由于com.netflix.eventbus.spi.EventBus导致尤里卡服务器构建失败

Question

我正在尝试创建一个具有spring启动初始化的服务器。

但我得到了下面的例外。

org.springframework.beans.factory.UnsatisfiedDependencyException:错误创建名为'org.springframework.cloud.netflix.eureka.EurekaClientAutoConfiguration$RefreshableEurekaClientConfiguration'：的bean，通过字段‘optionalArgs’表示不满意的依赖关系；嵌套异常是创建类路径资源org/springframework/cloud/netflix/eureka/config /DiscoveryClientOptionalArgsConfiguration.class:中定义的名为'discoveryClientOptionalArgs‘的bean的org.springframework.beans.factory.BeanCreationException:错误-合并bean定义的后处理失败；嵌套异常是com.netflix.discovery.AbstractDiscoveryClientOptionalArgs :无法从ClassLoader sun.misc.Launcher$AppClassLoader@6bc7c054中自省类/DiscoveryClientOptionalArgsConfiguration.class：，原因是: org.springframework.beans.factory.BeanCreationException:错误创建了类路径资源org/springframework/cloud/netflix/eureka/config /DiscoveryClientOptionalArgsConfiguration.class:中定义的名称为'discoveryClientOptionalArgs‘的bean，合并后的bean定义处理失败；嵌套的例外是java.lang.IllegalStateException:未能从ClassLoader sun.misc.Launcher$AppClassLoader@6bc7c054中自省类sun.misc.Launcher$AppClassLoader@6bc7c054，原因是: java.lang.IllegalStateException:失败反思ClassLoader sun.misc.Launcher$AppClassLoader@6bc7c054的类java.lang.IllegalStateException，原因是: java.lang.NoClassDefFoundError: com/netflix/eventbus/spi/EventBus，由: java.lang.ClassNotFoundException: com.netflix.eventbus.spi.EventBus引起

这是我的配置文件：

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

这是我的pom.xml

Answer 1

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清理、mvn包，在idea中重新导入来解决这个问题。恐怖的问题。

Answer 2

我已经删除了几次.m2文件夹。这个问题随时都会发生。

以下是我的解决办法..。

我把春天的云版本从后面.Hoxton.SR11到Greenwich.SR1

错误消失了！
