我有 Hudson 2.1.2（不是 Jenkins），并且我已经将我的项目设置为每小时轮询我的 Mercurial 存储库以检查更改。我为我的 hudson 用户生成了一个公钥，并将它添加到我的 Mercurial 服务器上的授权密钥中。在进行每小时投票时，有时某些项目无法投票 Mercurial。这是我在 Mercurial 轮询日志中看到的示例：

[workspace] $ /usr/bin/hg incoming --style /opt/home/hudson/jobs/MyProject/workspace/tmp7506244240405638202style --no-merges --rev default --newest-first
remote: ssh_exchange_identification: Connection closed by remote host
abort: no suitable response from remote hg!
Done. Took 5.3 sec
No changes
但是，如果我单击“立即构建”，它会成功轮询、获取更改并构建。

任何想法为什么我在自动投票中出错？
