好的,奇怪的问题.我有与Vagrant一​​起工作的SSH转发.但是当我使用Ansible作为Vagrant配置器时,我正试图让它工作.

我确切地发现了Ansible正在执行的操作,并且自己从命令行尝试了它,当然,它也在那里失败了.

[/common/picsolve-ansible/u12.04%]ssh -o HostName=127.0.0.1 \
 -o User=vagrant -o  Port=2222 -o UserKnownHostsFile=/dev/null \
 -o StrictHostKeyChecking=no -o PasswordAuthentication=no \
 -o IdentityFile=/Users/bryanhunt/.vagrant.d/insecure_private_key \
 -o IdentitiesOnly=yes -o LogLevel=FATAL \
 -o ForwardAgent=yes "/bin/sh  \
 -c 'git clone git@bitbucket.org:bryan_picsolve/poc_docker.git /home/vagrant/poc_docker' "
Permission denied (publickey,password).

但是,当我只运行vagrant ssh时,代理转发工作正常,我可以检查R/W我的github项目.

[/common/picsolve-ansible/u12.04%]vagrant ssh
vagrant@vagrant-ubuntu-precise-64:~$ /bin/sh  -c 'git clone git@bitbucket.org:bryan_picsolve/poc_docker.git /home/vagrant/poc_docker'

我想计算Scala类的包名称.

下面的代码有效,但似乎有点冗长

def packagename(cls:ru.ClassSymbol):String = {
    def innerPackageName(cls:JavaUniverse#Symbol):List[JavaUniverse#Name] = {
      if(cls.owner != null && cls.owner.isPackage  ) {
         List(cls.name) ::: innerPackageName(cls.owner)
      }
      else {
          List(cls.name)
      }
    }
    val owner: JavaUniverse#Symbol = cls.owner
    innerPackageName(owner).filterNot{_.toString == "<root>"}.reverse.mkString(":")
  }

有一个更好的方法吗？
