spring boot和spring cloud之间应该有不匹配的版本。如果使用Spring Boot版本2.2.0.RELEASE，则必须使用Spring Cloud版本Hoxton.RC1。如果您使用的是Spring Boot 2.1.9.RELEASE版本，则必须使用Spring Cloud版本的Greenwich.SR3。
下面是示例：

在GitHub上打开了一个问题：#1491。
通过清理maven repo来解决：rm -r $HOME/.m2
答案 2 :(得分：1)
我能够通过调整我的spring-boot和spring-cloud版本，特别是 spring-boot-starter-parent 和 spring-cloud-dependencies 来解决此问题。 >。
要查看最新的兼容版本，我使用SpringInitializr创建了一个eureka服务器项目，然后查看了生成的pom.xml。
要通过上面的链接创建一个尤里卡项目：
单击“浏览”按钮以查看生成的pom.xml。
