我对所有这些 OSGi 和 Maven 东西都很陌生，我正在OSGi and Apache Felix 3.0 - Beginner's Guide学习 Walid Gedeon 书中的“书架”教程。

我已经按照书中的示例进行了操作，但到目前为止在部署我的代码时遇到了一个小问题。

我收到以下错误消息：

有什么想法吗？

编辑：
据我所知，问题出在<packaging>bundle</packaging>.

您应该尝试生成清单

<plugin>
  <groupId>org.apache.felix</groupId>
  <artifactId>maven-bundle-plugin</artifactId>
  <configuration>
    <supportedProjectTypes>
      <supportedProjectType>bundle</supportedProjectType>
      <supportedProjectType>war</supportedProjectType>
    </supportedProjectTypes>
  </configuration>
  <executions>
    <execution>
      <id>bundle-manifest</id>
      <phase>process-classes</phase>
      <goals>
        <goal>manifest</goal>
      </goals>
      <configuration>
        <!-- config and instructions here -->
      </configuration>
    </execution>
  </executions>
</plugin>

<plugin>
  <artifactId>maven-war-plugin</artifactId>
  <configuration>
    <archive>
      <manifestFile>${project.build.outputDirectory}/META-INF/MANIFEST.MF</manifestFile>
    </archive>
  </configuration>
</plugin>

抛出异常是因为Bundle-SymbolicName无效：在 pom.xml 中查找属性区分大小写（查看pom.xml 参考）。把它改成这样：

<Bundle-SymbolicName>${artifactId}</Bundle-SymbolicName>
