Eureka is a service discovery component that provides registry functions such as service registration and discovery. An error is reported when starting Eureka application using spring boot:

20:36:17.646 [restartedMain] ERROR org.springframework.boot.SpringApplication - Application run failed
java.lang.NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder.<init>([Ljava/lang/Object;)V

My POM file is written as follows:

Solution:

Modify the POM file and modify the version of the parent, as shown below

<parent>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-parent</artifactId>
	<version>1.5.4.RELEASE</version>
	<relativePath /> <!-- lookup parent from repository -->
</parent>
