java - com.jcraft.jsch.JSchException : verify: false 错误

Question

我正在尝试 https://github.com/spring-projects/spring-integration-samples/tree/master/basic/sftp 给出的代码，当我在 Eclipse 中运行测试时，它通过了，但是当我通过 maven(mvn clean compile test)尝试它时，它失败了，堆栈跟踪如下

无法理解哪里出了问题

在pom中刚刚添加了下面的插件

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.16</version>
    <configuration>
        <reuseForks>false</reuseForks>
        <forkCount>1</forkCount>
    </configuration>
</plugin>

添加日志文件行
在 Eclipse 中

2015-07-17 19:15:33 jsch [INFO] expecting SSH_MSG_KEXDH_REPLY
2015-07-17 19:15:33 jsch [INFO] ssh_dss_verify: signature true

在 Maven 中

2015-07-17 19:13:26 jsch [INFO] expecting SSH_MSG_KEXDH_REPLY
2015-07-17 19:13:26 ServerSession [INFO] Kex: server->client aes128-ctr hmac-md5 none
2015-07-17 19:13:26 ServerSession [INFO] Kex: client->server aes128-ctr hmac-md5 none
2015-07-17 19:13:26 jsch [INFO] ssh_dss_verify: signature false

Answer 1

不幸的是，来自 jsch 的 verify: false 只是一个包罗万象的“出了点问题”。我建议您查看服务器日志。

此外，打开 debug logging for jsch并比较 eclipse 和 maven 之间的输出。

可能使用了不同的 key 文件？
