【问题描述】：
我正在尝试将我的 grails 应用程序升级到 Grails 4.0.3。对于 REST 请求，我尝试使用 micronaut-http-client 插件 -> build.gradle ：
dependencies {
compile 'io.micronaut:micronaut-http-client:2.0.0'
}
不幸的是，当我使用grails run-app 运行应用程序时，会出现此堆栈跟踪：

我进行了研究，但无法找到解决方案。
任何帮助将不胜感激。先谢谢了~

Grails 4.0.3 基于 mn 1.x - 如果您使用匹配的版本，它应该可以工作。 4.1.x 将使用 mn 2.x
