Eureka服务器构建失败，因为com.netflix.eventbus.spi.EventBus

Question

我正在尝试使用SpringBootInitialize创建一个SpringCloudEureka服务器。

但是我得到了下面的例外。

java.lang.IllegalStateExcture：未能加载应用程序上下文造成的：org.springframework.beans.factory.不满意依赖异常：错误创建名为'org.springframework.cloud.netflix.eureka.EurekaClientAutoConfiguration$ReFreshableEurekaClientConfiguration'的bean：不满意的依赖关系表示通过字段'optionalArgs'；嵌套异常是org.springframework.beans.factory.BeanCreation异常：错误创建在类路径资源[org/spring框架/云端/网飞/eureka/配置 /DiscoveryClientOptionalArgsConfiguration.class]中定义了名为“发现”的bean：合并bean定义的后处理失败；嵌套异常java.lang.非法状态异常：无法内省类com.netflix.discovery.[AbstractDiscoveryClientOptionalArgs]来自ClassLoader[sun.misc.启动器$AppClassLoader@6bc7c054]引起原因：org.springframework.beans.factory.BeanCreationExcture：错误创建bean与名称'DiscoveryClientOptionalArgs'定义在类路径资源[org/spring框架/云/netNetflix/eureka/配置 /DiscoveryClientOptionalArgsConfiguration.class]：后处理的合并bean定义失败；嵌套异常java.lang.IllegalStateExcture：未能自省类[com.netflix.discovery.AbstractDiscoveryClientOptionalArgs]从ClassLoader[sun.misc.启动器$AppClassLoader@6bc7c054]导致：java.lang.IllegalStateExcture：未能自省类[com.netflix.discovery.AbstractDiscoveryClientOptionalArgs]从ClassLoader[sun.misc.启动器$AppClassLoader@6bc7c054]引起：java.lang.NoClassDefFoundError： com/Netflix/eventbus/spi/EventBus引起：java. lang.ClassNotFoundExcema： com. netflex. eventbus. spi.活动巴士

这是我的配置文件：

ymlfiles

server:
  port: 8761
eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false

这是我的pom.xml：

Answer 1

我已经删除了. m2文件夹几次。此问题随时发生。

以下是我的修复...

我已经改变了Spring云版本...

错误消失了！

Answer 2

我也遇到了这个错误（SpringBoot2.0.3.RELEASE）。通过删除本地maven存储库和mvn clean、mvn package、在idea中重新导入解决了这个问题。可怕的问题。
