How do I solve this spec loader error in apache isis - isis

Question

I am using the income platform as a test platform. I have added an entity in a separate module Provider. Provider has a reference to itself via a parent property. I want to ensure that I can use autocomplete or be able to select a provider from a list when filling the parent field.
Whenever I add the Autocomplete option in the #DomainObject annotation and reference the ProviderRepository, I am getting a build error as below.
[DEBUG] Meta model invalid
org.apache.isis.core.metamodel.specloader.validator.MetaModelInvalidException: 1: #DomainObject annotation on domainapp.modules.provider.dom.Provider specifies unknown repository 'd

public List<Provider> autoComplete(final String description) {
return findByName(description);

//endregion
#javax.inject.Inject

}
I have been unable to figure out what the issue is.

Answer 1

What's happening here is that you are running the Isis Maven plugin, and it is using an AppManifest (defined in the pom.xml) that - I am guessing - doesn't reference your new module that contains these classes.
I'm guessing you probably cloned the module-simple for your new module. In that case you can fix things by either:
adding in the new module to the manifest referenced by the plugin in your new module (not that of module-simple)
using -Dskip.isis-validate on the mvn command line
remove the plugin by removing the mavenmixin-isis-validate
