有人可以帮助我，为什么这个电话不再适用于Apache Karaf 3.0.2。我验证它在3.0.1版本中运行。所有实例都已启动并正在运行，但我无法直接从命令行连接到我的某个实例。
su - karaf -c " client -h localhost -a 8101 -u karaf -r 50 -d 2 \" instance:connect -u karaf -p karaf test1 \\\" feature:repo-list \\\" \" "
Logging in as karaf
455 [sshd-SshClient[bea319b]-nio2-thread-1] WARN org.apache.sshd.client.keyverifier.AcceptAllServerKeyVerifier - Server at [localhost/127.0.0.1:8101, DSA, b6:f6:d6:3f:8b:2f:ad:a4:0f:3f:3d:c3:7b:96:fd:ae] presented unverified {} key: {}

该调用是自动过程的一部分，我无法直接连接到特定实例。是否需要任何特定配置，这在3.0.1中是不必要的？
更新＃1：
我添加了详细选项...它是否为您提供了任何提示？

我将记录器切换到DEBUG，我发现了这个异常：
