无法执行目标org.springframework.boot：spring-boot-maven-plugin：1.5.8.RELEASE：run

Question

你能帮助我吗？ 我不明白为什么会收到该错误。

我的日志：

我的主班：

    package com.db.databaseproject;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;

  @SpringBootApplication
public class DataBaseProjectApplication {

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

ServletInitializer类：

package com.db.databaseproject;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(DataBaseProjectApplication.class);
    }

}

我通过InteliJ的Spring初始化程序创建了此类和POM。 我尝试通过命令“ mvn spring-boot：run”运行我的应用程序。 我有所有的依赖关系，我用spring参考检查了我的代码，我不明白这一点。

编辑：我的POM现在看起来像

现在我得到：在当前项目和插件组[org.apache.maven中，找不到前缀为'spring-boot'的插件。 可从存储库[本地（C：\\ Users \\ Pawel.m2 \\ repository），中央（https：//repo.maven.apache.org/maven2）]的存储库中找到org.codehaus.mojo插件]-> [帮助1]

刷新：伙计们仍然无法正常工作，有什么可以帮助的吗？

Answer 1

您必须找出这两个类在哪些JAR中： org.springframework.util.ObjectUtils和org.springframework.validation.DataBinder 。 这两个JAR的版本不匹配。

我的直觉是

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>5.0.1.RELEASE</version>
    </dependency>

要么

    <dependency>
        <groupId>org.springframework.shell</groupId>
        <artifactId>spring-shell-starter</artifactId>
        <version>2.0.0.M2</version>
    </dependency>

引入不同版本的Spring。 使用mvn dependency:tree查看所有依赖项，并检查是否存在重复项，并确保所有Spring依赖项具有相同的版本。
