>
        <goal>generate-jsp</goal>
      </goals>
      <configuration>
        <packageName>org.example.mytaglib.jsp</packageName>
        <jspRuntime>org.apache.tiles.request.jsp.autotag.JspAutotagRuntime</jspRuntime>
        <taglibURI>http://example.org/mytaglib</taglibURI>
      </configuration> 
    </execution>
  </executions>
</plugin>
-----------------

  No further code is required.

Plugin goals

  one or several of the following goals may be used:

  [generate-jsp] generates the files required for a JSP tag library. It can then be included
  in a JSP using the configured taglibURI.
  
  [generate-freemarker] generates the files required for freemarker user-defined directives.
  The directives can then be made available to freemarker by adding an instance of the 
  generated class <<<...FMModelRepository>>> to the freemarker template model.
  
  [generate-velocity] generates the files required for velocity user directives. The directives
  can be made available to Velocity by setting the <<<userdirective>>> property, either manually
  or by using the generated file <<<META-INF/velocity.properties>>>.
  
Plugin configuration

  [packageName] the destination package for the generated classes.
  
  [freemarkerRuntime] the runtime implementation of TilesRequest to use for freemarker, for 
  instance <<<org.apache.tiles.request.freemarker.autotag.FreemarkerAutotagRuntime>>>.
  
  [jspRuntime] the runtime implementation of TilesRequest to use for JSP, for 
  instance <<<org.apache.tiles.request.jsp.autotag.JSPAutotagRuntime>>>.
  
  [velocityRuntime] the runtime implementation of TilesRequest to use for velocity, for 
  instance <<<org.apache.tiles.request.velocity.autotag.VelocityAutotagRuntime>>>.
  
  [taglibURI] the URI to use for the JSP taglib.
