java - maven-bundle-plugin 中具有相同名称的多个引用

Question

我正在使用 maven-bundle-plugin 3.3.0 和 OSGI R6。

我有以下类(class):

//Class A
@Component (immediate = true, service = {})
public class A{
    private static B myB;
    @Reference (unbind = "unbindB")
    public static void bindB(B pB)
    {
        myB = pB;
    }

    public static void unbindB()
    {
        myB= null;
    }
}



//B class. It does not implement any interface. Hence, the service must be itself
@Component (immediate = true, service = B.class)
public class B{
@Activate
    public void activate(){
        //B activated
    }
}

运行 mvn clean install 后，maven-bundle-plugin 3.3.0 给出错误:

Bundle com.X:bundle:0.0.1-SNAPSHOT : In component com.X.A, multiple references with the same name: myB. Previous def: com.X.B, this def:
[ERROR] Error(s) found in bundle configuration

你们中有人知道这可能是什么问题吗？

绑定(bind)/取消绑定(bind)方法不能是静态的。您的代码将它们显示为静态。 DS 组件始终基于实例。
