Google Pub/Sub Connector 1.0 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 access the connector from your app by adding reference statements to both your XML Mule flow and the Apache Maven pom.xml file.

  • If you add the connector in Studio, Studio automatically populates the XML code with the connector’s namespace and schema location and it also adds a dependency to the pom.xml file.

Add a Namespace for the Connector

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

http://www.mulesoft.org/schema/mule/google-pubsub
http://www.mulesoft.org/schema/mule/google-pubsub/current/mule-google-pubsub.xsd

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

<mule xmlns:ee="http://www.mulesoft.org/schema/mule/ee/core"
    xmlns:http="http://www.mulesoft.org/schema/mule/http"
	xmlns:google-pubsub="http://www.mulesoft.org/schema/mule/google-pubsub"
	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/google-pubsub
    http://www.mulesoft.org/schema/mule/google-pubsub/current/mule-google-pubsub.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">

Add a POM File Dependency

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

<dependency>
  <groupId>com.mulesoft.connectors</groupId>
  <artifactId>mule4-google-pubsub-connector</artifactId>
  <version>x.x.x</version>
  <classifier>mule-plugin</classifier>
</dependency>

Replace x.x.x with the version that corresponds to the connector you are using.

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

  1. Go to Anypoint Exchange.

  2. In Exchange, click Login and supply your Anypoint Platform username and password.

  3. In Exchange, search for google-pubsub.

  4. Select the connector.

  5. Click Dependency Snippets near the upper right of the screen.
