[英]Failed to execute goal org.codehaus.mojo:exec-maven-plugin:3.0.0:exec (default-cli)
I just started to learn spring boot.刚开始学spring开机。 I only coded a simple hello world program but whatever i try i can't fix this problem.
我只编写了一个简单的 hello world 程序,但无论我尝试什么,我都无法解决这个问题。
There is my pom file:有我的 pom 文件:

I've tried to add main class and some plugins to the pom file but none of them seem to worked.我尝试将 main class 和一些插件添加到 pom 文件中,但它们似乎都不起作用。 And i changed the java version on pom but that didn't work either.
我在 pom 上更改了 java 版本,但这也不起作用。
The issue is java version.问题是java版本。 You are using Java 8 with Spring Boot 3.0.0 and that is incorrect because Spring Boot 3.0.0 only supports Java 17. So there are two ways to fix the problem.
