Jenkins java.lang.NoClassDefFoundError:com/trilead/ssh2/crypto/Base64

今天，我在ec2实例中将Jenkins版本从2.151更新到2.152，得到的第一个错误是java.lang.NoClassDefFoundError:com/trilead/ssh2/crypto/Base64

我得到这个错误：

有人知道如何解决这个问题吗？

我遇到了一个类似的问题-在升级到最新的Jenkins SSH Slaves插件（从1.29升级到1.29.1）之后，它似乎至少到目前为止消失了。

正如Eric Y.Theriault指出的，问题在于旧的SSH Slaves插件

在/plugins文件夹中：

删除ssh从属文件夹 删除以ssh从属文件开头的文件 重新启动詹金斯 如果需要，安装最新的SSH从属插件。

我该怎么做？去管理Jenkins，然后选择管理插件。然后单击检查更新，如果有，您将看到它，需要安装，然后重新启动Jenkins。您还可以在“已安装”选项卡上查看已安装的内容。希望能有帮助。我不能这样做，因为你可以从截图上看到UI被阻塞了。
