此节点的Jenkins配置如下：

请注意我已经设置了JavaPath属性,因为Jenkins“无法弄清楚java的Java版本”(这是我得到的错误消息)

知道如何解决这个问题吗？谢谢

解决方法

我有同样的问题.阅读以下文章 talking about new version后,在我正在使用的SSH插件上发现了一些错误.

所以我访问了管理插件 – >已安装 – >搜索’SSH'(通过删除选择禁用SSH相关客户端)
基本上你需要：

>已禁用 – SSH Slaves插件(可能是Jenkins附带)
>添加了SSH插件(版本2.4).

这解决了这个问题,我已经在步骤6,JENKINS-SETTING UP MASTER SLAVE ENVIRONMENT的本文档中显示的其他设置之后成功连接了.(slave.jar -jnlpUrl ….)希望这将有助于将来的某些人.
