Hi everybody,

We had a maven errai project with 1 module containing an ApplicationScoped bean named Keycloak, that was injected in other beans and everything used to work fine.

Now we have exported the Keycloak bean and other classes to a separate gwt module, to share it with the current main module and gwt modules we are going to add in the near future.

So at the moment we have 2 gwt modules (corresponding to  2 maven modules):

1. com.vivaldi.varco.common.Common with the following gwt.xml, that is a maven module with the same parent of the main module com.vivaldi.varco.manager.Manager

<module>
  <inherits name="org.jboss.errai.enterprise.All" />
  <inherits name="com.google.gwt.user.User"/>


  <inherits name="org.jboss.errai.validation.Validation" />
  <inherits name="org.hibernate.validator.HibernateValidator" />
  <inherits name="org.jboss.errai.jpa.JPA"/>


  <source path="keycloak"/>
  <source path="model"/>
  <source path="page"/>
  <source path="service"/>
  <source path="to"/>
  <source path="widget"/>
</module>

2. com.vivaldi.varco.manager.Manager, that inherits com.vivaldi.varco.common.Common and is a maven module with the same parent of com.vivaldi.varco.common.Common)

<module rename-to="manager">
  <inherits name="org.jboss.errai.enterprise.All" />
  <inherits name="com.google.gwt.user.User"/>


  <inherits name="org.jboss.errai.validation.Validation" />
  <inherits name="org.hibernate.validator.HibernateValidator" />
  <inherits name="org.jboss.errai.jpa.JPA"/>


  <inherits name="com.vivaldi.varco.common.Common"/>
  <inherits name="com.vivaldi.varco.shared.Shared"/>
</module>

The Common module gwt-compiles correctly on its own.  The Manager module compiles correctly only if we comment the @ApplicationScoped annotation, otherwise it produces the following error:

When we comment the @ApplicationScoped annotation, the Manager module compiles without errors and everything works. We can create instances of Keycloak and even inject it as a @Dependent bean into beans of the manager module.

I looked into the jar of the common module that we added as a dependency to the pom of the Manager module and it looks fine with classes, sources and the Common.gwt.xml in the right place.

I am wondering if there is some code generated by errai during compilation that is not picked up by the Manager module, due to some misconfiguration of the gwt-maven plugin.

            <plugin>

                </configuration>
            </plugin>

Can you give me a hint on where to look?

thanks in advance for your help
