On qvto-cli

A command line interface (CLI) application to execute Eclipse Query/View/Transformation Operational (QVTo) model transformations without having Eclipse modeling IDE installed. The build procedure is fully automated using Maven, including resolution of Eclipse dependencies. The resulting artifact is a standalone jar which can be deployed and executed as-is. The aim is to provide a CLI component which can be glued to form composite applications and, thereby, make QVTo model transformations available to a broader range of (non-Java) applications.

qvto-cli consists of two sub-components:

• qvt-bundle: This is a Maven artifact which contains all QVTo standalone Eclipse plug-in (jar) dependencies. This is achieved by using Eclipse Tycho.
• qvto-app: This is a slim CLI app build to access Eclipse QVTo from the command line.

Prerequisites

• Maven 3.2.5
• Ant 1.9+
• Java 1.7

Build procedure

1. Clone this GIT repository and cd into it.
2. (cd qvt-bundle && mvn clean install)
3. (cd qvto-app && mvn clean compile package)

Note that Step 2 might require a considerable amount of time on the first run, because the corresponding Eclipse release (P2) repository is cloned and mirrored on your machine.

Usage

Usage: java -jar qvto-app-0.1-SNAPSHOT.jar [options] 
  Options:
  * -xform, --transformation
       QVTo transformation to be executed
  * -src
       Pairs of source metamodel and source model
       Default: []
    -tgt
       Pair of target metamodel and target model
       Default: []

Limitations

Beware that this project is work in progress. qvto-app is only a minimal viable software product to learn more about possible usage scenarios and meant for demonstration purposes. The CL interface is only exemplary and the app implementation rather bold. qvt-bundle represents only one approach to render Eclipse dependencies available in a Maven setup and some decisions might be revised in the future (using the Eclipse Jar-in-Jar class loader, bundling all Eclipse jars along with their unpacked content in the Maven artifact jar etc.).

As of this writing, qvto-cli was only tested against:

• Eclipse 4.4 Luna
• Eclipse QVTo 3.4.0
