Question

我正在学习Spring Boot和Spring Cloud。我为Eureka服务器设计了一个非常简单的应用程序。我的POM如下-

http://maven.apache.org/xsd/maven-4.0.0.xsd“> 4.0.0

<groupId>com</groupId>
<artifactId>service-discovery-ha</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>

<name>service-discovery-high-availability</name>
<description>Demo project for Spring Cloud Serivice Discovery</description>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.0.RELEASE</version>
    <relativePath /> <!-- lookup parent from repository -->
</parent>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
</properties>

            <artifactId>spring-cloud-dependencies</artifactId>

            <type>POM</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

        <artifactId>spring-boot-starter-test</artifactId>

</dependencies>

            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

但是我遇到了以下错误-

17：12：48.491 [main]错误org.springframework.boot.SpringApplication-应用程序运行失败 java.lang.NoSuchMethodError：org.springframework.boot.builder.SpringApplicationBuilder。（[Ljava / lang / Object;）V 在org.springframework.cloud.bootstrap.BootstrapApplicationListener.bootstrapServiceContext（BootstrapApplicationListener.java:161）在org.springframework.cloud.bootstrap.BootstrapApplicationListener.onApplicationEvent（BootstrapApplicationListener.java:102）在org.springframework.cloud.bootstrap.BootstrapApplicationListener.onApplicationEvent（BootstrapApplicationListener.java:68）在org.springframework.context.event.SimpleApplicationEventMulticaster.doInvokeListener（SimpleApplicationEventMulticaster.java:172）在org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener（SimpleApplicationEventMulticaster.java:165）在org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent（SimpleApplicationEventMulticaster.java:139）在org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent（SimpleApplicationEventMulticaster.java:127）在org.springframework.boot.context.event.EventPublishingRunListener.environmentPrepared（EventPublishingRunListener.java:75）在org.springframework.boot.SpringApplicationRunListeners.environmentPrepared（SpringApplicationRunListeners.java:54）在org.springframework.boot.SpringApplication.prepareEnvironment（SpringApplication.java:347）在org.springframework.boot.SpringApplication.run（SpringApplication.java:306）在org.springframework.boot.SpringApplication.run（SpringApplication.java:1260）在org.springframework.boot.SpringApplication.run（SpringApplication.java:1248）

我收到Maven安装和Spring Boot运行时错误。我的猜测是依赖错误。除此以外还有什么其他的吗？我不知道。这个错误是什么意思？请帮助我解决问题。
