升级后无法连接到 Jenkins Agent

Question

将 Jenkins 从 2.257 升级到 2.339。升级后 none 个节点能够连接到主节点。 Jenkins 托管在亚马逊 Linux 上。这是我尝试将节点连接到控制器时遇到的错误：

来自 Windows 代理的日志：

我有 3 个不同的节点（Windows、Ubuntu 和 mac）。我在这三个方面都遇到了同样的错误：

Caused by: java.lang.IllegalArgumentException: invalid len argument

感谢解决此问题的任何信息。谢谢

关于您的问题有一个未解决的问题：https://issues.jenkins.io/browse/JENKINS-67258。

根据本问题的一位参与者的说法，解决方案是：

[...] upgrading SSH Build Agents / SSH Slaves Plugin to version 1.32.0 and beyond [...]

升级后无法连接到 Jenkins Agent

Unable to connect to Jenkins Agent after upgrade
