OpenFeign ClassNotFoundException

如何解决OpenFeign ClassNotFoundException

我正在尝试在我的应用程序中使用 OpenFegin，但是当我运行 SpringBoot 应用程序时，我收到以下异常。

    OpenJDK 64-Bit Server VM warning: Options -Xverify:none and -noverify were deprecated in JDK 13 and will likely be removed in a future release.

我尝试调试并找到了这个。

我没有使用 OpenFeign Micrometer，但我的项目中已经有了“Micrometer”。我也尝试使用 feign.metrics.enabled=false 禁用指标，但没有区别。

我在 AdoptOpenJDK 14 上运行，我的应用程序是 Kotlin 应用程序。

我不确定这是否与 Micrometer 或完全不同的问题有关。我该如何解决这个问题？
