Re: How to replace a Maven core component with a custom one?

[Francois-Xavier Bonnet]

Thanks Tamas,

I am using Maven 3.9.6 and building my extension with java 11
The project I am using to test the extension is built with Maven 3.9.6 and
java 11 and I can tell the extension is loaded because it also contains an
EventSpy that logs some stuff.
This is the code for my custom ProjectDepedencyResolver but it is not
loaded. What am I doing wrong?

import org.apache.maven.project.*;
import org.codehaus.plexus.component.annotations.Component;
import org.eclipse.sisu.Priority;

import javax.inject.Inject;
import javax.inject.Named;

@Named
@Component(role = ProjectDependenciesResolver.class)
@Priority(999)
public class CustomProjectDependencyResolver extends
DefaultProjectDependenciesResolver implements ProjectDependenciesResolver {

    @Inject
    public CustomProjectDependencyResolver() {
    }

    @Override
    public DependencyResolutionResult resolve(DependencyResolutionRequest
request) throws DependencyResolutionException {
        throw new RuntimeException(); // just crashing for now to check if
this class is properly injected
    }
}
