How to add a module programmatically in Wildfly?

Question

In Wildfly-CLI jboss-cli.sh it is possible to add a module like this

module add --name=org.postgres
           --resources=postgresql-42.2.5.jar
           --dependencies=javax.api,javax.transaction.api

This adds the file postgresql-42.2.5.jar and creates module.xml with the following structure in /modules/org/postgres/main :

<?xml version='1.0' encoding='UTF-8'?>
<module xmlns="urn:jboss:module:1.1" name="org.postgres">
    <resources>
        <resource-root path="postgresql-42.5.1.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
    </dependencies>
</module>

How can this be done programmatically with ModelControllerClient (available in org.wildfly.core:wildfly-controller-client:19.0.1.Final )?

ModelControllerClient client = ModelControllerClient.Factory.create(InetAddress.getByName("localhost"), 9990);

Answer 1

It cannot be done with the ModelControllerClient . The module command is a high level CLI command and not what is referred to as an operation.

You could launch a CLI process and send the command. The other option would be to copy the JAR and create the module.xml programmatically.
