我遵循本教程https://wiki.onosproject.org/display/ONOS/Template+Application+Tutorial创建CLI命令，该命令允许我通过意图阻止OF交换机的接口。我按照这里的建议使用Bazel构建ONOS https://wiki.onosproject.org/display/ONOS/Developer+Quick+Start，一切都很顺利，甚至模板应用程序的创建和安装也很顺利。现在，在java类AppCommand中，我导入了软件包org.onosproject.openflow.controller.OpenFlowController，并在pom.xml文件中添加了artifactID和groupID的依赖关系，当我重新安装应用程序时，抛出了这个错误:

这个依赖的版本似乎有问题，但是我不明白为什么。
谢谢你的关注。
您从Karaf获得的错误消息表明您有一个不满足的依赖项。这通常发生在你有一个依赖，没有(或有不正确的)OSGi元数据在MANIFEST.MF文件。您应该打开它，并确定您使用的构建系统是否包含了它，如果包含了，则是否存在依赖项也是osgi化的包。
在这种情况下，检查包含org.onosproject.openflow.controller的Jar是否是OSGi包—它看起来不像。
