Wso2 Jax-RS服务项目无法加载Wso2依赖项

Question

I am developing a Jax-RS Service project using the Wso2 Development Studio. I want to use some classes of other Wso2 modules. So i try to include those in the project as maven dependencies.

However it seems that i am doing something wrong because i can not make the dependencies to work.

For example i am having these dependencies

 <dependencies>
    <dependency>
      <groupId>javax.ws.rs</groupId>
      <artifactId>jsr311-api</artifactId>
      <version>1.1.1</version>
      <scope>provided</scope>
    </dependency>
    <dependency>
      <groupId>org.wso2.carbon</groupId>
      <artifactId>org.wso2.carbon.user.core</artifactId>
      <version>4.2.0</version>
    </dependency>
    <dependency>
      <groupId>org.wso2.carbon</groupId>
      <artifactId>org.wso2.carbon.core</artifactId>
      <version>4.2.0</version>
    </dependency>
    <dependency>
      <groupId>org.wso2.carbon</groupId>
      <artifactId>org.wso2.carbon.core.common</artifactId>
      <version>4.2.0</version>
    </dependency>
  </dependencies>

But when i try to use something out of those packages i get a class not found

import javax.naming.directory.DirContext;
import javax.ws.rs.*;
import org.wso2.carbon.user.core.UserStoreException;


@Path("/")
public class Users {

    @GET
    public String getUsers()
    {
        return "this is v0.0.1";
    }

    @POST
    @Consumes("application/json")
    public String createUser() throws UserStoreException
    {
        throw new UserStoreException("this is an erro message but it worked");
        return "creatd";
    }
}

In this example the UserStoreException can't even be imported.

This is how i import the packages needed

<plugin>
        <groupId>org.apache.felix</groupId>
        <artifactId>maven-bundle-plugin</artifactId>
        <version>3.3.0</version>
        <extensions>true</extensions>
        <configuration>
          <obrRepository>NONE</obrRepository>
          <instructions>
            <Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
            <Bundle-Name>${project.artifactId}</Bundle-Name>
            <Bundle-Version>0.0.1</Bundle-Version>
                        <Export-Package>
                            example.*
                        </Export-Package>
            <Import-Package>
                  org.wso2.carbon.*,
                  org.apache.commons.logging.*,
                  org.osgi.framework.*,
                  javax.naming.*,
                  org.osgi.service.component.*
           </Import-Package>
          </instructions>
        </configuration>
      </plugin> 

do i have something wrong in the import ?

What should i do to import Wso2 dependencies successfully?

Since wso2 artifacts are not synched with the maven central you may get errors when trying to build the project. Could you please add the following repositories to your pom.xml and do the build.

<repositories>
        <!-- WSO2 released artifact repository -->
        <repository>
            <id>wso2.releases</id>
            <name>WSO2 Releases Repository</name>
            <url>http://maven.wso2.org/nexus/content/repositories/releases/</url>
            <releases>
                <enabled>true</enabled>
                <updatePolicy>daily</updatePolicy>
                <checksumPolicy>ignore</checksumPolicy>
            </releases>
        </repository>

        <!-- WSO2 Snapshot artifact repository -->
        <repository>
            <id>wso2.snapshots</id>
