Running Epsilon's Ant Tasks from Command Line

This example project shows how to download, configure and run Epsilon's Ant tasks from the command line using Ant, Maven and Gradle. To debug Epsilon scripts running from these tasks, read these instructions.

To run the examples below, you only need to have Ant, Maven or Gradle installed in your system.

Ant

When you run the ant command in the root directory of the project, the following will happen:

• The build file (build.xml) will download Apache Ivy in a temporary directory
• Ivy will fetch the required Epsilon jars (also in a temporary directory) from Maven Central/Sonatype
• The build file will set up Epsilon's Ant tasks
• The following part of the build file will be executed, which will load an EMF-based model and then run an EOL program against it

<epsilon.emf.loadModel name="Library" modelfile="library.model" 
    metamodelfile="library.ecore"/>

<epsilon.eol>
    for (writer in Writer.all) {
        (writer.name + " wrote " + writer.books.title.concat(", ")).println();
    }
    <model ref="Library"/>
</epsilon.eol>

If everything goes well, the last few lines of the output of the ant command should look like this:

run-epsilon:
[epsilon.eol] Agatha Christie wrote Endless Night

BUILD SUCCESSFUL

The complete source code is below and in Epsilon's Git repo.

Maven

Since Maven can run Ant tasks, Epsilon Ant tasks can also be executed from a Maven build (mvn clean package) as shown below.

Gradle

Since Gradle can also run Ant tasks, Epsilon Ant tasks can also be executed from a Gradle build (gradle run) as shown below.

build.gradle

configurations {
    epsilon
}

repositories {
    mavenCentral()
}

dependencies {
    epsilon 'org.eclipse.epsilon:org.eclipse.epsilon.workflow:2.5.0'
    epsilon 'org.eclipse.epsilon:org.eclipse.epsilon.workflow.emf:2.5.0'
    epsilon 'org.eclipse.epsilon:org.eclipse.epsilon.eunit.cmp.emf:2.5.0'
}

task setupEpsilonTasks {
    // Set up the core Epsilon tasks
    ant.taskdef(resource: 'org/eclipse/epsilon/workflow/tasks/tasks.xml', 
        classpath: configurations.epsilon.asPath, loaderref: 'epsilon')
    // Set up the Epsilon EMF tasks
    ant.taskdef(resource: 'org/eclipse/epsilon/workflow/tasks/emf/tasks.xml', 
        classpath: configurations.epsilon.asPath, loaderref: 'epsilon')
    // Set logging level to info so that EOL's println() is not suppressed
    ant.lifecycleLogLevel = 'INFO'
}

task run {
    dependsOn tasks.setupEpsilonTasks
    // Load the library.model EMF model
    ant.'epsilon.emf.loadModel'(name: 'Library', 
        modelfile: 'library.model', metamodelfile: 'library.ecore')

    // Run library.eol against it
    ant.'epsilon.eol'(src: 'library.eol'){ model(ref: 'Library') }

    // Run library.eunit
    ant.'epsilon.eunit'(src: 'library.eunit'){
        modelTasks() {
            ant.'epsilon.emf.loadModel'(name: 'A', metamodelfile: 'library.ecore',
                read: 'false', store: 'false', modelfile: 'dummyA.model')
            ant.'epsilon.emf.loadModel'(name: 'B', metamodelfile: 'library.ecore',
                read: 'false', store: 'false', modelfile: 'dummyB.model')
        }
        comparators() {
            comparator(classname:
                'org.eclipse.epsilon.eunit.cmp.emf.EMFModelComparator')
        }
    }
}

Flexmi and Emfatic

You can also use Flexmi instead of XMI (library.flexmi instead of library.model) for the model, and Emfatic instead of Ecore (library.emf instead of library.ecore) by adding the following dependency to your ANT/Maven/Gradle build.

Ivy/ANTMavenGradle

<dependency org="org.eclipse.emfatic" name="org.eclipse.emfatic.core" rev="1.1.0" conf="binaries->default"/>

<dependency>
    <groupId>org.eclipse.emfatic</groupId>
    <artifactId>org.eclipse.emfatic.core</artifactId>
    <version>1.1.0</version>
</dependency>

epsilon 'org.eclipse.emfatic:org.eclipse.emfatic.core:1.1.0'

A complete Gradle example that uses library.flexmi instead of (the XMI-based) library.model, and library.emf instead of library.ecore is shown below.

