@XmlRootElement not added to corresponding Java Class

Hi.
I am using Java 17 and Jakarta Xml Binding 3.0 for code generation from XML Schema.

The jaxb task results with the following error:

A possible solution without annotation plugin:

sourceSets {

test.java.srcDirs = ['src/test/java']
test.resources.srcDirs = ['src/test/resources']
}
