Maven Wagon SCP无法建立连接

问题描述：

我试图将资源复制到另一个位置。我使用maven wagon-ssh插件来执行此操作。它在当地很好，我在使用Hudson/Jenkins时遇到了问题。Maven Wagon SCP无法建立连接

我settings.xml文件看起来像这样：

<servers> 
    <server> 
     <id>iq</id> 
     <configuration> 
      <knownHostsProvider implementation="org.apache.maven.wagon.providers.ssh.knownhost.NullKnownHostProvider"> 
       <hostKeyChecking>no</hostKeyChecking> 
      </knownHostsProvider> 
     </configuration> 
     <username>user</username> 
     <password>pass</password> 
    </server> 
</servers>

我想this answer to skipping checking因为我得到：

Are you sure you want to continue connecting? (yes/no): The authenticity of host 'address' can't be established. 
RSA key fingerprint is 10:.......:bb.

，但现在我得到：

答

您确定要继续连接吗？（是/否）：主机'地址'的真实性无法建立。 RSA密钥指纹为10：.......：bb。

是的，这也发生在我们身上。你似乎已经解决了你的问题，但我想我会为后人添加更多细节。

在Jenkins下运行时，没有控制台，因此没有人确认任何新的ssh密钥或maven服务器的密钥更改。为了解决这个问题，我们以jenkins用户的身份登录到我们的jenkins框，并从命令行手动执行工作区目录中的作业。这会将相应的行添加到jenkins用户的ssh配置文件中。

键入“是”一堆时间似乎增加了知名主机文件的关键并解决了问题，虽然您将需要重新启动作业以确保。

此外，我还没有尝试过，但您可以将以下内容添加到~jenkins/.ssh/config。见：How to Avoid Maven builds stall on ssh host authenticity problem?

StrictHostKeyChecking no

希望这可以帮助别人。

答

的问题是， RSA密钥未交换。

所以我做的是，我连接命令行的两台服务器。因此RSA密钥被存储并且

Are you sure you want to continue connecting? (yes/no): The authenticity of host 'address' can't be established. 
RSA key fingerprint is 10:.......:bb.

此消息停止。它现在完美运行

如果它适合你，你可以接受你自己的答案。 – ArtB

谢谢@ArtB。我忘了那个 –

@Gray我正在通过jenkins执行它，所以按下输入不会有帮助:) –

maven显然需要一个ssh-rsa条目。您可以通过发行获得支持SSH-RSA进入

SSH-键扫描-t RSA YOUR_REMOTE_HOSTNAME >>的〜/ .ssh/known_hosts中