build.gradlelibrary.eollibrary.flexmilibrary.emf

configurations {
    epsilon
}

repositories {
    mavenCentral()
}

dependencies {
    epsilon 'org.eclipse.epsilon:org.eclipse.epsilon.workflow:2.5.0'
    epsilon 'org.eclipse.epsilon:org.eclipse.epsilon.workflow.emf:2.5.0'
    epsilon 'org.eclipse.emfatic:org.eclipse.emfatic.core:1.1.0'
}

task setupEpsilonTasks {
    // Set up the core Epsilon tasks
    ant.taskdef(resource: 'org/eclipse/epsilon/workflow/tasks/tasks.xml', 
        classpath: configurations.epsilon.asPath, loaderref: 'epsilon')
    // Set up the Epsilon EMF tasks
    ant.taskdef(resource: 'org/eclipse/epsilon/workflow/tasks/emf/tasks.xml', 
        classpath: configurations.epsilon.asPath, loaderref: 'epsilon')
    // Set logging level to info so that EOL's println() is not suppressed
    ant.lifecycleLogLevel = 'INFO'
}

task run {
    dependsOn tasks.setupEpsilonTasks
    // Load the library.flexmi EMF model
    ant.'epsilon.emf.loadModel'(name: 'Library', 
        modelfile: '../library.flexmi', metamodelfile: '../library.emf')

    // Run library.eol against it
    ant.'epsilon.eol'(src: '../library.eol'){ model(ref: 'Library') }
}

for (writer in Writer.all) {
    (writer.name + " wrote " + writer.books.title.concat(", ")).println();
}

<?nsuri library?>
<library>
  <writer name="Agatha Christie"/>
  <book title="Endless Night" pages="224" author="Agatha Christie"/>
</library>

@namespace(uri="library", prefix="")
package library;

class Library {
    val Writer[*] writers;
    val Book[*] books;
}

class Writer {
    attr String name;
    ref Book[*]#author books;
}

class Book {
    attr String title;
    attr int pages = 100;
    attr BookCategory category;
    ref Writer[1]#books author;
}

enum BookCategory {
    Mystery = 0;
    ScienceFiction = 1;
    Biography = 2;
}

Excel

The example below demonstrates using the generic epsilon.loadModel task to run the same EOL program against an Excel spreadsheet.

build.gradlemapping.xml

configurations {
    epsilon
}

repositories {
    mavenCentral()
}

dependencies {
    epsilon 'org.eclipse.epsilon:org.eclipse.epsilon.workflow:2.5.0'
    epsilon 'org.eclipse.epsilon:org.eclipse.epsilon.emc.spreadsheets.excel:2.5.0'
}

task setupEpsilonTasks {
    // Set up the core Epsilon tasks
    ant.taskdef(resource: 'org/eclipse/epsilon/workflow/tasks/tasks.xml', 
        classpath: configurations.epsilon.asPath, loaderref: 'epsilon')
    // Set logging level to info so that EOL's println() is not suppressed
    ant.lifecycleLogLevel = 'INFO'
}

task run {
    dependsOn tasks.setupEpsilonTasks
    // Load the library.xlsx spreadsheet
    ant.'epsilon.loadModel'(name: 'Library', impl: 'org.eclipse.epsilon.emc.spreadsheets.excel.ExcelModel'){
        parameter(name: 'SPREADSHEET_FILE', file: 'library.xlsx')
        parameter(name: 'CONFIGURATION_FILE', file: 'mapping.xml')
    }

    // Run library.eol against it
    ant.'epsilon.eol'(src: '../library.eol'){ model(ref: 'Library') }
}

<spreadsheet>
  <worksheet name="Writer">
    <column name="name"/>
    <column name="books" many="true"/>
  </worksheet>
  <worksheet name="Book">
    <column name="id"/>
    <column name="title"/>    
    <column name="pages" datatype="integer"/>
  </worksheet>
  <reference source="Writer->books"
             target="Book->id"/>                    
</spreadsheet>

UML

Models conforming to the Eclipse UML2 metamodel can be queried as shown below.

build.gradleuml.eolmodel.uml

configurations {

repositories {
    maven {
        url "https://repo.eclipse.org/content/repositories/acceleo-releases/"

    // Set up the core Epsilon tasks
    ant.taskdef(resource: 'org/eclipse/epsilon/workflow/tasks/tasks.xml', 
        classpath: configurations.epsilon.asPath, loaderref: 'epsilon')

    // Set logging level to info so that EOL's println() is not suppressed
    ant.lifecycleLogLevel = 'INFO'
}

    ant.'epsilon.loadModel'(name: 'UML', impl: 'org.eclipse.epsilon.emc.uml.UmlModel'){
        parameter(name: 'modelFile', file: 'model.uml')
    }

    // Run library.eol against it
    ant.'epsilon.eol'(src: 'uml.eol'){ model(ref: 'UML') }
