java - Spring Boot，maven编译错误

Question

当我尝试在我的 Spring Boot 应用程序中创建 jar 包时出现此错误。我在命令行 mvn clean install 中插入，但出现此错误。项目是使用 Intelijj IDEA Ultimate 中的 Spring Initializr 创建的。

我使用 -X -X 开关重新启动了 Maven，以启用完整的调试日志记录。

Answer 1

当任何 Maven 构建失败时，请按照以下步骤操作:1)转到命令提示符并编写以下命令:mvn clean install -DskipTests2)返回Spring Boot，按Alt+F5(或更新项目)。3) 单击项目并作为 Maven 安装运行(如果包含 Maven 依赖项，还要检查部署描述符)。

希望有帮助。
