Hi,

I am not able to find solution for above error. please find my code snippet below

import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Reference;
import org.osgi.service.component.annotations.ReferenceCardinality;
import org.osgi.service.component.annotations.ReferencePolicy;

@component(/* service = ConfigUtil.class, */ immediate = true,

reference = {
@reference(name = "configutil",  bind = "bindAssetDetailsSelector" 
unbind = "unbindAssetDetailsSelector", service = DataPowerUrlUtil.class,
policy = ReferencePolicy.DYNAMIC, cardinality = ReferenceCardinality.MULTIPLE
) }
)

using maven-bundle-plugin version 4.2.1,  <artifactId>org.osgi.service.component.annotations</artifactId> verion 1.4.0,

R7 annotation

Thanks,

Sai

Hi Sai, Just check the below and try.

@Component(service =  ConfigUtil.class, configurationPolicy = ConfigurationPolicy.REQUIRE, immediate = true)
@Designate(ocd = ConfigUtilImpl.Config.class)

Thanks.

Hi @sai1007 ,

Which Maven Archetype you are using in your project? I am able to include @Reference annotation inside @Component annotation without any issue. I am using 6+ version of OSGI dependencies. Try using below if it resolves your issue-
(Also, I see there is one comma missing after 'bind = "bindAssetDetailsSelector" ' and small 'r' for Reference annotation but I believe those are just typos.)

 
<!-- OSGi Dependencies -->
<dependency>
<groupId>org.osgi</groupId>
<artifactId>osgi.core</artifactId>
<version>6.0.0</version>
<scope>provided</scope>

I think you have to use @OsgiService annotation instead of @reference
