Ant SCP 任务不起作用 - 因为我可以使用 cygwin scp

Question

请为我在工作中面临的问题提供您的专家选项。

Ant SCP 任务不起作用 - 因为我可以使用 cygwin 进行 scp。

本地环境:windows 7 64 位、Jdk 1.6.0.24、Ant-1.8.2(获取 ant 可选依赖项)、maven 2(使用 ant 运行插件)、jsch-0.1.44
远程环境:VM Labmanager 4.0、Windows Server 2008 - R2、SSH-2.0-OpenSSH_5.8、JDK 1.6.0.24

我已将密码身份验证设置为 yes 并在远程主机上重新启动了 sshd。

Maven 目标如下。 (顺便说一句，我也执行了相同的 ANT 目标，所以 Ant 和 Maven 给出了与 jsch-0.1.44 和 jsch-0.1.42 相同的结果)

<plugin>

            </target>
        </configuration>
    </execution>

同样在 sshd 日志上，我看到它说客户端正在使用 JSCH-0.1.38，其中客户端使用的是 jsch-0.1.44，我在 ant lib's 或 mvn repo 的任何地方都没有 JSCH-0.1.38。

我渴望获得密码身份验证而不是 key 身份验证，因为这是一个自动化项目，VM 镜像为每次运行创建。

您是否安装了 ant 安装可以看到的 JSch 库？ Ant scp task documentation明确指出这是必要的:

Note: This task depends on external libraries not included in the Antdistribution. See Library Dependencies for more information.

在那里，你会发现

jsch.jar 0.1.50 or later

是 SCP 任务所必需的。
