我已经更新了 kubernetes 插件和 kubernetes-credentials 插件：
'kubernetes:1.18.3',
'kubernetes-credentials:0.4.0'
到
'kubernetes:1.25.3'
'kubernetes-client-api:4.9.1-1'
'kubernetes-credentials:0.6.2'
现在我可以在 Jenkins 日志中看到以下异常。日志中充斥着此警告消息。我能够按预期运行所有作业，并且没有任何问题。我们有两个与 jenkins 一起使用的 kubernetes 集群。Jenkins 在带有kubernetes 版本 v1.16.3的裸机集群上运行。
