我使用spring初始化工具生成一些工作骨架, 我采用MAVEN PROJECT& amp; JAVA& SPRING BOOT 2.0.0
当我运行mvn clean install
(没有对项目进行任何更改)时,我收到以下错误,知道如何克服它吗?

更新
这是pom.xml文件,我没有改变任何内容......

答案 0 :(得分:1)
可能是您添加的依赖项
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-rest</artifactId>
</dependency>
似乎在初始化时需要数据库连接,也许在application.properties文件上提供数据库连接,或者删除此依赖关系,直到数据库构建可能对您有所帮助。
还要确定确切原因,请共享您的application.properties文件
