未能执行目标 org.springframework.boot:spring-boot-maven-plugin:2.2.5.RELEASE:run (default-cli)

Question

我是 spring boot 的新手，我正在尝试运行一个使用 maven spring-boot:run 运行的应用程序。 我从 spring initializr 下载了一个 spring 应用程序，并尝试在 IntelliJ IDE 社区版 2019.3.3 中运行它，但出现以下错误：

无法在项目演示中执行目标 org.springframework.boot:spring-boot-maven-plugin:2.2.5.RELEASE:run (default-cli)：应用程序以退出代码完成：1

我的代码是：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

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

我的 pom.xml 文件是：

            </plugin>
        </plugins>
    </build>
</project>

后来我改用 NetBeans IDE 并尝试运行该应用程序，但遇到了同样的错误。 完整的错误堆栈是：

无法在项目演示中执行目标 org.springframework.boot:spring-boot-maven-plugin:2.2.5.RELEASE:run (default-cli)：应用程序以退出代码完成：1 -> [Help 1] org.apache .maven.lifecycle.LifecycleExecutionException: 无法执行目标 org.springframework.boot:spring-boot-maven-plugin:2.2.5.RELEASE:run (default-cli) on project demo: Application finished with exit code: 1

Answer 1

上面的错误基本上是由于maven for spring-boot的插件问题

如果你想运行，你也可以以不同的方式运行项目

首先通过运行为项目创建一个jar

mvn 全新安装

然后从普通的java命令运行jar

java -jar jar-localtion .jar

如果想使用任何特定的配置文件运行，请使用它

java -Dspring.profiles.active= -jar jar- localtion .jar

Answer 2

我有同样的问题，只需单击鼠标右键将鼠标悬停在 pom.xml 中的“spring-boot-maven-plugin”（红色警告颜色）上，选择“Maven”，然后选择“下载源”即可解决它

下载资源花了几秒钟，红色/警告消失了。
