在搭建好的 Jenkins Server 的控制面板上增加 Salve Agent 节点的时候产生了上面的谬误

通过查看 Jenkins 官网提供的信息如下

Beginning with Jenkins 2.357 (released on June 28, 2022) and the forthcoming2.361.1 LTS release, Jenkins requires Java 11 or newer. Additionally, beginningwith Jenkins 2.355 (released on June 14, 2022) and Jenkins 2.346.1 LTS (releasedon June 22, 2022), Jenkins supports Java 17. Plugins have already been preparedin JENKINS-68446. Use the Plugin Manager to upgrade all plugins before and afterupgrading to Jenkins 2.357.

能够晓得 Slave Agent 上的 JDK1.8 环境版本与 Jenkins Master Server 端的版本不匹配,我部署的 Jenkins Server2.361.2,因而须要 Slave Agent 上提供的应该是 JDK11 或者更新的版本。
