title: Is there any generic Maven code generator?
body: <p>I am currently working on a project, that makes intense usage of code generation for various purposes. One generator generates SQL scripts from jpa entities. Another generates DTOs from pojos, another generates the JPA2.0 meta model, jet another generates some xml and schema files based on Java classes ... each generator works completely different needs to be configured differently.</p>
  
  <p>My question now is ... is there any generic maven code generator plugin out there with the following attributes:
  - Creates a pojo model of a Java class (Names, Properties, Annotation, Methods ...)
  - Uses templates for defining the output that uses the pojo model to generate any output.
  - Allows me to specify multiple templates for one class
  - Allows me to generate code and resources
  - Allows me to generate a base class to target/generated-sources and a dummy implementation to src/main/java which simply extends the base class (If the dummy class in src/main/java exists, nothing happens, if it doesn't it generates such a dummy class. This code is checked in to the SCM and allows extending the generated classes manually)</p>
  
  <p>I am using the Flexmojos GraniteDS plugin for generating my ActionScript model code, but it's pretty specialized for that particular purpose. </p>
  
  <p>I think such a generic generator would make things a lot easier.</p>
