Wso2 Jax-RS 服务项目无法加载 Wso2 依赖项

【问题标题】：Wso2 Jax-RS Service project cant load Wso2 dependenciesWso2 Jax-RS 服务项目无法加载 Wso2 依赖项

【问题描述】：

我正在使用 Wso2 Development Studio 开发一个 Jax-RS 服务项目。 我想使用其他 Wso2 模块的一些类。所以我尝试将项目中的那些作为 maven 依赖项包含在内。

但是，我似乎做错了什么，因为我无法使依赖项工作。

例如，我有这些依赖项

 <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>

但是当我尝试使用这些包中的某些东西时，我得到了一个找不到的类

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";
    }
}

在此示例中，UserStoreException 甚至无法导入。

这就是我导入所需包的方式

<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>

我的导入有什么问题吗？

如何才能成功导入 Wso2 依赖项？

    【解决方案1】：

    由于 wso2 工件未与 maven Central 同步，因此您在尝试构建项目时可能会出错。 您能否将以下存储库添加到您的 pom.xml 并进行构建。

    <repositories>
        <!-- WSO2 released artifact repository -->
        <repository>

    【讨论】：

    • 我确实添加了这些，但我在本地运行 mvn eclipse:eclipse 并下载了许多 jar。但是，我正在将 carbon 应用程序部署到服务器，但它仍然说它没有找到 UserStoreException。构建应用程序时我必须做一些特定的事情吗？
    • 您是否在 import-package 部分正确提及了所有导入包？
    • 我更新了显示Import-package 的问题。它似乎是正确的？
    • 附上来自服务器的完整堆栈跟踪，希望它能给你一个见解。谢谢。
    • 你放这个jar文件的产品和版本是什么？
