Question

我在安装Spring CLI后尝试运行快速启动cli示例。

https://docs.spring.io/spring-boot/docs/current/reference/html/getting-started-installing-spring-boot.html#getting-started-cli-example

开：$ spring run app.groovy

错误：

任何人都请指导我。

Answer 1

我不确定你是否可以尝试一下：

--add-modules=java.sql

我认为spring.boot是一个自动模块。自动模块不会声明它依赖，因此您必须使用--add-modules来确保解析所需的任何显式模块。如果spring.boot是一个显式模块，那么我认为它需要java.sql并且你不会遇到这个问题。

Answer 2

这是因为您运行的Java版本与您所拥有的Groovy版本错误。我目前安装了Java 11和Java 8，默认为Java 11，但是我可以使用已设置的几个别名轻松地在它们之间切换。今天早些时候，我尝试使用Spring Boot CLI运行一个简单的RestController并遇到与您相同的错误。我意识到我正在运行Java 11，将其切换为8，重新运行该命令，一切正常。
