Question

我想在Mac OS X下的Apache Ant中使用sshexec任务，如下所示：

<!-- ... -->
<target name="uname">
    <sshexec host="${host}" keyfile="${user.home}/.ssh/id_rsa" username="${user}" command="uname -ar" />
</target>
<!-- ... -->

但是我只会在“ant uname”中收到错误“Auth取消”：

在玩完之后，我发现我必须将我的密码作为参数“passphrase”添加到任务中：

<!-- ... -->
<target name="uname">
    <sshexec host="${host}" keyfile="${user.home}/.ssh/id_rsa" passphrase="my.secret.passpgrase" username="${user}" command="uname -ar" />
</target>
<!-- ... -->

但我已经完美地设置了Mac OS X，并将密码管理功能集成到我的钥匙串中。所以我不必每次都输入密码。

有没有办法让sshexec和scp任务可以使用存储在我的钥匙串中的短语？

我自己也遇到了这个问题并提供了另一种解决方案：从密钥对中删除密码。似乎jsch无法访问本地密钥链，因此您必须将密码短语放入ant任务或将其从密钥中删除。以下是删除它的方法：

prompt% ssh-keygen -p
Enter file in which the key is (~/.ssh/id_rsa): <just hit return if the file printed before the prompt is your key file>
Enter old passphrase: <your current passphrase>
Key has comment '~/.ssh/id_rsa'
Enter new passphrase (empty for no passphrase): <hit return to remove the passphrase>
Enter same passphrase again: <hit return again>
Your identification has been saved with the new passphrase.
