Spring Spring CLI cannot find main class after installing

Hi. I'm new to learn spring. And I learn it with the document on spring.io, which is the url. I read part 3.2.1. Manual Installation and met a problem. I have JDK 1.8, and apache-maven 3.8.1 on Windows 10 Home, 20H2. I download the spring framework spring-2.5.0 and spring-2.5.1-SNAPSHOT. I try both of them. I met some problems with the environment system variables set. I follow the guide but with problems C:\Users\ASUS>spring Error: Could not find or load main class org.spring framework.boot.loader.JarLauncher. I try to search for information about this problem but little satisfying result. My problem is similar to the question on StackOverflow Spring CLI cannot find main class after installing I edit Path with %SPRING_HOME%\bin on System Variables. I also set the Variable SPRING_HOME and the Value the path of bin D:\Downloads\spring-2.5.0\bin. Thank you!
