小编Léo*_*der的帖子

我正在运行几个项目作为 Spring Boot 应用程序，其中一个项目特别无法启动并抛出：

java.lang.ClassNotFoundException: kotlinx.coroutines.debug.AgentPremain
    at java.net.URLClassLoader.findClass(URLClassLoader.java:382)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:418)

Exception in thread "main" FATAL ERROR in native method: processing of -javaagent failed
Disconnected from the target VM, address: '127.0.0.1:64279', transport: 'socket'

Process finished with exit code 1

命令行有选项：

-javaagent:[...].m2/repository/org/jetbrains/kotlinx/kotlinx-coroutines-core/1.5.0/kotlinx-coroutines-core-1.5.0.jar

这个罐子是存在的。

将我的 Intellij'Idea 更新到 2021.2 后发生这种情况

此问题仅在调试模式下发生。

知道如何解决这个问题吗？

我想WebClient在我的服务类中使用特定的。我在构建它时遇到了这个异常：

看起来这是一个依赖问题，但一个很好的旧干净安装没有改变任何东西。

我需要在我的配置中手动指定一个 Bean 吗？

我的课很简单：

@Service
class Client {
    private val webClient = WebClient.builder() …
