如何通过maven-wagon-ssh/scp在ec2实例上安装文件？

Question

   The authenticity of host 'ec2-....compute-1.amazonaws.com' can't be established. 
   RSA key fingerprint is 79:..:c7.
   Are you sure you want to continue connecting? (yes/no): yes

我能做些什么，让它发挥作用，有什么建议吗？

提前感谢！

我在pom.xml中拼写错误。在重写相应的块后，它工作了：）

之前：

<plugins>
    <plugin>
     ...
     <configuration>
        <id>ec2-node</id> <-- Wrong
     ...

之后：

<plugins>
    <plugin>
     ...
     <configuration>
        <serverId>ec2-node</serverId> <-- Right
     ...
