Scripting Module - XML and Maven Support - Mule 4

Although you can manually code a Mule app in XML, it is more efficient to use Anypoint Studio.

If you manually code a Mule runtime engine (Mule) app in XML, either from the Anypoint Studio XML editor or from a text editor, you can get access to the connector in your app by adding reference statements to both your XML Mule flow and the Apache Maven pom.xml file.

When you install the connector in Studio, Studio automatically populates the XML code with the connector’s namespace and schema location. It also adds a dependency to the pom.xml file.

Add a Namespace for the Module

Paste the following code inside the <mule> tag of the header of your configuration XML:

http://www.mulesoft.org/schema/mule/scripting-module
http://www.mulesoft.org/schema/mule/scripting-module/current/mule-scripting-module.xsd

This example shows how the namespace statements are placed in the <mule> XML block:

<mule xmlns:scripting="http://www.mulesoft.org/schema/mule/scripting"
	xmlns:ee="http://www.mulesoft.org/schema/mule/ee/core"
	xmlns:http="http://www.mulesoft.org/schema/mule/http"
	xmlns:file="http://www.mulesoft.org/schema/mule/file"
	xmlns="http://www.mulesoft.org/schema/mule/core"
	xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.mulesoft.org/schema/mule/core
	http://www.mulesoft.org/schema/mule/core/current/mule.xsd
	http://www.mulesoft.org/schema/mule/file
	http://www.mulesoft.org/schema/mule/file/current/mule-file.xsd
	http://www.mulesoft.org/schema/mule/http
	http://www.mulesoft.org/schema/mule/http/current/mule-http.xsd
	http://www.mulesoft.org/schema/mule/ee/core
	http://www.mulesoft.org/schema/mule/ee/core/current/mule-ee.xsd
    http://www.mulesoft.org/schema/mule/scripting
    http://www.mulesoft.org/schema/mule/scripting/current/mule-scripting.xsd">

Add a POM File Dependency

The Apache Maven pom.xml file generated by Anypoint Studio contains dependencies for a Mule app. If you code a Mule app manually, include this XML snippet in your pom.xml file to enable access to this connector:

<dependency>
    <groupId>org.mule.modules</groupId>
    <artifactId>mule-scripting-module</artifactId>
    <version>2.0.0</version>
    <classifier>mule-plugin</classifier>
</dependency>

To obtain the most up-to-date pom.xml file information:

Go to Anypoint Exchange.
In Exchange, click Login and supply your Anypoint Platform username and password.
In Exchange, search for Scripting Module.
Select the module.
Click Dependency Snippets near the upper right of the screen.

Notice that since Scripting Module does not provide execution engines, you have to provide an execution engine yourself. For example, review the following list of engines provided by the previous version of Scripting Module:

Groovy:

Scripting module supports version 2.4.x for Groovy. Anypoint Studio recommends using version 2.4.21.

    <dependency>
        <groupId>org.codehaus.groovy</groupId>
        <artifactId>groovy-all</artifactId>
        <version>2.4.21</version>
        <classifier>indy</classifier>
    </dependency>

Python:

    <dependency>
        <groupId>org.python</groupId>
        <artifactId>jython-standalone</artifactId>
        <version>2.7.2</version>
    </dependency>

Ruby:

    <dependency>
        <groupId>org.jruby</groupId>
        <artifactId>jruby-core</artifactId>
        <version>9.2.11.1</version>
    </dependency>
    <dependency>
        <groupId>org.jruby</groupId>
        <artifactId>jruby-stdlib</artifactId>
        <version>9.2.11.1</version>
    </dependency>
