我有Hudson 2.1.2（不是Jenkins），我已经设置我的项目每小时轮询我的Mercurial存储库以检查更改。我为我的哈德森用户生成了一个公钥，并将其添加到我的Mercurial服务器上的授权密钥。在进行每小时轮询时，有时一些项目无法轮询Mercurial。以下是我在Mercurial Polling Log中看到的一个例子：

[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，如果我点击“立即构建”，它会成功进行轮询，获取更改和构建。
