环境:
案例1:
客户端:springboot(1.5.12.RELEASE)+ spring-boot-admin-starter-client 1.5.7

admin:springboot(2.1.1.RELEASE)+ spring-boot-admin-starter-server 2.1.1

当我运行客户端,并刷新管理员应用程序.错误是"调用[asyncError()]对于具有异步状态[MUST_DISPATCH]"的请求无效;

case2:
(2.1.1.RELEASE)客户端和服务器都使用相同的版本并且具有相同的错误.

详细错误如下:

我在 Jenkinsfile（脚本化管道）中的第一阶段是 checkout scm，它简要描述了 GitHub checkouts 以及我不想在 Jenkins 控制台输出中显示的所有与修订相关的内容。

是否可以在 Jenkins 的控制台输出中隐藏它。以下控制台输出来自 Jenkins，用于结帐 scm 步骤，我想隐藏它

我试图建立一个工作，它返回以下错误：

知道如何解决吗？

根据本文https://jenkins.io/blog/2016/06/10/save-costs-with-ec2-spot-fleet/，计划将EC2 Spot实例/ fleet用作我们的jenkins从属解决方案。

如果竞价型实例节点在指定的空闲时间（我已配置5分钟）内保持空闲状态，则Jenkins释放该节点，并且我的竞价型车队节点将自动缩小。
