Java – GWT error: requestfactory validationtool must be run

Every time I start my application, even if it is not executed listempty@R_444_2419 @ES (), an error "requestfactory validation tool must run..." will also appear I already have the file requestfactory-apt-2.5 on annotation processing 0-rc1. jar.

Any ideas? Under my code thank you.

MyProject. java

private void listempty@R_444_2419@es() {
  @R_444_2419@Request @R_444_2419@Request = requestFactory.@R_444_2419@Request();
  @R_444_2419@Request.listAllEmpty().fire(new Receiver<List<@R_444_2419@Proxy>>() {
    public void onSuccess(List<@R_444_2419@Proxy> response) { // List all phantom @R_444_2419@es
      Window.alert("Successful");
    }
  });
}

@R_ 444_ 2419@Request.java

@Service(value=@R_444_2419@Dao.class,locator=DaoServiceLocator.class)
public interface @R_444_2419@Request extends RequestContext {
    Request<List<@R_444_2419@Proxy>> listAllEmpty();
}

@R_ 444_ 2419@Dao.java

public class @R_444_2419@Dao extends ObjectifyDao<@R_444_2419@>{
    public List<@R_444_2419@> listAllEmpty() {
        Objectify ofy = ObjectifyService.begin();
        Query<@R_444_2419@> q=ofy.query(@R_444_2419@.class).filter("title",null).filter("description",null);
        List<@R_444_2419@> results = q.list();
        return results;
    }
}

Solution

Starting with GWT 2.4, the requestfactory interface must be verified So, have you followed the instructions carefully? There you can find eclipse / IntelliJ and Maven / ant command line steps (also available in comments)

The output of the validation tool is a deobfusctorbuilder named "yourrequestfactoryname" Class, which is in the WEB-INF / classes directory with "yourrequestfactoryname" Class Therefore, by checking its existence, you will ensure that the validation tool is running (or delete it to ensure that it must be running)
