[英]Execution default-cli of goal org.springframework.boot:spring-boot-maven-plugin:2.4.4:repackage failed: Unable to find main class
我是 Springboot 的新手，正在尝试重新创建我的教师应用程序，但运行时出现错误
mvn clean package spring-boot：重新包装
这表示它在后端模块中找不到主要的 class。 错误信息：
[INFO] 测验的根源.......................................成功 [ 0.386 s]
[信息] 后端................................. 失败 [ 11.162 秒]
[INFO] 前端.......................... 跳过 [INFO ] ------------------------------------------------- ----------------------
[信息] 构建失败 [信息] ------------------------------------------ ----------------------
[错误] 无法在项目后端执行目标 org.springframework.boot:spring-boot-maven-plugin:2.4.4:repackage (default-cli)：执行目标 org.springframework.boot:spring-boot 的 default-cli -maven-plugin:2.4.4:repackage failed: Unable to find main class -> [帮助 1]
运行应用程序的@Springbootapplication main class 位于前端模块中。 我如何告诉应用程序？ 我通过在根 pom 文件中添加 springgboot-maven-plugin 来尝试这些步骤，但仍然没有运气。 我还尝试减少包的数量并使 application.class 尽可能靠近 src 文件夹，尽管这些都不重要，因为它适用于我的老师。
这是我的根 pom 文件：

我在这里遇到了类似的错误，我的代码没有找到主要的 class，我将此属性添加到 pom.xml 文件中：
<spring-boot.repackage.skip>true</spring-boot.repackage.skip>
一切都在这里工作。
我找到了使用命令的正确方法
mvn clean package spring-boot：重新包装
是导航到仅包含主要 class 的模块（在我的情况下为前端模块），然后运行
mvn 干净安装
