java - 春季启动构建失败

问题描述

我正在 Spring Boot 中开发用户管理 API，我制作了最需要的实体类、服务和存储库，但我错过了一些我看不到的东西。我想出了我的 pom.xml 来执行我的主类，但它没有找到它。当我在我的项目目录中运行“./mvnw spring-boot:run”时，它引发了以下构建失败：

Error: Could not find or load main class br.com.atosit.UserManagementApiApplication
Caused by: java.lang.ClassNotFoundException: br.com.atosit.UserManagementApiApplication

这是我的 pom.xml：

拜托，我会很高兴有任何帮助！谢谢

解决方案

好的。我应该感到疲倦和困惑。我在项目 pom.xml 中进行了错误的配置。在 start-class 之前有一个包：

错误的配置：

<properties>
    <start-class>br.com.atosit.UserManagementApiApplication</start-class>
</properties>

新配置（启动正常）

 <properties>
        <start-class>br.com.atosit.missingpackage.UserManagementApiApplication</start-class>
    </properties>
