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.
- Maven 3.2.5
- Ant 1.9+
- Java 1.7
- Clone this GIT repository and
cdinto it. (cd qvt-bundle && mvn clean install)(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: 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: []
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
