【问题描述】：

我的 ant build.xml 通过 ssh 与另一台计算机连接时遇到问题。我有一台 IP 地址为：10.62.11.40 的计算机，我有一个 ant 代码可以连接这台计算机：

<available property="ant-jsch.present" file="${ant.home}/lib/ant-jsch.jar"/>
            <fail if="ant-jsch.present" message="Please remove ant-jsch.jar from ANT_HOME/lib see [http://ant.apache.org/faq.html#delegating-classloader]"/>

        <path id="jsch.path">
            <pathelement location="lib/ant-jsch.jar" />
            <pathelement location="lib/jsch-0.1.44.jar" />
        </path>

        <taskdef name="scp" classname="org.apache.tools.ant.taskdefs.optional.ssh.Scp" classpathref="jsch.path" />
        <taskdef name="sshexec" classname="org.apache.tools.ant.taskdefs.optional.ssh.SSHExec" classpathref="jsch.path" />

        <echo message="Start Working...123"/>
        <sshexec host="10.62.11.40" username="${username}" password="${password}" command='cmd /C mkdir "C:\\\\newFolder"' trust="true" failonerror="true" verbose="true"/>

它是“ant build.xml”命令的一段输出：

  [sshexec] ssh_rsa_verify: signature true
  [sshexec] Permanently added '10.62.11.40' (RSA) to the list of known hosts.
  [sshexec] SSH_MSG_NEWKEYS sent

  [sshexec] cmd : cmd /C mkdir "C:\\\\newFolder"
  [sshexec] Caught an exception, leaving main loop due to SSH_MSG_DISCONNECT: 2
fork failed: Resource temporarily unavailable
  [sshexec] Disconnecting from 10.62.11.40 port 22

BUILD FAILED
C:\isNowe\build.xml:11: The following error occurred while executing this line:
C:\isNowe\lib\macros\lib\is2k8.xml:36: Remote command failed with exit status -1

通过普通终端与这台计算机连接正常，我可以在这台计算机上连接并做一些事情。

'is2k8.xml:36'

这一行是

<sshexec host="10.62.11.40" username="${username}" password="${password}" command='cmd /C mkdir "C:\\\\newFolder"' trust="true" failonerror="true" verbose="true"/>

你有什么问题吗？

【问题讨论】：

你的服务器是什么？ cygwin-ssh?

标签： ant ssh jsch

【解决方案1】：

您已成功连接到远程主机，但远程命令失败：

cmd /C mkdir "C:\\\\newFolder"'

你能从命令行成功运行这个命令吗？

添加 -d 标志以从 Ant 获取调试输出也可能会有所帮助。
