Spring Boot CLI can be downloaded from the official site of Spring Framework:

• https://repo.spring.io/snapshot/org/springframework/boot/spring-boot-cli/2.0.0.BUILD-SNAPSHOT/spring-boot-cli-2.0.0.BUILD-SNAPSHOT-bin.zip
  
• https://repo.spring.io/snapshot/org/springframework/boot/spring-boot-cli/2.0.0.BUILD-SNAPSHOT/spring-boot-cli-2.0.0.BUILD-SNAPSHOT-bin.tar.gz
  

These sites offer manual installation through CLI distributions from the Spring software repository.

Spring Boot CLI requires Java JDK v1.8 or above in order to run. No specific environment variables are required to run the CLI; however, you may want to set SPRING_HOME to point to a specific installation. You should also add SPRING_HOME/bin to your PATH environment variable.

To test if you have successfully installed the CLI, you can run the following command:

spring --version
