Question

我尝试使用Kafka消息代理运行Spring Cloud Data Flow应用程序，但是mvn spring-boot:run总是失败。 Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.1.2.RELEASE:run (default-cli) on project spring-data-flow-server: An exception occurred while running. null: InvocationTargetException: org.springframework.boot.builder.SpringApplicationBuilder.<init>([Ljava/lang/Object;)V -> [Help 1]

有人知道这个问题吗？

这是我的日志：

这是MainClass：

package org.baeldung.spring.cloud.springdataflowserver;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.dataflow.server.EnableDataFlowServer;

@EnableDataFlowServer
@SpringBootApplication
public class SpringDataFlowServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(
                SpringDataFlowServerApplication.class, args);
    }

}

这是Baeldung短裙（https://www.baeldung.com/spring-cloud-data-flow-stream-processing）我已经尝试了在互联网上找到的所有内容，但是没有任何效果。即使我尝试使用mvn -X spring-boot:run使用Baeldung代码，也遇到同样的问题。

PS 01/02/2018：我已经更新了pom.xml并解决了该问题。这是我的新pom.xml（更改了Spring Boot的版本）

Answer 1

数据流服务器和Spring Boot的版本不兼容。

在这里查看版本： https://github.com/spring-cloud/spring-cloud-dataflow/releases

该服务器的最新版本是1.7.3.RELEASE，并且此版本基于Spring Boot 1.5.16。

已关闭-无法执行目标org.springframework.boot：spring-boot-maven-plugin：2.1.2.RELEASE：run
