Question

请为我在工作中遇到的问题提供专家选择..

Ant SCP任务不起作用 - 我可以使用cygwin 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（usign ant run plugin），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
我已将密码验证设置为yes，并在远程主机上重新启动sshd。

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

<plugin>

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

        <artifactId>ant-jsch</artifactId>
        <version>1.8.2</version>
    </dependency>
</dependencies>

堆栈跟踪如下：

同样在sshd日志中，我看到客户端正在使用JSCH-0.1.38，其中客户端使用的是jsch-0.1.44，我没有在ant lib或mvn中使用JSCH-0.1.38回购任何地方..

我热衷于获取密码身份验证而不是密钥身份验证，因为这是一个自动化项目，其中VM映像为每次运行创建。

Answer 1

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

注意：此任务取决于Ant中未包含的外部库分配。有关详细信息，请参阅Library Dependencies。

在那里，你会发现

jsch.jar 0.1.50或更高版本

SCP任务需要

。

JSCh is available here：

Answer 2

尝试使用Maven 3，Maven 2嵌入jsch 0.1.38，它优先于插件依赖项中指定的版本。这在Maven 3中得到了解决。
