Setup

In your application’s top level pom.xml, add a dependency for this module’s own bill of materials (BOM):

pom.xml

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.apache.causeway.extensions</groupId>
            <artifactId>causeway-extensions-cors</artifactId>
            <scope>import</scope>
            <type>pom</type>
            <version>3.1.0</version>
        </dependency>
    </dependencies>
</dependencyManagement>

Dependencies / Imports

In the webapp module of your application, add the following dependency:

pom.xml

<dependency>
    <groupId>org.apache.causeway.extensions</groupId>

</dependency>

In your application’s App Manifest, import the extension’s implementation module:

AppManifest.java

@Configuration
@Import({

})
public class AppManifest {
}
