The goal of the Java Generation plug-in is to allow Java code generation from a Java model. Such a generation will fulfill some of the requirements for Legacy refactoring & migration.

Description

JavaM2T.PNG

This plug-in proposes Acceleo MTL modules for generating Java files conforming to Java models. Templates are contained in two modules :

  • Structures modules : top level templates for generating classes/method/field declarations
  • Statements modules

Java models are obtained with Java Discoverer component.

Considering a Java legacy, a minimal migration/refactoring chain will involve :

  • A Java model discovery step
  • A m2m transformation step
  • A Java generation code step with the current component

Requirements

To use the plug-in you need:

  • JDK 1.5 or above
  • a version of Eclipse 3.5 or above with the following set of plug-ins installed

Install

All of the source code is stored in a public source repository, which you can access at:

https://dev.eclipse.org/svnroot/modeling/org.eclipse.mdt.modisco/main/trunk/org.eclipse.gmt.modisco.java.generation/


The bundle is also available from the MoDisco update site (only nightly update site at the moment).

User manual

A prerequisite is a Java model. Please refer to Java Discoverer user manual.

To launch Java generation :

  • Create an Accelo launch configuration pointing to Generate_JavaStructures java class, and specify the input model and target folder (require a checkout or import of the org.eclipse.gmt.modisco.java.generation into the workspace).

Or

  • Add org.eclipse.gmt.modisco.java.generation in your plugin dependencies and use the Generate_JavaStructures main method with input model and target folder as parameters.
