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 forthcoming
2.361.1 LTS release, Jenkins requires Java 11 or newer. Additionally, beginning
with Jenkins 2.355 (released on June 14, 2022) and Jenkins 2.346.1 LTS (released
on June 22, 2022), Jenkins supports Java 17. Plugins have already been prepared
in JENKINS-68446. Use the Plugin Manager to upgrade all plugins before and after
upgrading to Jenkins 2.357.

可以知道 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 Server 是 2.361.2，因此需要 Slave Agent 上提供的应该是 JDK11 或者更新的版本。
