XSD validation in your IDE

Annoyed by red attributes in your XMLs edited by your favourite IDE? There is an easy trick get rid of that and validate your XMLs against Magento 2 XSD schemas.

In your project root, run following command:

bin/magento dev:urn-catalog:generate .idea/misc.xml

This will generate misc.xml file in your .idea folder. If you open it you should see something like this:

<?xml version="1.0" encoding="UTF-8"?>
<project version="4">
  <component name="ProjectResources">
    <resource url="urn:magento:framework-message-queue:etc/consumer.xsd" location="$PROJECT_DIR$/vendor/magento/framework-message-queue/etc/consumer.xsd" />
    .
    .
    .
  </component>
</project>

Based on that your IDE (PHPStorm in our case) will validate your XMLs against Magento 2 XSD schemas.
