Question

I add some compile dependency such as in features.xml

<bundle>mvn:org.osgi/org.osgi.resource/1.0.0</bundle>
<bundle>mvn:org.osgi/org.osgi.service.component/1.4.0</bundle>
<bundle>mvn:org.osgi/org.osgi.service.component.annotations/1.4.0</bundle>
<bundle>mvn:org.osgi/org.osgi.service.metatype.annotations/1.4.0</bundle>

but it has nothing to fix the problem this is what i get, i can't fix it the console can't get the bundle or service or component etc. anyone can give some advice for me, thank you in advance!

Answer 1

the cause is that io.github.classgraph loads class io.atomix.utils.NamedType io.atomix.cluster.protocol.HeartbeatMembershipProtocol$Type while org.apache.felix.framework loads class io.atomix.utils.NamedType, but HeartbeatMembershipProtocol$Type should be typecast to NamedType。

The solved method is to add some DynamicImport-Package attribute in pom.xml

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.felix</groupId>
            <artifactId>maven-bundle-plugin</artifactId>
            <version>4.1.0</version>
            <extensions>true</extensions>
            <configuration>
                <instructions>
                    <DynamicImport-Package>io.atomix.cluster.*,io.atomix.primitive.*,io.atomix.core.*,io.atomix.protocols.*</DynamicImport-Package>
                </instructions>
            </configuration>
        </plugin>
    </plugins>
</build> 

so when your bundle is loaded, the dependency jars will be loaded.

thanks those who give me clues!
