grpc bundle

Please answer these questions before submitting your issue.

What version of gRPC are you using?

I use mvn to build my project and protobuf-mavne-plugin to generate code as the grpc-java/READMME.md guide. The config is shown below.

        <grpc-netty.version>1.3.0</grpc-netty.version>
        <grpc-protobuf.version>1.3.0</grpc-protobuf.version>
        <grpc-stub.version>1.3.0</grpc-stub.version>

            <!-- thirdparty -->
            <dependency>
                <groupId>io.grpc</groupId>
                <artifactId>grpc-netty</artifactId>
                <version>${grpc-netty.version}</version>
            </dependency>
            <dependency>
                <groupId>io.grpc</groupId>
                <artifactId>grpc-protobuf</artifactId>
                <version>${grpc-protobuf.version}</version>
            </dependency>
            <dependency>
                <groupId>io.grpc</groupId>
                <artifactId>grpc-stub</artifactId>
                <version>${grpc-stub.version}</version>
            </dependency>

What JVM are you using (java -version)?

openjdk version "1.8.0_131"
OpenJDK Runtime Environment (build 1.8.0_131-8u131-b11-0ubuntu1.16.04.2-b11)
OpenJDK 64-Bit Server VM (build 25.131-b11, mixed mode)

What did you do? (Sorry for my poor English.)

I want to creat a new project in Opendaylight which will use gRPC/protobuf. The environment is apache/karaf, but these dependencies(grpc-netty, grpc-protobuf, grpc-stub) are only ordinary jar packages, I write these dependencies in my bundle pom file, when running it will give a note "jar is not a bundle". So I try to wrap these jar packages in a bundle,.

        <dependency>
            <groupId>io.grpc</groupId>
            <artifactId>grpc-netty</artifactId>
        </dependency>
        <dependency>
            <groupId>io.grpc</groupId>
            <artifactId>grpc-protobuf</artifactId>
        </dependency>
        <dependency>
            <groupId>io.grpc</groupId>
            <artifactId>grpc-stub</artifactId>
        </dependency>

I use maven-bundle-plugin according to the guide.

            <plugin>
                <groupId>org.apache.felix</groupId>
                <artifactId>maven-bundle-plugin</artifactId>
                <extensions>true</extensions>
                <configuration>
                    <instructions>
                        <Bundle-Name>${project.artifactId}</Bundle-Name>
                        <Import-Package>*</Import-Package>
                        <Export-Package>io.grpc,com.google.protobuf</Export-Package>
                        <Private-Package />
                        <Embed-Dependency>*;scope=compile|runtime;inline=false</Embed-Dependency>
                    </instructions>
                </configuration>
            </plugin>

Unfortunately, when running, it always give an error as below. After I add dependency which is about this package, it will give the same error but with another package name. For example errorprone,instrumentation,bootstrap, protobuf-java-util, netty and etc. There are so many dependencies, perhaps infinity, I think when I add a new dependency named A in pom file, A's denpendecy will also need to be added.
could not be resolved. Reason: Missing Constraint: Import-Package: io.netty.buffer; version="[4.1.0,5.0.0)"

What did you expect to see?

How to slove this problem?Who can help me? How use grpc/protobuf in apache karaf?

What did you see instead?

It seems this is a duplicate of #1565, since "bundle" seems likely to be an OSGi bundle. If something different about this bundle than OSGi bundles, please mention it.
