问题
I have one class declared this way:
@ApplicationScoped
public class MessageHandlerImpl implements MessageHandler {
...
}
and I inject it on another class like this:
@ApplicationScoped
public class MessageReceiverImpl implements MessageReceiver {
@Inject
MessageHandler messageHandler;
...
}
When I try to start my application I receive the following exception:
org.jboss.weld.exceptions.DeploymentException: WELD-001409: Ambiguous
dependencies for type MessageHandler with qualifiers @Default at
injection point [BackedAnnotatedField] @Inject
com.company.core.WSClient.messageHandler at com.company.core.WSClient.messageHandler(WSClient.java:0)
Possible dependencies:
- Managed Bean [class com.company.core.MessageReceiverImpl] with qualifiers [@Any @Default],
- Managed Bean [class com.company.core.MessageReceiverImpl] with qualifiers [@Any @Default]
You might notice that the same class appears two times on the possible beans list.
This was all working fine until I isolated those classes on a separated project called "core" and started using them on a different maven project that has the core as a dependency.
My guess would be that the problem its caused by this project separation. Do I need to do something different when the dependencies come from a different project?
I'm running the application with:
mvn wildfly-swarm:run
Wildfly-swarm generates an uber-jar with everything to make the final jar independent. Looking inside the final jar there is a "maven repository" with all the dependencies and there is only one jar from "com.company" which is the one I was expecting (the core).
The pom files are like this:
Core:
<groupId>com.company</groupId>
<artifactId>core</artifactId>
<version>0.0.1</version>
<packaging>jar</packaging>
Depedent project:
<dependency>
<groupId>com.company</groupId>
<artifactId>core</artifactId>
<version>0.0.1</version>
</dependency>
mvn dependency:tree
