我有一个以这种方式声明的类：
@ApplicationScoped
public class MessageReceiverImpl implements MessageReceiver {
@Inject
MessageHandler messageHandler;
...
}
我将它注入另一个类：
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]
当我尝试启动我的应用程序时，我收到以下异常：
mvn wildfly-swarm:run
您可能会注意到同一个类在可能的bean列表中出现两次。
这一切都正常，直到我在一个名为“core”的独立项目中隔离这些类，并开始在具有核心作为依赖项的不同maven项目中使用它们。
我的猜测是这个项目分离引起的问题。当依赖项来自不同的项目时，我是否需要做一些不同的事情？
我正在运行应用程序：
<groupId>com.company</groupId>
<artifactId>core</artifactId>
<version>0.0.1</version>
<packaging>jar</packaging>
Wildfly-swarm生成一个超级jar，包含一切，使最终的jar独立。在最终的jar里面有一个带有所有依赖项的“maven存储库”，而且只有一个来自“com.company”的jar，这是我期待的那个（核心）。
pom文件是这样的：
核心：
<dependency>
<groupId>com.company</groupId>
<artifactId>core</artifactId>
<version>0.0.1</version>
</dependency>
